That wasn't where I was going, but since you asked...no.
My point was mainly geared towards US/ Allied citizens fighting for an "allied" cause is the same as some non-allied nation (Chechnya or China or whoever) going to fight for ISIS or even Assad. They don't belong there and we're hypocrites if we complain about a Krygyz or Uzbek or whoever fighting for a non-US/ allied cause. I think if your nation is currently involved in fighting ISIS and you've joined that side then you're a traitor.
I don't think I'm articulating my thoughts very well.
