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.

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] is a Marine's Marine who has served in combat in both Afghanistan and Iraq.

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.

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

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

[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.
