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.

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.

Well the most likely emerging countries are Japan, Turkey, and Poland. So I would say Eastern Europe, the Middle East and a maritime war by Japan with the United States enjoying its own pleasures.

But every time new powers emerge they have to find their balance. New powers are emerging, old powers are declining. It's not that process that's dangerous, it's the emerging position that's dangerous.

War and sex are what I call the two abysmal - by that I mean deep - parts of the human condition.

Wars are times of intense technological transformation, because societies invest - sometimes with extensive borrowing - when and where matters of life and death are at stake.

With the decline of American interests in the outcome of this region, there is no glue holding it together. And the countries in this region are invented ... The last guarantor of the region's borders was the United States, and the US has basically said "the hell with it." What you're really having is the collapse of nation-states because they're not nations. They're only states.
