Ukraine, a new and important space on the Eurasian chessboard, is a geopolitical pivot because its very existence as an independent country helps to transform Russia. Without Ukraine, Russia ceases to be a Eurasian empire.

The legitimacy of the leadership depends on what that country thinks of its leaders. When we lay off, more and more Iranians tend to be critical of Mahmoud Ahmadinejad. The more abusive we are and the more pressure we put on them, the more nationalism fuses with fundamentalism in Iran.

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.

The Ukrainian opposition should adopt democratic unity as its main principle, and it also must have one leader.

Hegemony is as old as mankind.

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

I think the sheer attrition of American global domination will create circumstances in which the Chinese will be tempted to reach out for more influence, including in regions in which we have special interests, such as the Middle East, from which they already obtain a great deal of their energy. And that region will be seeking some new superpower patron.
