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.

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

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.

I think this does show that there will be some changes, not so much in Europe or Asia but certainly in the Middle East. General [James] Mattis has called for a comprehensive strategy to combat the various enemies the United States faces in the Middle East, especially Iran.

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