As commander-in-chief, I will do whatever it takes to defend America. But in defending America, we cannot lose what America stands for.

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.

We have to decide whether our fear is going to get the better of us. Once upon a time we had a standard in our country that was 'innocent until proven guilty.' We've given up on so much. Now, people are talking about a standard that is 'if you have nothing to hide, you have nothing to fear.' Think about it. Is that the standard we're willing to live under?

There is often variations of evil on both sides of the war. What we have to decide is whether or not regime change is a good idea. It's what the neoconservatives have wanted. It's what the vast majority of those on the stage want.

Who gets to decide who's an enemy combatant and who's an American citizen? Are we really so frightened and so easily frightened that we would give up a thousand-year history?

I do not yet know if I will find a Romney presidency more acceptable on foreign policy. But I do know that I must oppose the most recent statements made by Mitt Romney in which he says he, as president, could take us to war unilaterally with Iran, without any approval from Congress.

I've put pencil to paper... and I've said I would cut spending, and I've said exactly where. Each one of my budgets has taken a meat axe to foreign aid, because I think we ought to quit sending it to countries that hate us.
