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.

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.

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 threat of nuclear warfare is very, very low. Trump is no fool, and he sees the world as a globalized world.

What do you do when you get out of the military, you stop serving? There are 26 presidents who served in the military. More than half of our presidents... that means that you stop being an American?

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.

I'm standing up for the U.S. But it's hard when Russians don't have any respect for the current leadership.
