Toppling secular dictators in the Middle East has only led to chaos and the rise of radical Islam.

We have to have a more realistic foreign policy and not a utopian one where we say, oh, we're going to spread freedom and democracy, and everybody in the Middle East is going to love us. They are not going to love us.

I’ve never argued against any technology being used when you have an imminent threat, an active crime going on. If someone comes out of a liquor store with a weapon and fifty dollars in cash, I don’t care if a drone kills him or a policeman kills him.

You have to decide in advance whether you're ready go to war. If you guys are ready to send a million troops into Ukraine and fight World War III, you're going to do it without my support because I think that's a really foolish notion.

I think we can all agree [Bashar] Assad is a bad and evil actor, but I'm not so sure that we want the Islamic rebels to be in charge of Syria either.

I think that, most importantly, when I see issues of war, I see them in a personal vein, and I am reluctant to go to war unless there's a real, valid American interest because I've seen the wounded soldiers.

I think it's fair to point out that there is bias in the media on both sides, both right and left. And that it's very hard to find objective news because we have gotten, particularly as you watch cable news, it's so dominated by opinion.
