content: Let's not. While handheld launcher (the most advanced AA weapon ISIS has) can't ever touch a F-22 something like a Russian S-400 is different. While there is almost no doubt that American air superiority would prevail eventually should a conflict in Syria involve those systems (if the Syrian Army is fought the best they have are S-300) that shit WILL cost American lives. Not a single conflict since WW2 has seen the involvement of modern anti air weapons and I'd honestly like to keep it that way.
