Because the US has control of the sea. Because the US has built up its wealth. Because the US is the only country in the world really not to have a war fought on its territory since the time of the Civil War ... Therefore we can afford mistakes that would kill other countries. And therefore we can take risks that they can't ... the core answer to why the United States is like this is we didn't fight World War I and World War II and the Cold War here.

Recent presidents have gone off on ad hoc adventures. They have set unattainable goal because they have framed the issue incorrectly, as they believed their own rhetoric.

The Chinese central government will slowly and steadily lose authority while regional armies [gain power]. The Western powers are going to take sides to protect their investments - they have put billions of dollars into Shanghai. Their fear is that [these investments] are going to be expropriated by a warlord from the interior who will sweep down on Shanghai. They will try to form alliances with warlords to protect their concessions, and there will be a huge flow of weapons into China.

I think the personal and psychological aspects of war remain the same. War is about killing and dying. A man or woman stands at the post and there is a very real possibility of dying in the next five minutes. Whether he dies or not depends partly on him and partly on luck, and yet he must continue to function.

The United State has a net worth against which our debt is a joke ... we wrote in 2008 the United States is going to come out of this recession fast. The Europeans are going to fragment. The Chinese are going to be cremated. Why could we come out of it? Why has all economic theory been proven wrong? Because we're rich and we could afford it.

It has always struck me as the world's great fortune that the two great superpowers were the United States and the Soviet Union, who managed the Cold War with meticulous care in retrospect. Imagine the European diplomats of 1914 or 1938 armed with nuclear weapons. It is easy to believe they would not have been as cautious.
