Like, really? Get real.
Syria is a Sunni Muslim majority state, ruled by a small Alawite elite led by Assad, the people are going to rebel again sooner or later, even if the war ends now, that's just reality.
The Sunni 'majority' you speak of counts Kurds, Sufis and others not predisposed to a bloody revolution. Add the 10% Christian population and your argument is made of straw.
A minority of Sunni extremists, of which many are foreigners, are driving this civil war in order to impose their will on a composite majority of Sunnis, Shiites and Christians. If it weren't for them and the nations driving them, Syria would have accepted the Geneva plan long ago.
'Get real', bwahaahaa. You're a babe in the woods.
