Like so many empires before it, the Soviet Union eventually imploded and fragmented, falling victim not so much to a direct military defeat as to dis… - Zbigniew Brzezinski

[President George W. Bush] has a vision which can be described with two other words: Manichaean paranoia... the notion that he is leading the forces of good against the empire of evil, that in that setting, the fact that we are morally superior justifies us committing immoral acts. And that is a very dangerous posture for the country that is the number one global power. ... The fact is he squandered our credibility, our legitimacy, and even respect for our power.

This is a highly motivated, good country. It is driven by good motives. But it is also a country with an extremely simplistic understanding of world affairs, and with still a high confidence in America’s capacity to prevail, by force if necessary. (...) This is a country of good emotions, but poor knowledge and little sophistication about the world.

In the long run, global politics are bound to become increasingly uncongenial to the concentration of hegemonic power in the hands of a single state. Hence America is not only the first, as well as the only, truly global superpower, but is also likely to be the very last.
