We may stay, add more men there. We need to be wary, this is not a country we ever declared war on. I'm all against Assad, that situation is very precarious, his age old enemies are the Muslim Brotherhood, they warred with them circa 1983. At least, half of those fighting against Assad have been Jihadist types, I"m sure a number of rebels are good people as well. This current conflict grew out of protests.
Trump is approaching this intelligently, not like a hothead and I commend him for it.
