Why are all these refugees rushing to the beauty and strength of Europe and to the United States and not rushing to their own capitals or the capitals of the Muslim world? We ought to be pushing back. We ought to be putting people back on these boats and putting them back into the places where they came from and telling these leaders in the Arab world, "You have a responsibility as well."

This [U.S.] bombing in Libya. So what are we doing in Libya? We just dropped some bombs on someone who we found is a leader there, maybe we killed some group attending a leadership meeting. Does this mean the problem is going to go away? No. It means we're going to have worse guys.
