How the World Coud Intervene in Syria

"...The second scenario is even worse. A full-fledged civil war in Syria could quickly become a proxy war between Turkey, Saudi Arabia, Qatar, and/or at least some NATO countries on one side against Iran, Russia, Hizbollah, and possibly Iraq and Hamas on the other. (what kind of lineupnis this? Qatar vs. Russia?...) That is a deeply dangerous and destabilizing prospect. Streams of refugees will burden and potentially disrupt local politics in Jordan, Turkey, Iraq, and Lebanon. The Kurds in Iraq and Turkey and the Druze in Lebanon might join in on the side of their respective Syrian cousins. The economy of the entire region would be badly disrupted, even independent of any impact on oil prices. And Syria itself would be devastated, inviting the same power struggles and sectarian violence we see in Iraq today.
