The news from Syria keeps getting worse. As it enters its third year, the civil war between the ruthless Assad regime and groups of mostly Sunni rebels has taken nearly 100,000 lives and settled into a violent, deadly stalemate. Beyond the humanitarian costs, it threatens to engulf the entire region: Syria’s rival militias have set up camp beyond the nation’s borders, destabilizing Turkey, Lebanon, and Jordan. Refugees have made frontier areas of those countries ungovernable.
United Nations peace talks have never really gotten off the ground, and as the conflict gets worse, voices in Europe and America, from both the left and right, have begun to press urgently for some kind of intervention. So far the Obama administration has largely stayed out, trying to identify moderate rebels to back, and officially hoping for a negotiated settlement—a peace deal between Assad’s regime and its collection of enemies.
