Currently, the United States has troops in dozens of countries and is actively fighting in Iraq, Syria, Libya, and Yemen (with the occasional drone strike in Pakistan). In addition, the United States is pledged to defend 28 countries in NATO. It is unwise to expand the monetary and military obligations of the United States given the burden of our $20 trillion debt.

You can see why there are more people wanting to come from economically-distressed areas, and they can't all come to America. So it gets into the valid, legitimate debate over immigration as to how do we choose. Do we have a diversity lottery and take people from everywhere, do we base it more on merit?

I just can't vote to go to war unless I think there's a real clear-cut American purpose in the war, that we're going to win and that we're not going fight for stalemate.

You wonder why your government's completely broken? We lurch from deadline to deadline, and it's on purpose really. We do deadline to deadline because ... 'we've got to go. It's spring break, we're going to be late for spring break, and we've got to go, so we've got to finish this up before we go.'

I think those who have wanted regime [of Bashar Assad] change have made a mistake.
