Retired General James Mattis headed Central Command under the Obama administration. He is the new U.S. Defense Secretary. Mattis is critical but has said "there is no going back" on the Iran nuclear agreement. Mattis also has said any U.S. president regarding allies as "freeloaders" is nuts. This is different from Trump's campaign speeches, Yet the trait of Mattis in Afghanistan and Iraq duty is that of aggressively following the enemy, he has been called "Mad Dog," and the 66 year old officer brings deep battlefield experience, is highly regarded in the military ranks, and had friction with the Obama administration- traits for which he is well regarded by Trump.
