When in 1990 U.S. Secretary of State James Baker assured Russian President Mikhail Gorbachev that the North Atlantic Treaty Organization would not expand one inch eastward after German reunification, he was not alone in making that commitment. Documents declassified a few years ago establish that the same pledge was also made by President George H.W. Bush, West German Foreign Minister Hans-Dietrich Genscher, West German Chancellor Helmut Kohl, CIA Director Robert Gates, French President Francois Mitterrand, British Prime Minister Margaret Thatcher, British Foreign Secretary Douglas Hurd, British Prime Minister John Major, and NATO Secretary General Manfred Woerner.
