NATO as a political alliance does need to be relooked at in terms of everything - resourcing, capabilities.

Russia ought to get Iran to back out of the proxy wars they are involved in.

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

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.

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.

I think we have such a political cesspool in America right now.

NATO was formed post-World War II. We're a little bit more than a half-century old. Do we want NATO to go on for another half-century? I think that the answer is, sitting here today: I don't know. If I had to bet on it, I would say, yeah, we have to have these alliances going forward and see who's going to pay for them.
