Anyway, given how the trouble in Syria is fundamentaly sectarian Sunni-against-Shi'ia based, being fueled by poverty and boredom, like when Protestants and Catholics were attacking each other in northern Ireland, an idea keeps popping into my head...
... Yes, in an ideal world Uncle Sam would not be meddling in the middle-east, but his Wall Streeters are too chicken-sh*t low-vision non nation-minded to think about investing in energy self-sufficiency, and you'd think he'd at least just buy the oil and go like he does with those tin-pot tyrants in Nigeria, but Israel plopped themselves right in the middle of it, and they control all his banks.
So... if you're going to be meddling, why not go all the way?
Arabs are already accustomed to moving around and re-settling as refugees, so why not just divide the middle-east into three parts: east of the Tigris-Euphrates for Shi'ites, west of the Tigris-Euphrates for Sunnis, and the land between those two rivers for the normal objective rational Arabs who don't give a rat's a*s about denomination... the ones who just want to do business and live a comfortable life, thus turning the land between the two rivers into Arabia's greatest free-enterprise zone?
It's not like mass migration/relocation based on theology hasn't happened before. Who can forget how Pakistan and India split?
Speaking of which... hmm... how come Hindu and Muslims were okay living around each other on that subcontinent before the Brits showed up, but after British influence, tens of millions of Muslims and Hindu had to start hating each other and migrating in order to form separate nations?
