Michele Flournoy, by the way, is not just a talented and bright person. She was Hillary Clinton's secretary of defense in-waiting. So for her to give General [James] Mattis her support, that says something significant.

So in his very politically-incorrect way, I think [James Mattis] is a good counterpart to Donald Trump, who doesn't read books.

Given this president [Donald Trump] and his lack of military experience, I think it actually might be a good thing to have someone who understands the military very deeply to be counseling him.

Iran has proxies in Yemen, Syria, Iraq. You can push back against Iran without pulling out of the deal.

General [James] Mattis has said that the deal's in place. We can't unilaterally pull out of it without support from our allies because the sanctions wouldn't bite as deeply. And so he'll find other ways to push back against Iran in the various conflicts that Iran is fomenting around the [Iran] region.

I think that you will see some significant changes in the [Donald] Trump administration.

[General James Mattis] a very talented individual. He's - has a personal library of about 10,000 books and he's read most of them on military history and strategy and so forth.
