WHAT THE HECK FOR????
It’s muslim vs muslim!
I’d give them all the guns, and when the smoke clears, THEN, eradicate Syria, for all it’s causing trouble with Israel!
Unfortunately, its not as simple as that. Syria is a much more cosmopolitan culture. The Assad regime, for all its faults (and they are many), has kept all the contending factions from ripping each other apart. Broadly speaking, the rebels are the majority population of sunni muslims, backed by the muslim brotherhood and now apparently by the US and the West. The Assad regime is backed by the rest of the population - Shia muslim, druze, christians (10% of Syria's people), Alawites (a kind of heretical muslim sect) and Russia and China.
Why are we helping the sunni and the muslim brotherhood? Who knows. Probably because we want to counter chinese and russian influence in the area. Bad way to go about it though.
