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.

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.

The poets think about war more than the social scientists.

War to me is very much like sex. You can develop a theory that says sex is primarily for the exchange of genetic material, or that it's a celebration of life, or you can make up 50,000 theories about why human beings have sex, all of which are in some sense true, all of which by themselves miss the point. Because the answer is extraordinarily complex. It may be for fun, it may be for reproduction, for financial reasons, any number of things.

Success looks like you sitting here pretty confident that an armed brigade isn't going to come pouring in here and blow your head off. Which I don't think is your major concern. Therefore, the United States' foreign policy is successful.

If you lose yourself to rage in the complexity of battle, you are going to be lost.

The most horrible sort of war is civil war.
