"But even if an American infusion of arms into the Syrian arena could "ensure the collapse of the Assad regime in weeks," as some interventionists implausibly maintain, it wouldn't necessarily bring a "faster resolution to the fighting." Many Alawites are sure to fight on in the hinterlands of northwestern Syria so long as Iran is willing to supply them, while the country's Kurdish minority won't be eager to relinquish control of its remote enclaves to the likes of those now leading the rebel effort. Christian militias in Aleppo may not disband quietly. The rebels may turn on each other. Chronic ethno-sectarian and factional conflict could drag on for years."
