Why do three-quarters of NATO [countries] get away with not paying anything? They have to pay their bills.

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.

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.

I like serving America.

I grew up as a kid with very little. I could enjoy a peanut butter and jelly sandwich or peanut butter crackers.

What I know is it is a disservice to those who continue to serve to think that there's going to be a civil-military breakdown because those who serve, they know who they serve. They know what their loyalties are, that's why you take an oath to the Constitution and your loyalty lies in the chain of command and your buddies. That's always been there. We are a professional military.

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.
