Once the Eastern Bloc collapsed, what I call 'historical spontaneity' prevailed and the countries that were subject to Soviet control naturally gravitated to the West. That's where they sought their security; I don't think there was a way to avoid that. If we tried to exclude them, we would have today not one Europe, we would have three Europes: one in the West, one in the middle and one in the East, and the middle would be insecure and a tempting target. The insecurity felt [today] by Eastern Europe would be replicated on a much larger and more consequential scale.

For America, the chief geopolitical prize is Eurasia... Now a non-Eurasian power is preeminent in Eurasia - and America's global primacy is directly dependent on how long and how effectively its preponderance on the Eurasian continent is sustained.

I think if NATO haven't expanded, we would have a no-man's zone between the E.U. and NATO and Russia, and that would be very dangerous.

Without Ukraine, Russia's imperial aspirations are essentially nostalgia, but it's not a real policy.

The United States can certainly defeat North Vietnam, but the United States cannot defeat a guerrilla war which is being raged from a sanctuary through a pattern of penetration, intervention, evasion, which is very difficult for a technologically advanced country like the United States to combat.

One thing we know: Things will become even more destabilized if we don't step up Sino-U.S. cooperation. If you want to envisage a worst-case scenario, it is that Putin reveals step by step the inner weaknesses of the West, particularly in Europe, and the Chinese see in that an opportunity for emulation in the Far East, and then step by step through a gradual process we will be witnessing the emergence of Sino-Russian partnership in favor of a drastic change in the global balance of power.

Though Stalinism may have been a needless tragedy for both the Russian people and communism as an ideal, there is the intellectually tantalizing possibility that for the world at large it was, as we shall see, a blessing in disguise.
