mr. rouhani of iran visiting turkey. they are saying they can sort out syria.r interest by pulling out of syria? >> no doubt about it. could havetayed, we gotten the russians to pressure the iranians to get out. but they wanted this, just as they are doing better in yemen. 's policy of getting out of the iran nuclear deal to prevent iran from expanding its influence, this does not help at all. david: i'm really curious about jim mattis, a distinguished soldier. what is his -- what is his position in this administration? again and again to persuade the president of things. he is not always successful. --i think it was a civilian if it was a civilian in there, they might have resigned when they sent the troops to the border. but remember, he is a military person. military people are used to following orders. they make their opinion known and they follow it. that is one of the things keeping mattis in there. that's why it is not good to have a military person in charge of the pentagon. i think bob gates or any of the previous secretaries would be long gone by now
