We have zero strategic thinking out of our White House. And we have a national security structure that has lost its way when it comes to strategic thinking and strategic decision-making.

Foreign policy is about US national security, it is definitely not non-intervention. It is definitely not isolationist. That's where people want to hear what they want to hear and not listen to what Donald Trump says. It is about national security for the United States, and that's fine.

I think all of Europe has been too soft on the refugee crisis.

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."

Why do we go through all the nonsense with security at our airport? It's not because the Catholic Church is falling apart.

Donald Trump is a great listener, and he's a good challenger. He doesn't come across as a person who thinks he knows it all. In fact, he once told me he has had lot of things to learn.

One thing I agree with Donald Trump on is, there's something going on in the Muslim world.
