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

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

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.

Why do soldiers fight? They join because they believe in a higher cause -- protecting religion, their nation, defending against a foreign nation. But why do soldier stay and fight? Soldiers aren't individuals. They are part of a unit. And that unit is led by a commander. If they don't trust their commander ... if there is no leadership, there is nothing.
