Washington D.C., December 12, 2017 – U.S. Secretary of State James Baker’s famous “not one inch eastward” assurance about NATO expansion in his meeting with Soviet leader Mikhail Gorbachev on February 9, 1990, was part of a cascade of assurances about Soviet security given by Western leaders to Gorbachev and other Soviet officials throughout the process of German unification in 1990 and on into 1991, according to declassified U.S., Soviet, German, British and French documents posted today by the National Security Archive at George Washington University (http://nsarchive.gwu.edu).

The documents show that multiple national leaders were considering and rejecting Central and Eastern European membership in NATO as of early 1990 and through 1991, that discussions of NATO in the context of German unification negotiations in 1990 were not at all narrowly limited to the status of East German territory, and that subsequent Soviet and Russian complaints about being misled about NATO expansion were founded in written contemporaneous memcons and telcons at the highest levels.

The documents reinforce former CIA Director Robert Gates’s criticism of “pressing ahead with expansion of NATO eastward [in the 1990s], when Gorbachev and others were led to believe that wouldn’t happen.”[1] The key phrase, buttressed by the documents, is “led to believe.”

President George H.W. Bush had assured Gorbachev during the Malta summit in December 1989 that the U.S. would not take advantage (“I have not jumped up and down on the Berlin Wall”) of the revolutions in Eastern Europe to harm Soviet interests; but neither Bush nor Gorbachev at that point (or for that matter, West German Chancellor Helmut Kohl) expected so soon the collapse of East Germany or the speed of German unification.[2]

The first concrete assurances by Western leaders on NATO began on January 31, 1990, when West German Foreign Minister Hans-Dietrich Genscher opened the bidding with a major public speech at Tutzing, in Bavaria, on German unification. The U.S. Embassy in Bonn (see Document 1) informed Washington that Genscher made clear “that the changes in Eastern Europe and the German unification process must not lead to an ‘impairment of Soviet security interests.’ Therefore, NATO should rule out an ‘expansion of its territory towards the east, i.e. moving it closer to the Soviet borders.’” The Bonn cable also noted Genscher’s proposal to leave the East German territory out of NATO military structures even in a unified Germany in NATO.[3]

This latter idea of special status for the GDR territory was codified in the final German unification treaty signed on September 12, 1990, by the Two-Plus-Four foreign ministers (see Document 25). The former idea about “closer to the Soviet borders” is written down not in treaties but in multiple memoranda of conversation between the Soviets and the highest-level Western interlocutors (Genscher, Kohl, Baker, Gates, Bush, Mitterrand, Thatcher, Major, Woerner, and others) offering assurances throughout 1990 and into 1991 about protecting Soviet security interests and including the USSR in new European security structures.
