Russia in the 90, under Yeltsin rein was weak state went through permanent crisis both economically and politically. In 1991 had come breakthrough when Yanayev's Putch overcome by the Yeltsin's supporters. Even though west countries were deeply convinced at Russia entered right way to the democracy, but in the same moment Russia turned to system based on the oligarchy. This was due to runaway privatization mainly petrol sector. In the mid of 90's Wladimir Putin former KGB officer begun expand own sphere of influences in Russia cooperated with Yeltsin government.
After collapsing of Communist Block in Europe USA's administration begun to launch new order in Europe. The main tool being used to extend its influence in Europe was NATO. In the 90s, just after the fall of communism, the countries of central and eastern Europe received the promise of their inclusion in the structure of NATO in exchange for full support of the US political aspirations. The common belief about the end of the Cold War was very strong in American political circles.
Russia's weakness has been used largely by the US, which increased its manor in Europe to the greatest extent since the beginning of the Cold War. The last European country being included before 90s to NATO was Spain and it was in 1982. Moreover there was a guarantee from US side that NATO will not expand any further than Germany and that was the thing on which Gorbachev based his foreign policy. "The Clinton administration reneged on that commitment when it decided to expand NATO to Eastern Europe". The controversy surrounding this matter abated briefly after the initial round of NATO enlargement in 1997-1999 that led to the admission of the Czech Republic, Hungary, and Poland, but it flared up again in 2001-2002 when NATO prepared to invite several more countries to join, including the three Baltic states, which until August 1991 had been part of the USSR.
