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.

We have a problem with radical Islamism and I actually think that we could work together with Russia against this enemy. They have a worse problem than America does.

I like serving America.

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.

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.

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.
