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.

[General James Mattis] said, reading allows you to learn from other people's mistakes without filling body bags with the bodies of your soldiers as you learn on the battlefield.

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

t I think what [James Mattis] will do with the deal is monitor it very, very carefully and make sure that Iran is complying with every stipulation of it.

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.

General [James] Mattis has got a really intellectual mindset about how the United States should go about protecting its national security.
