The starting point for understanding the deterioration in the relationship between the U.S. and Russia lies in Washington rather than Moscow. After 1989, Russia was a defeated power.

Always beware your moment of triumphalism: such emotions are a poor steer on the future.

The world is fortunate - for the time being, at least - that it has an American president in Obama who is prepared to take a conciliatory and concessive attitude towards America's decline and that it has a Chinese leadership which has been extremely cautious about expressing an opinion, let alone flexing its muscles.

Now, I know it's a widespread assumption in the West that as countries modernize, they also westernize. This is an illusion. It's an assumption that modernity is a product simply of competition, markets and technology. It is not. It is also shaped equally by history and culture.

Nuclear arms and atomic power represent a technology in which coexistence with man is extremely difficult.
