Twenty-first century war adds new risks: more and more often there are no front lines, no central command, no rules of engagement - only a chaotic collision of politics, power, faith and bloodlust. Victims are as likely to be civilians as soldiers.

The object of defense is preservation; and since it is easier to hold ground than to take it, defense is easier than attack. But defense has a passive purpose: preservation; and attack a positive one: conquest.... If defense is the stronger form of war, yet has a negative object, it follows that it should be used only so long as weakness compels, and be abandoned as soon as we are strong enough to pursue a positive object.

My father wanted to be a hero. He went to the Air Force Academy, was valedictorian, and then he found himself strafing villagers in Vietnam in a war he didn't want to be in and didn't understand.
