The whole point of being in the Army is wanting to get killed, wanting to test yourself to the limits. Now you have to fly 15,000ft above the war zone to avoid getting hit. I don't think there is any point in having wars if that's how you're going to behave. It's pathetic. All this whining!

One of the things that ultimately led me to leave mathematics and go into political science was thinking I could prevent nuclear war.

You cannot be politically correct in a war.

I think war is based in greed and there are huge karmic retributions that will follow. I think war is never the answer to solving any problems. The best way to solve problems is to not have enemies.

We're fighting an enemy that is far different than any we have got before. It's a nontraditional kind of war, and I think we need to step back, recalibrate how we go about protecting our borders and protecting our people, and resetting our position in the world.
