[E]xpanding NATO would be the most fateful error of American policy in the entire post-Cold-War era. Such a decision may be expected to inflame the nationalistic, anti-Western and militaristic tendencies in Russian opinion; to have an adverse effect on the development of Russian democracy; to restore the atmosphere of the cold war to East-West relations, and to impel Russian foreign policy in directions decidedly not to our liking.

– George Kennan, New York Times, 1997
