One of the things I learned was that Putin has no respect for the United States leadership. Not for the United States, but the leadership.

We have a centrist nationalist group of people in this country, lots of them, and we have a socialist group of people in this country, lots of them. And that's not, to me, the American idea.

NATO as a political alliance does need to be relooked at in terms of everything - resourcing, capabilities.

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."

Donald Trump has no intention to step away without examining all relationships that we have. His intent is to relook at the way we are organized globally, where the US is sort of expected to be a global leader, but relook at these alliances and these charters that we are under to make sure that they are still viable for the 21st century. It doesn't mean that President Trump comes into office and NATO goes away.

NATO was formed post-World War II. We're a little bit more than a half-century old. Do we want NATO to go on for another half-century? I think that the answer is, sitting here today: I don't know. If I had to bet on it, I would say, yeah, we have to have these alliances going forward and see who's going to pay for them.

I would have preferred to capture bin Laden and expose how he uses Islamic ideology for his own purposes.
