Never before has a populist democracy attained international supremacy. But the pursuit of power is not a goal that commands popular passion, except in conditions of a sudden threat or challenge to the public's sense of domestic well-being. The economic self-denial (that is, defense spending) and the human sacrifice (casualties, even among professional soldiers) required in the effort are uncongenial to democratic instincts. Democracy is inimical to imperial mobilization.

America is the only superpower. But our leadership is being tested in the Middle East, and some of the things that we have done in the Middle East are contributing to a potential explosion region-wide. And if that explosion gets out of hand, we may end up being bogged down for many years to come in a conflict that will be profoundly damaging to our capacity to exercise our power, to address the problems implicit in this global awakening, and we may face a world in which much of the world turns away from us, seeks its own equilibrium, but probably slides into a growing chaos.

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.

The Israelis are becoming increasingly like the white supremacist South Africans, viewing the Palestinians as a lower form of life, not hesitating to kill a great many of them and justifying this on the grounds that they are being the objects of terrorism, which is true.

Bipartisanship helps to avoid extremes and imbalances. It causes compromises and accommodations. So let's cooperate.

Shortly, the public will be unable to reason or think for themselves. They'll only be able to parrot the information they've been given on the previous night's news.
