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."

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

I saw the relation with Russia as necessary to the U.S., for the interests of the U.S. We worked very closely with them on the Sochi Olympics. We were working closely with them on the Iranian nuclear deal.

The United States should not have to intervene in every single problem around the world. The voters of this country are reacting in a very big, broad way to Mr. Trump. They are frustrated by lousy decisions made by both George W. Bush and Barack Obama. Look at the mess we have.

When you look back, history is not going to be kind to these last 16 years from 2000 to 2016.

Trump realized that you had to drive a stake through the heart of this establishment and that millions of Americans do not feel represented by this sort of clique in Washington.

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.
