George Kennan on NATO expansion after the Soviet Union collapse

I think it is the beginning of a new cold war.  I think the Russians will react adversely and it will affect their policies.  I think it was a tragic mistake.  There was no reason for this whatsoever.  No one was threatening anybody else.  This expansion would have the Founding Fathers rolling in their graves.  We have signed up to defend a whole series of countries even though we have neither the resources nor the intention to do so in any serious way.

~ George Kennan, historian who advocated a policy of Soviet containment during the Cold War, May 2, 1998
