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.

Obama's decision to leave, to not sustain the victory that resulted after eight years of fighting, from 2003 to 2011 in Iraq, was another incredibly stupid decision. It was totally based on politics, not based on any notion of national security. It's a nightmare for our national security. And then you have the Libya intervention.

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

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.

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?

There's one thing that I know about myself, I could wash dishes and be happy.

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