NATO: Congress Addresses
Expansion of the Alliance
On April 30, 1998, the Senate gave its consent to the amendment of the North
Atlantic Treaty to admit Poland, the Czech Republic, and Hungary by a vote of 80-19.
The President signed the Resolution of Ratification on May 22, 1998. On March 12,

1999, the three countries formally joined the alliance.

On July 8, 1997, NATO named Poland, the Czech Republic, and Hungary as
candidate states for admission to the alliance. On June 3, 1997, Representative
Benjamin Gilman and others proposed the European Security Act of 1997 (H.R.
1758). It was engrossed in H.R. 1757, the Foreign Relations Authorization Act, on
June 11, 1997. The Conference Report (H.Rept. 105-432) was sent to the House
floor March 10, 1998. The House passed H.R. 1757 by voice vote on March 26,
1998, and the Senate by a vote of 51-49 on April 28, 1998. The bill became the
European Security Act of 1998, and is Title XXVII of the omnibus appropriations
measure that the president signed on October 21, 1998 (P.L. 105-277; H.R. 4328).
The European Security Act endorses NATO enlargement; urges that the door
to alliance membership be kept open should a first round of enlargement occur;
specifically urges consideration of the Baltic states, Bulgaria, and Romania; outlines
recommendations for arms control negotiations that affect new and current members;
and states that the European allies should pay the bulk of the costs of enlargement.
The act states that no commitments be made to Russia over deployments of
conventional and nuclear forces in new member states that would put such states in
a category different from that of current members. In addition, NATO should make
no commitments to Russia limiting the construction of defense infrastructure or
deployment of reinforcements in a new member state’s territory.
On May 27, 1997, NATO and Russia signed the “Founding Act,” which outlines
their future security relationship.
On February 11, 1998, President Clinton sent the protocols of accession to the
Senate (Treaty Doc. 105-36). The Senate Foreign Relations Committee drafted a
Resolution of Ratification, which it adopted by a vote of 16-2 on March 3, 1998, and
sent to the full Senate, accompanied by Exec. Rpt. 105-14.
At the April 23-25 NATO summit in Washington, the allies did not invite new
members, but reaffirmed their policy of keeping the door open to qualified candidates.

NATO: Congress Addresses
Expansion of the Alliance
The 105th Congress considered legislation and amendment of the North Atlantic
Treaty that could have important implications for future U.S. security interests in
Europe. Legislation has passed Congress calling for NATO expansion and
authorizing financial assistance to candidates for membership. The Senate approved
a Resolution of Ratification to amend the North Atlantic Treaty to admit Poland, the
Czech Republic, and Hungary to the alliance. All NATO states must approve the
three countries’ admission for them to join. The debate over expansion, or
“enlargement,” is taking place at a moment when NATO’s mission is unclear.
Clarification of the alliance’s purpose most likely hinges upon the ability of the United
States and its allies to come to an agreement over their mutual security interests, and
how best to protect them. The debate over enlargement has addressed key issues
surrounding those interests.
A central factor in the debate over enlargement has been how to build stability
in central Europe, and to do so without threatening or isolating Russia. Both
proponents and opponents of NATO expansion wish to avoid a return to the era of
enmity between Russia and the West. Some Members of Congress believe that
enlargement would enhance stability by providing NATO’s security guarantee for
candidate states working to construct viable democracies and free-market systems.
Other Members believe that too rapid expansion of the alliance could fuel nationalist
sentiment in Russia, where some political groups contend that NATO is intent upon
circumscribing Moscow’s influence in a region of traditional interest. Some Members
support enlargement, but oppose giving Russia any role in NATO decisionmaking
within the cooperative framework between the alliance and Moscow, structured in
May 1997.
For the United States and its allies, the conflict in Kosovo has thrown into relief
some of the differing perceptions of interests among NATO states. Some European
allied governments believe that ethnic violence in the Balkans, by spreading
nationalistic sentiments and a continuing flow of refugees, could unsettle west
European societies. Divergences between the Clinton Administration and allied
governments over how to bring peace to Bosnia persist, as do differences over next
steps to resolve the crisis in Kosovo. Many Members of Congress remain opposed
to the deployment of U.S. ground forces in Bosnia and Kosovo.1

Steven Woehrel. Regularly updated.

Disagreements over Bosnia are relevant to the debate over enlargement because
expansion would bring countries into NATO that are in an unstable region of Europe.
Some believe that the geographic location of central and east European candidate
states for NATO membership gives them a potential strategic vulnerability should
instability in Russia grow and an aggressive regime come to power in Moscow. The
several years of wrangling among alliance members over how to respond to Bosnia
has led some Europeans to ask whether U.S. and European interests may be
diverging. A senior French official, for example, has said that “in the management of
post-Cold War crises,... a priority for the Europeans may not be a priority” for the
United States. Some allies are hesitant to view NATO’s commitment to implement
the Dayton accords as a test case for the alliance, in part because there is no alliance
consensus over any future commitment to undertake such a mission should ethnic
violence erupt elsewhere in Europe, in part due to concern that the Bosnian conflict
could reignite should NATO forces leave before peace is secured. Others believe that
bringing peace to Bosnia is critical to the alliance’s credibility and relevance. In this
view, NATO could not maintain its importance to European security if it stood by
while a small European power (Serbia) massacred thousands of unarmed civilians in
full view of the world.
The success or failure of efforts to bring peace to Bosnia is affecting the
enlargement debate. Some allies see Bosnia as a test case for the Administration’s and
NATO’s commitment and capacity to build stability in central and eastern Europe.
Some Members of Congress have said that the allies must shoulder a greater share of
the burden in Bosnia to demonstrate their willingness to assume new responsibilities
in Europe.
Position of the Clinton Administration
The Clinton Administration proposed expansion of the alliance at the January
1994 NATO summit. Administration officials believe expansion could protect a range
of U.S. interests, including the strengthening of nations that share the U.S. belief in
democracy; the development of free-market economies open to U.S. investment and
trade; the securing of allies willing to share in efforts on a range of global issues; and
preservation of a Europe free of the domination of any one power. On October 22,2

1996, President Clinton called for the admittance to NATO of new members by 1999.

On June 12, 1997, the President named Poland, Hungary, and the Czech Republic as
the United States’ 3 candidates for membership. On July 8, 1997, at the Madrid
summit, NATO named these three countries as candidates.
The NATO Enlargement Study. The Administration sought a clear decision
and direct steps to expand the alliance at the January 1994 NATO summit. On3
September 20, 1995, NATO announced the findings of the study. The study listed
general criteria (democratic structures, a free market economy, respect for human
rights) necessary in prospective members. New members must accept the full range
of NATO responsibilities, such as building a military able to contribute to collective

defense, providing humanitarian assistance and undertaking peacekeeping missions.
The study did not state that new members must enter NATO’s integrated military
command; the United States has contended that NATO should require all new
members to be within the integrated military command, in order to minimize the
ability of states to except themselves from duties required of others. The study
promised new members a guarantee of protection by NATO’s strategic nuclear forces.
Finally, the study saw no near-term need for basing nuclear weapons or other member
states’ conventional forces on the territory of new members, but left the option of
doing so “when and if appropriate.” It did state that placement of NATO
headquarters on new members’ territory, pre-positioning of materiel there, and
frequent training and exercise by NATO forces would likely be necessary “to
demonstrate NATO’s commitment to collective defense” and to become “familiar
with terrain and conditions.”
The Final Communiqué of the December 10, 1996 NATO Ministerial noted that
NATO has “no intention, no plan, and no reason to deploy nuclear weapons on the
territory of new members....”
Next Steps. On Dec. 16, 1997, in Brussels, NATO foreign ministers signed three
Protocols to the Washington Treaty ; the Protocols are the legal instruments on which
current member parliaments voted in deciding to admit the candidate states. The
Senate approved the Resolution of Ratification approving the Protocols on April 30,
1998, by a vote of 80-19. The President signed the instrument of ratification on May

22, 1998. On March 12, 1999, the foreign ministers of Poland, the Czech Republic,4

and Hungary deposited the instruments of ratification with the United States
Government in a ceremony in Independence, Mo.; this act marked the three countries’
formal adherence to the alliance. NATO decided to bring them into the alliance in
advance of the April 1999 summit in order to have them approve the final draft of the
alliance’s new Strategic Concept before its adoption at the summit. On June 30,
1999, Secretary of Defense Cohen discouraged belief that a second round of
enlargement might take place in the near future. “The door is open,” he said, “but at
the top of a steep stairwell.”
At the NATO summit in Washington on April 23-25, 1999, the allies did not
invite new members, but did keep the door open for future candidate states. The
announced a multi-step program which candidates could follow to enhance their
militaries and their civil-military relations to bring them in line with NATO standards.
Such steps are intended to strengthen the candidacies of a number of states.
Privately, representatives of some countries acknowledged that the manner in
which the crisis in Kosovo is resolved will affect a possible second round of
enlargement. The failure of the Europeans thus far to produce a force able to bear the
brunt of the responsibility in Kosovo, and the failure of the alliance to defeat
Yugoslavia in a timely fashion, have raised questions about NATO’s future. Some
allies believe that issues such as mobility of forces and responsibility for out-of-area
missions must first be resolved before enlargement is again considered.

97-666. July 1, 1997.

Partnership for Peace. The Administration’s Partnership for Peace program
was adopted at the January 10-11, 1994 NATO summit. PFP provides a framework
for NATO’s evaluation of states that are considered to be candidates for alliance
membership. PFP is intended to assist a state establish civilian control over its
military; develop “transparent” defense budgets that outline military capabilities to its
public and to its neighbors; learn new military doctrine; and work with NATO states
to develop specific capabilities, such as peacekeeping. Since 1994, many PFP states,
including Russia, have held joint training exercises with NATO states, and some are
participating in the SFOR mission in Bosnia. The alliance intends to enhance PFP for
those states still seeking membership.
Congressional Action
The omnibus appropriations measure (title XXVII of P.L. 105-277; H.R. 4328)
contains the European Security Act of 1998. The Act endorses NATO enlargement;
urges that the door to alliance membership be kept open should a first round of
enlargement occur; specifically urges consideration of the Baltic states, Bulgaria, and
Romania, should they meet necessary criteria; and outlines recommendations for arms
control negotiations that affect new and current members. The legislation refers to
the NATO Participation Act of 1994 (Title II of P.L. 103-447) for a description of
criteria for membership. P.L. 103-447 states that candidate states must make
significant progress towards establishing democratic institutions and free market
structures, as well as well-developed civilian control of the military and a policy of
prohibiting transfer of arms to countries supporting terrorism. The President signed
H.R. 4328 into law on Oct. 21, 1998.
The European Security Act states that no commitments be made to Russia
concerning conventional and nuclear force deployments having “the effect of
extending rights or imposing responsibilities” on new members different from
commitments to current members. In addition, NATO should make no commitments
limiting the construction of defense infrastructure or deployment of reinforcements
on new member state’s territory. It asks that these considerations on conventional
forces be reflected in the re-negotiation of the Treaty on Conventional Forces in
Europe (CFE) now under way. The legislation also states that no international
organization and no non-alliance member should gain the authority “to review, delay,
veto, or otherwise impede deliberations and decisions” of NATO’s decision-making
body, the North Atlantic Council. The legislation states that a NATO- Russia
agreement should include commitments by Moscow to delineate its borders with its
neighbors, station forces on other states’ territories only with their permission, and
agree to reduce nuclear and conventional forces in Kaliningrad, a part of Russia that
borders Poland and Lithuania.
The European Security Act addresses the issue of burdensharing in NATO
enlargement. It states that “the United States already pays more than a proportionate
share of the costs of the common defense of Europe and should obtain, in advance,

agreement on an equitable distribution of the cost of NATO enlargement to ensure
that the United States does not continue to bear a disproportionate burden.”
Program of Assistance. The European Security Act authorizes the expenditure
of funds for NATO’s Partnership for Peace program to eligible states (under P.L.
103-447). The bill urges funds for the Regional Airspace Initiative (RAI) and the PFP
Information Management System (PIMS). RAI is designed to develop civilian and
military airspace regimes fully compatible with west European civilian airspace
organizations. Most central European states have committed funds to implement such
systems, leveraged in part by a U.S. offer to provide Foreign Military Financing for
construction of air operations centers. PIMS is a computer network that links PfP
capitals with U.S. facilities and the Partnership Coordination Cell at SHAPE
headquarters in Mons, Belgium. Close communication between NATO and
Partnership countries is considered by NATO officials as an important practical means
to coordinate exercise planning via an electronics link, and thereby reduce the need
for large (and expensive) conferences among military officials.5
Senate Debate
Resolution of Ratification and Amendments. On March 3, 1998, by a vote
of 16-2, the Senate Foreign Relations Committee approved a Resolution of
Ratification, and sent it to the full Senate in Exec. Rpt. 105-14. The Resolution
describes U.S. membership in NATO as a “vital national security interest”; states that
the candidate states have democratic governments willing to meet the requirements
of membership; underscores that collective defense is the alliance’s “core purpose”;
notes emerging threats such as proliferation and ethnic conflict; encourages European
Union expansion to promote stability; and urges an “open door” to future enlargement
of the alliance. The document also addresses Russia’s relationship with NATO. It
calls the North Atlantic Council (NAC) the “supreme decision-making body of
NATO,” not subject to review by the NATO-Russia Permanent Joint Council or any
non-member state or organization, such as the UN. The Resolution requires that, 180
days after its adoption, the President submit a report to the Senate on the Strategic
Concept, as well as on the progress and timetable for NATO members meeting their
force goals.
Senators Warner and Moynihan proposed an amendment requiring that the
candidate states’ admission to NATO be deferred until those states are admitted to
the European Union. Sen. Moynihan said that the three countries “face no security
threats, so strengthening their economies and democratic institutions should be their
first priority....[The 3 countries should] “concentrate their full resources on economic
modernization, rather than diverting precious resources to military expenditures,” and
EU membership will assist them in accomplishing this objective. (CR, March 3, 1998).
Among the counter-arguments, Sen. Biden contended that because the United States
is not a member of the EU, the United States would effectively be putting a key
element of its future security in the hands of European decision-makers. He endorsed

Paul E. Gallis, Richard Grimmett, and Larry Q. Nowels. CRS Report 97-531. May 9, 1997.

EU enlargement, but said that the Senate should not wait for an EU decision that
could be many years in coming. (CR, March 18, 1998) The amendment was defeated.
Sen. Warner has also proposed a condition to the Resolution of Ratification that
would place a moratorium on further expansion of the alliance “for a period of at least
three years” from the date of entry of Poland, Hungary, and the Czech Republic. He
contended that a period of time should pass for NATO to consider the true costs of
enlargement, how quickly the three countries could meet NATO interoperability
standards, and judge the level of stability in Central Europe and Russia. Opponents
of the amendment did not wish to place restrictions on the freedom of action of a
future Senate, and contended that the costs of enlargement are sufficiently well
known. (CR, March 19, 1998) The amendment failed.
Sen. Harkin proposed an amendment that would have redefined the “NATO
common-funded budget,” of which all member states pay a share. The amendment
would have added FMF, IMET, and the costs of excess defense articles transferred
to NATO states as part of the total U.S. share of the common budget. Senator
Harkin contended that such transfers amount to “bilateral subsidies” adding to the
U.S. costs of enlargement. Opponents of the amendment contended that elements6
of such assistance packages often have little to do with enlargement, and assist
countries already in the alliance. The amendment failed.
Senator Kyl offered an amendment that called on the Administration to negotiate
a Strategic Concept that would clarify NATO’s post-Cold War strategy, underscoring
NATO’s role as a military rather than a political or economic alliance, emphasizing
its role as a collective defense organization, and listing its threats as being, among
others, a revived “hegemonic power,” rogue nations seeking weapons of mass
destruction, and ethnic and religious conflict. The amendment called upon allied
countries to develop lighter, more mobile forces able to move long distances quickly
to join U.S. forces in fighting a high-intensity conflict. (CR, April 27, 1998) The
amendment passed.
Assessment of the Debate
NATO’s Mission
What is NATO’s purpose? How would U.S. security interests be affected by
enlargement? These questions are at the heart of the alliance debate over
enlargement. During the Cold War era, the NATO Treaty’s Article V commitment7
to collective defense was the core mission of the alliance. By the 1970s and 1980s,
over 300,000 U.S. troops were stationed in NATO Europe. A heavy conventional
force presence was viewed by political and military leaders of NATO states as an

important instrument to put off the moment, should a conflict begin, when the West
would have to make a decision to resort to nuclear forces; in addition, the very
engagement of large-scale U.S. conventional forces sent a signal to the Soviets that
the United States would use its nuclear forces to prevent a defeat of allied states. The
United States stationed nuclear systems in Europe, and backed its commitment to the
allies’ security by strategic nuclear systems as well. The presence of U.S. conventional
forces in Europe and the U.S. nuclear guarantee sent a strong political message that
the fate of the European allies was tightly linked to that of the United States.
The U.S. conventional and nuclear presence gave a stronger message of
guaranteed assistance in the event of conflict than a literal reading of Article V
implies. Article V notes that “an armed attack against one or more [allies] shall be
considered an attack against them all.” But additional language makes clear that the
commitment to come to the assistance of a Treaty party under attack is not
unconditional. Rather, it states that each signatory will assist the ally under attack
with “such action it deems necessary, including the use of armed force....” Such
language could mean that an ally would provide no assistance, or political support
only, or, of course, full military engagement.8
U.S. conventional forces in NATO Europe are declining, and now stand at
approximately 109,000. Few U.S. nuclear systems are now in Europe; Intermediate
Nuclear Forces (INF) were eliminated under the 1988 INF Treaty, tactical nuclear
weapons have been withdrawn, and only a reduced number of gravity bombs remains.
In 1991, NATO declared that the (then) Soviet Union was no longer an “enemy” of
NATO. In NATO’s 1991 “Strategic Concept”, the alliance signaled its intention to
move towards lighter, more mobile forces for power projection in central Europe to
develop an improved capability for crisis management and such missions as
peacekeeping and peace enforcement. Some countries, such as the United States,
France, the Netherlands, and Britain are in the process of reshaping their forces to
accomplish such missions, a reflection of dramatically improved East-West relations
since the end of the Cold War. Moreover, given that Russian military forces are
suffering from severe budgetary constraints, conscription shortfalls, sharp
deterioration in morale and readiness, and uncertain leadership, the threat posed by
Russia has markedly declined.
The Senate Foreign Relations Committee Report on enlargement endorsed
efforts to combat new threats to European security, but added that “no consensus
exists in the Committee in support of a broader mission for NATO.” It endorsed
territorial defense (Article V) as NATO’s core purpose, and insisted that other
missions, such as crisis management and peace operations, not be elevated above
territorial defense.
Senator Lugar has called for consideration of the idea of “double enlargement”
— enlargement in geographic terms, but enlargement also in the sense of NATO
taking on new missions that will give the alliance new and clear purpose. He has
specifically mentioned crisis management and peacekeeping as such missions to which

new members might contribute and which might also serve to enhance European
security. (May 1996.)
Other members have raised concerns about enlargement. Senator Stevens, in
hearings before the Senate Armed Services Committee on Oct. 21, 1997, expressed
doubts about the accuracy of the Administration’s cost study of enlargement, and said
that existing evidence indicates that the costs — and the U.S. share of those costs —
may be higher. He believes that U.S. forces could serve U.S. interests better in other
parts of the world than Europe, and that U.S. budgetary expenditures for enlargement
should be allocated for modernization and readiness of U.S. forces. Chairman of the
Joint Chiefs of Staff Gen. Shelton responded that adding the 3 candidate states to
NATO would, in his view, improve readiness of the alliance, and serve to protect U.S.
interests by enhancing stability on the continent, deterring transnational threats such
as terrorism and the proliferation of weapons of mass destruction, and guarding
against a potential revived Russian threat.
NATO’s mission of collective defense remains important to member states
because of a concern that Russia, still armed with nuclear weapons, might one day
become more unstable and aggressive, and a direct threat to its neighbors.
Representatives of several central European states interviewed recently expressed
concern over an eventual Russian threat, and stated that the Article V commitment
is the principal reason for their desire to join the alliance. While many Administration
officials emphasize the importance of Article V, they also note that U.S. and allied
defense spending is declining, in response to public demand as well as to a perceived
declining Russian threat. According to U.S. General Wesley Clark (SACEUR), in the
period 1990-96, NATO defense budgets collectively declined 15%, land forces 50%,
naval forces 40%, and air forces 30%, prompting some observers to question whether
NATO forces could defend Poland, Hungary, and the Czech Republic in the event of
a conflict?
The state of Russian conventional forces would make it difficult to mount a
credible attack in central Europe, much less a surprise attack. Many U.S. and allied
officials believe that Russian conventional forces continue to decline; in May 1997,
President Yeltsin called for a further 30% reduction in his country’s defense budget.
Today, Russia spends 5% of its shrunken GDP on defense; Yeltsin said on May 23,
1997, that he intends for the figure to drop to 3 to 3.5% by the year 2000. Some
observers believe that the Russian government is cannibalizing its defense budget to
free funds for internal security forces, reflecting an overriding concern about internal
unrest. On Oct. 7, 1998, Yuri Maslyukov, then the communist deputy prime minister,
said that Russia could no longer afford its large strategic nuclear force, and should
reduce the force to a few hundred warheads by 2010. According to press reports, the
Russian general staff reported to Yeltsin in February 1999 that financial constraints
will require that military forces be reduced to 550,000-600,000 during the next two
years, a figure half that of current levels.
A meaningful Russian conventional threat to central European states is plausible
only at a future moment, when Russia’s economy stabilizes, greater defense
expenditures are taking place, and a leadership in power intending to seek territorial
gains or exert greater influence over neighboring states. In such circumstances, in
purely military terms, some states seeking NATO membership could prove difficult

to defend. Poland’s terrain is largely flat, making defense of its territory questionable
using conventional forces. A contrasting view holds that Poland could offer tactical
advantages to the alliance in the event of a conflict involving heavy armor. NATO9
force-projection capabilities and many years of training for “deep battle” — moving
highly maneuverable armored forces long distances and limiting an adversary’s ability
to do the same — would put allied forces at an advantage, in this view. Russian
armored forces would have to traverse considerable territory to reach Poland, an
undertaking that would require a long and potentially vulnerable logistics train. A
possible weakness in this argument is the relative lack of forest in Poland to provide
cover for NATO’s armored forces. Another weakness is that Russia might heighten
its considerable influence over Belarus and station armored forces on Belarusian soil,
a measure that would enhance Russian logistics. The Baltic states, hinged against
Russian territory and difficult to supply, are, in the view of many NATO military
officials, in a starkly more disadvantageous strategic position (interviews).
Secretary of Defense Cohen believes that important U.S. interests could be
served by enlargement. Enlargement, he said, could dampen nationalism and ethnic
tensions by bringing new member states into NATO’s security framework. The
re-nationalization of defense, with a country obtaining weapons of mass destruction,
“arming itself against an enemy, real or perceived,” could be more easily averted by
enlargement, and a war into which NATO might be drawn could be avoided.
The Clinton Administration has begun to cast NATO’s mission in a changing
light. Citing Russia’s military decline, U.S. officials note that new risks such as
nuclear proliferation could trigger an Article V (collective defense) situation. In this
view, any new alliance members must understand that they would be expected to help
prevent proliferation, and to assume responsibility in dealing with new nuclear powers
that might become a threat. This view also supplies part of the rationale for NATO
moving from a heavy, armored positional defense in central Europe (one geared
against a Russian attack) and towards lighter forces for power projection, able to
move quickly to address a distant crisis. Not all NATO members accept that the
proliferation threat might be dealt with through possible military action, nor that it
should be classed as an Article V contingency. The French government, for example,
believes that NATO should emphasize political steps to curb proliferation and other
potential new threats. The vagueness on this point of the revised Strategic Concept,
agreed at the April 1999 NATO summit, reflects the differences over this issue.
The inability of several key European allies to move forces rapidly into the
Yugoslav theater during the early days of the Kosovo conflict underscored important
alliance weaknesses in the area of lift and general mobility of forces. In addition, the
bulk of the air strikes have been undertaken by U.S. airplanes, raising an issue of
burdensharing. Resolution of the conflict is virtually certain to provide a moment for
allied states to reassess their contribution to the alliance, and the future needs of their
forces, issues that were raised in the United States during the enlargement debate,
particularly the discussion of the Kyl amendment.

Challenges for Defense Planning. Rand, 1994, pp. 451-476.

Estimated Costs of Enlargement and Burdensharing
In March 1996, CBO issued a report assessing costs of enlargement under five
possible options, ranging from assisting a new member engaged in a border skirmish
or a conflict with a regional power, to the permanent stationing of the forces and
equipment of current member states on the territory of new members to prepare for
a broader conflict. The study assumes that Poland, Hungary, the Czech Republic, and
Slovakia would be the initial new members and that costs would be spread over 15
years. Costs at the low end (for option 1) would be $60.6 billion, with the U.S. share
being $4.8 billion, and at the high end (for option 5) $125 billion, with the U.S. share
being $18.9 billion.10
A fall 1996 RAND study estimated that expansion (to include Poland, the Czech
Republic, Hungary, and Slovakia, over 10-15 years) would cost $10-20 billion if new
member states alone modernized their militaries; $30-52 billion if current members
undertook preparations to deploy 10-15 divisions and 10 fighter wings on the territory
of new members; and $55-110 billion for forward deployment of current members’
forces on the territory of new members in contemplation of a resurgent threat from
the east.
The Administration’s February 1997 Report to Congress estimated that the cost
of enlargement would be $27-35 billion between 1997-2009. The emphasis for
prospective new members would be on enhancing “interoperability” (such as
developing air defense and command-and-control compatible with those of current
NATO members, and training to learn the alliance’s operational concepts),
modernizing and downsizing their militaries, and upgrading facilities such as airfields
and roads for receiving reinforcements from current member states. Current members
would be expected to utilize defense expenditures to enhance their capacity to reach
the new member states and potential regions of crisis with lighter, more mobile forces
than those of the Cold War years. (In July 1997, USACOM commander Gen. John
Sheehan criticized the allies for leaving it to the United States to develop the lift and
command-and-control assets necessary for NATO’s new missions.) Over 12 years,
the estimated annual costs to the United States would be $150-200 million; $800-100
million to new member states; and $600-800 million to current members. The report
notes that enhanced needs for collective defense could drive the costs up.
In August 1997 GAO, at the request of the Chairman and Ranking Member of
the House International Relations Committee, issued a study of the Administration’s
Report to Congress. GAO found that the Administration’s assumptions were
“generally reasonable,” citing in particular the Administration’s assessment of a
low-threat environment. However, GAO noted that the Administration supplied few
documents supporting determination of costs, and relied on “expert guesses” due to
unavailability of hard data. For these reasons, costs might be “substantially higher or
lower” than the Administration’s estimate.11

On December 2, 1997, NATO approved a report with estimated costs of
enlargement that are sharply lower than previous estimates. The report’s findings
were released, but the actual report remains classified. The report stated that the
costs of enlargement to current allies over 10 years should be $1.3 - 1.5 billion.
NATO and U.S. officials said that the lower estimate could be explained by the
discovery that candidate states’ infrastructure was in much better condition than
previously thought. At the same time, a classified NATO report that provides a
preliminary evaluation of the candidate states’ DPQ’s was leaked to the press. It
reportedly states that in fact the infrastructure of the candidate states is in very poor
condition, that the equipment, for example, of the Czech army is approaching
obsolescence, and that the costs for enlargement could be considerable.
The European Allies
The European allies evince a spectrum of views on the issue of enlargement. 12
At the Madrid summit, a consensus settled on naming Poland, the Czech Republic,
and Hungary as candidate states. In the summit communiqué, the allies agreed that
enlargement would enhance stability. A number of countries, led by France,
championed Romania’s candidacy; some members, led by Italy, supported Slovenia’s
candidacy. The United States opposed naming either of the two states. Member
states must unanimously agree, through their constitutional processes, to amend the
North Atlantic Treaty to admit the 3 candidate states.
On February 2, 1998, Canada agreed to admit the three states; on the following
day, Denmark followed suit. On March 3, the Norwegian parliament approved the
candidate states’ entry, as did Iceland on March 19 and the German Bundestag on
March 26. On May 14, Greece approved enlargement, as did Luxembourg on May
24; on June 23 the Italian parliament followed suit. France and Britain approved the
three states in July. On August 25, Spain gave its approval. In August, Belgium also
approved the three states, as did Portugal on September 16. On October 21, Turkey
gave its consent. On December 2, the Netherlands’ parliament approved enlargement.
All member states have now approved expansion of the alliance, as required by the
treaty for the candidate states’ admission.
Elements of doubt about enlargement and its effect on strategic issues remain
evident. These sentiments will affect possible future rounds of enlargement. Some
officials in NATO countries believe that different security interests [in NATO] are
being regionalized, with the implication that the addition of more states would lead
to further dilution of consensus in the alliance. This view is widely heard in allied
Defense ministries, where a belief remains that the impulse for divergent responses of
member states to the conflict in Bosnia would only be exacerbated when new states
join and new ethnic conflicts or regional crises to emerge. Popular support in
Hungary and the Czech Republic is lacking for NATO’s air campaign in Yugoslavia
(as well as some states that are not new members). Some Italian officials privately13
express doubt that the interests of southern European members of NATO would be

served by the potential entry of northern European countries such as the Baltic states;
in contrast, the Nordic countries opposed the inclusion of Romania and Slovenia,
backed by Italy and other members, as not serving the interest of northern European
Allied governments were reluctant to share in the costs of enlargement as initially
estimated by the Clinton Administration, in part because their publics desire declining
defense budgets, in part because of competing budgetary priorities. President Chirac
has been the most vocal among leaders of allied governments. On July 11, 1997, he
said, “We have adopted a very simple position: Enlargement must not cost anything
in net terms” because there is no threat. “In reality, NATO is a peacekeeping body,
a crisis management system, and accordingly can afford much lighter resources in
terms of both equipment and infrastructure... France...has no intention of increasing
its contribution to NATO to cover enlargement.” (Document provided by the French
Embassy.) The British government initially contended that the Administration’s cost
estimates were too high and that the Administration was “using arguments about
enlargement to leverage a better performance [from allies] on force goals.” On Oct.
21, 1997, however, British Defense Secretary George Robertson said that “if
additional spending is required, Britain will pay its share.” The December 1997
NATO cost study of enlargement was endorsed by all member governments, and
presumably obligates them politically to share the costs provided in that estimate.
Candidates for NATO Membership
The 1994 NATO Participation Act, as noted, mentions criteria necessary for
NATO membership. The North Atlantic Treaty does not establish explicit criteria for
entry. The preamble to the Treaty does state that member governments are “founded
on the principles of democracy, individual liberty and the rule of law.” Article I
obligates member states to refrain from the use of force, unless attacked, to resolve
international disputes. Article II commits them to “strengthening their free
institutions.” Article III commits them to “maintain and develop their individual and
collective capacity to resist armed attack.” Article X states that, by unanimous
agreement, current members may admit other states “in a position to further the
principles of this Treaty.” These principles have not always been rigorously applied,
either to applicants or to member states. Portugal became a member in 1949, even
though it had a dictatorial government. Today, some members criticize Turkey for
its repression of the Kurds, or Greece for discrimination against Moslems. Other
members, such as Luxembourg and Iceland, have virtually no military capacity, or
have sharply declining defense budgets and marginally effective forces.
Poland, the Czech Republic, and Hungary have all had elections judged free and
fair by international bodies since the fall of the Berlin Wall in 1989. Each has made14
strong progress towards developing free market economies, and is attracting western
investment, and each is a candidate for European Union membership. At the same
time, their militaries suffer from significant deficiencies. Their equipment is aging, and
their armed forces remain top-heavy with officers. Their fighter pilots average 40-60

hours in the air a year; the NATO standard is 180 hours. All three are in the process
of learning NATO training and practices, in part through participation in Partnership
for Peace. Of particular importance are lack of English language skills among officers
and a lack of a strong sense of initiative among both officers and non-commissioned
officers. Secretary Cohen has stressed the need for the development of a strong corps
of NCOs in each candidate state. The three countries have established firm civilian
control of their militaries, and a total of 1500 of their troops are participating in the
Stabilization Force (SFOR). In addition, all three states endorsed U.N. Res. 1199,15
which approves the possible use of force against Yugoslavia for its continued
repression of Kosovo.
In February 1999 the three candidate states unveiled new military-civilian air
navigation networks, a key part of NATO military infrastructure that assists in the
control and tracking of air traffic. The state-of-the-art technologies replaced dated
Warsaw Pact systems.
Poland. Poland’s defense budget stands at approximately 2.8% of GDP, above
the average (2.1%; the U.S. percentage is approximately 3.8%) for NATO members.
Poland intends to increase its defense budget to 3% of GDP in order to bring its
military closer to NATO standards. The country continues a Warsaw Pact practice
of having a top-heavy officer corps, but intends to cut personnel in order to streamline
its forces. Some U.S. officers believe that Poland spends too much money preserving
outmoded facilities and insufficient amounts on training and modern equipment.
Deputy Defense Minister Korkoszka has said that Poland must “obtain combat
aircraft, ground-to-air, sea-to-sea, and air-to-air missiles, submarines, and certain
types of artillery.” Poland’s governing elite and population strongly support entry
into NATO. Poland’s economy continues to expand, and is expected to grow in 1999
at 5.1%, after a 1998 GDP growth rate of 5.2%. Its western economic orientation
continues: in 1998, 64% of its exports have gone to the EU, and only 8% to Russia.
The Polish government endorsed NATO’s decision to launch a bombing
campaign against Yugoslavia on March 24, 1999. It has sent a force of 140 men to
Albania to guard NATO commanders, and has agreed to take Kosovar refugees.
Hungary. On Nov. 16, 1997, with a relatively low turnout of 49%, the
Hungarians endorsed NATO membership through a referendum; 85% of those voting
cast ballots supporting membership. Hungary’s political elite strongly supports
membership. Hungary’s defense spending had been declining, reaching 1.5% of GDP
in 1996. It now stands at 1.8% of GDP. U.S. officers give Hungary high marks for
assistance provided at the military base in Taszar, which the United States leases for
some of its operations in Bosnia. Hungary’s armed forces are restructuring, with an
all-volunteer force of 50,000 (down from 140,000 in the Warsaw Pact era) as the
government’s goal. Hungary’s top-heavy general staff has already been sharply
trimmed, and a more decentralized command system with a cadre of career NCOs on
the NATO model is being developed. Its air force is small and in need of
modernization, but the government is following NATO recommendations and

concentrating first upon acquisition of modern radar and communications equipment.
In July 1998, the center-right coalition of Victor Orban came to power and said that
during its tenure it is unlikely to purchase high-performance aircraft.
The conflict over Kosovo has presented difficult problems for the Hungarian
government. Hungary is the only NATO member that borders Yugoslavia; its
relatively flat border intersection with Yugoslavia makes it an obvious route for a
possible invasion of Yugoslavia, should NATO decide upon that course. At the same
time, approximately 300,000 ethnic Hungarians live in Vojvodina, the northern part
of Yugoslavia. It is possible that an imminent ground invasion would see Serb
violence against the Hungarian minority in an effort to drive out an element of the
population that Yugoslav President Slobdan Milosevic may believe has divided
loyalties. For that reason, the Hungarian government’s interest has been to ensure
calm in Vojvodina. A majority of the Hungarian population, as of late May 1999,
opposes NATO’s air campaign. Hungary has urged its NATO allies not to bomb
targets in northern Yugoslavia, but NATO warplanes have repeatedly struck the
region, especially a strategically important railhead and military site near the town of
Sombor. The Hungarian government has agreed to allow NATO aircraft to undertake
missions from its airfields, but the Hungarian foreign minister said on April 29, 1999
that “for now and forever” his government would not allow a ground offensive to
begin on Hungarian soil.
Czech Republic. On July 17, 1998, Milos Zeman, a Social Democrat, was
appointed prime minister of a minority government, dependent for its survival upon
support in parliament from the defeated Civic Democrats (ODS). The Social
Democrats support Czech membership in NATO. The previous government, which
also supported NATO membership, did little to promote it publicly, in part due to the
expected expense of membership and controversy over increased defense
expenditures. The Czech military, in the early stages of modernization, remains
unpopular among the citizenry due to its legacy of repression during the Cold War;
additional defense expenditures are therefore unpopular. The Czech defense budget
is 1.8% of GDP. The government has pledged to reach a figure of 2% in 2000. The
Czech Republic has 60,000 men in its armed forces; much of the top-heavy, Warsaw-
Pact trained officer corps has been pared. Some U.S. officials have criticized the
Czech Republic’s efforts to modernize and re-train its forces.
The Czech political elite strongly supports entry into NATO. Opinion polls
indicate that popular support is unsteady, but rising. A USIA poll of October 1997
found that 59% of the population support NATO membership; however, Czech polls
of the same month variously indicated that support stood at figures from 35% to 47%.
A Czech poll of February 1998, like the October 1997 poll, found that 59% of those
responding support NATO membership. Polls are conducted by telephone; the legacy
of the Cold War era may make respondents reluctant to express an opinion, thereby
causing different results in each poll. The Czech population has had negative
experiences with alliances during this century: Czechoslovakia’s allies in the 1930s
failed to come to its defense in the face of German aggression; the Russian-led
Warsaw Pact imposed a harsh authoritarian regime. For these reasons, many Czechs
continue to distrust their military and military organizations in general. At the same
time, the Czech Republic has a highly educated population clearly dedicated to

democratic ideals. Some observers expect public opinion to embrace NATO
membership more firmly as the debate in the country progresses.
The Czech governing elite has given mixed messages over the conflict in
Kosovo. President Havel has strongly supported the NATO air campaign. In
contrast, Prime Minister Zeman initially distanced himself from NATO’s decision to
go to war, saying that the decision was made before the Czech Republic joined NATO
on March 12, 1999. In fact, NATO made a final decision on March 23. The
government has since begun publicly to support the NATO air campaign. It allows
U.S. KC-135 (refuelling aircraft) to use its airfields, and NATO men and equipment
to transit Czech territory. The Czech Army has sent a field hospital to Macedonia.
Russia describes potential NATO expansion as a threat to its well-being.16
Russian officials frequently note that invasions by European powers of Russian
territory since the 18th century have come across the Polish plain. On Oct. 25, 1996,
the Duma passed a resolution opposing enlargement by a vote of 307-0. Russian
officials contend that the “Two plus Four Treaty” of 1991 uniting Germany prohibits
the expansion of NATO beyond eastern Germany. The Treaty does not in fact
contain such language, nor imply such an agreement. However, Jack Matlock,
ambassador to the Soviet Union in 1991, stated that the United States made a verbal,
but legally non-binding, commitment not to enlarge the alliance at the Two plus Four
The collapse of the Russian economy has reduced Russia’s weight in
international affairs. Some observers express concern that political instability in
Russia could lead to less central control over nuclear weapons, or efforts by some
republics to gain independence, preparing the ground for a more authoritarian,
nationalist leader. Sharp disagreements with NATO over the conflict in Kosovo have
also adversely affected relations. Russian officials contend that NATO is acting
outside the auspices of international law by attacking Yugoslavia over what Moscow
views as issues having to do with Yugoslav sovereignty. NATO has sought to use
Russia as an intermediary with Belgrade, but NATO’s objectives and Russia’s
objectives for resolution of the Kosovo conflict remain different on key points.
The Founding Act. On September 6, 1996, former Secretary Christopher
endorsed a French plan for negotiating a “charter” between NATO and Russia.
NATO and Russia signed the document, to be called “the Founding Act,” on May 27,
1997, in Paris. The Founding Act touches upon several issues addressed in the
European Security Act. H.R. 1757 requires that no commitments be made to Russia
concerning nuclear and conventional forces that would place new member states in
a category different from that of current members. The Founding Act restates a
current NATO position that the alliance has “no intention, no plan, and no reason” in
the foreseeable future to station nuclear weapons or nuclear weapons storage sites on
new members’ soil, but it does not preclude NATO from doing so should the need

April 14, 1998.

arise. In addition, the Founding Act states that NATO may maintain military
infrastructure on the soil of new members “adequate” to assure their protection under
Article V of the NATO Treaty. NATO pledges “in the current and foreseeable
security environment” not to station “substantial combat forces” on new members’
territory, but at the same time underscores the intention to increase interoperability,
integration, and reinforcement capabilities with the new member states.17
The European Security Act states that the Administration must not give any state
or international organization a veto or right of review in NATO decisionmaking. The
Founding Act establishes a Permanent Joint Council between NATO and Russia to
undertake consultations on matters of mutual interest, such as peacekeeping, nuclear
and biological weapons proliferation, terrorism, and drugs, but states that “the
consultations will not extend to internal matters of either NATO, NATO members
states, or Russia... .” At the April 1997 Senate Armed Services Committee hearing,
Secretary of State Albright told Senator McCain that the NATO-Russia Permanent
Joint Council would not be a decision-making forum, and that Russia would have no
influence over issues such as NATO’s defense posture. He asked whether Moscow
would be obligated to discuss in the Council such issues as Russia’s evolving union
with Belarus, its policies towards the Baltic states, or the deployment of Russian
peacekeeping forces in the Caucuses. Secretary Albright responded that such issues
are discussed bilaterally with Moscow, and would not be addressed in the Council.
With some exceptions, the Permanent Joint Council has met monthly since
September 1997. NATO has sought a narrow agenda, Russia a broader one. For
example, Russian officials have complained that they had not been adequately
consulted over SFOR’s decision in Bosnia to pursue war criminals, and that such
pursuit went beyond SFOR’s mandate.
Defense Capabilities
Earlier legislation, such as the NATO Enlargement Facilitation Act, encouraged
the Administration to transfer “advanced fighter aircraft” and other weapons systems
to frontline candidate states for membership. Poland and the Czech Republic have
had discussions with the Department of State about acquiring small numbers
(reportedly, less than a dozen) of F-16s and/or F-18s, which are high-performance
combat aircraft. The presence of representatives of U.S. companies that build such
aircraft in the 3 candidate states has become an issue in central Europe, where some
officials and some citizens have complained of pressure to purchase such systems.
Secretary Cohen said on October 9, 1997, that the three countries should concentrate
on making their militaries interoperable with NATO militaries and training their forces
to NATO standards, and that purchase of high-performance aircraft should be
postponed for the “foreseeable future.”

A continued course by these states of democratic practices could allay some
Russian concerns that NATO seeks to build an aggressive defense alliance near its
borders. In contrast, ethnic violence and economic dislocation in central Europe
would raise tensions with Russia and further the cause of those in Russia who believe
that Moscow must play a major, perhaps decisive role in determining the future of the
region. The outcome of the Kosovo conflict may affect the future course of
expansion. The United States is bearing the brunt of the military effort there. It is
possible that issues such as burdensharing and the need for the European allies to
develop more mobile forces to fight in out-of-area engagements will push enlargement
off the near-term agenda. At the same time, an opposing sentiment may emerge that
ethnic conflicts, such as the one in Kosovo, underscore the need for alliance expansion
to accelerate the development of stability.
NATO expansion would most likely enhance security in Europe if it occurred in
a period when the conditions that led to the Article V commitment to mutual defense
had receded, and minimal criteria for improvements in central and eastern Europe’s
defense posture were required. Politically, the mission of collective defense co-exists
uneasily with NATO’s intention to expand to the east, which Russia does not perceive
as a defensive initiative. The Russian political elite continues to view enlargement as
an encroachment on Russia’s traditional sphere of influence. In contrast, supporters
of enlargement stress NATO’s posture as a defensive alliance, and underscore the
right of candidate states to seek membership in political and security institutions that
enhance prospects for international stability.
