A horror.

The first Iraq war? Saddam Hussein invaded Kuwait. He might have invaded the next country, and the next.

I bet Israel would have done something about it, and I bet Saudi Arabia maybe would have talked to Israel. I think if it would have been left to the region, they might have taken care of Saddam Hussein in 1990 and we wouldn't have the problems we have today.

What if there's genocide and terrible suffering in a country?

It's a tragedy, and we can have a moral statement, but you can't use force of arms to invade other countries to make them better people. Our job is to make us a better people.

You'd pull American troops out of Korea, Germany, the Middle East, everywhere?

I would. Under the Constitution, we don't have the authority to just put troops in foreign countries willy-nilly when we're not at war.

If North Korea invades South Korea, we should just leave it alone?

Sure, but it's not going to happen. South Korea's about 10 times more powerful than North Korea.

If China invaded Taiwan?

That's a border war, and they should deal with it.

If Canada invades Montana?

I think that might be a little bit different. Montana probably could take care of it, but we'd probably help them out from Washington if that happened.

That's a role for the federal government?

Oh, sure.

Next week: Ron Paul on subsidies to special interests.
