The kind of problem that America faces in Iraq is a little bit the kind of problem that Israel faced in dealing with Hezbollah. If the conflict, the theater of conflict enlarges, it's going to become more and more absorbing and more and more costly.

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.

We cannot leap into world government through one quick step... The precondition for eventual and genuine globalization is progressive regionalization because by that we move toward larger, more stable, more cooperative units.

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.

However, if Moscow regains control over Ukraine, with its 52 million people and major resources as well as access to the Black Sea, Russia automatically again regains the wherewithal to become a powerful imperial state, spanning Europe and Asia.

In the longer run, I happen to think that Russia really has no choice but to become gradually more associated with the Euro-Atlantic community. Because if it isn't, then it's going to find itself essentially facing China all by itself, facing the Euro-Atlantic community all by itself.

I think the US has the right to have its own national security policy. I think most Americans would agree with that. And therefore clarity on this issue is important and especially if we commit ourselves, explicitly and bindingly, to Israel's security.
