There is a radical and unprecedented shift [in war] that is part of the general transformation of civilization. First, understand that the past 150 years of warfare are totally unprecedented in that we introduced a breathtakingly inefficient technology: guns. In the First World War, and this is not an exaggeration, it took 10,000 rounds of ammunition to kill one person. Any given shot had a one in 10,000 probability of ending someone's life.

Politicians are enormously smart and rational. They don't have the same interests as businessmen ... But a man rises to the top of the United States. He's clawed his way out of 330 million people. OK. He didn't do that because he was dumb, or lucky, or something like that. He understands power. And he understands how to take it. And he understands how to keep it.

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.

The importance of the question and the availability of an answer are two different things. I'm not willing to state that because the question is fundamental, therefore I possess the answer. And I'm certainly not willing to say that since I don't possess the answer, I'll pretend that I do.

I think there are worse things than war. For example, injustice.

There has never been a century that has not had a systemic war - a systemic war, meaning when the entire system convulses. From the Seven Years' War in Europe to the Napoleonic Wars of the 19th century to the World Wars, every century has one.

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