Obama's idea of "no boots on the ground" does seem to mean arming, training, and financing armies of mercenaries. They're mostly not going to die if they don't have to for someone else's agenda. They'll take the money and arms and leave. They won't give up power and weapons easily (if ISIS hasn't already confiscated them) when the fighting's over and the US decides who the next leader will be.
Except for the globalist agenda, there's no sane reason to not be supporting Assad.
