To the amazement of many, Syria’s “cessation of hostilities” generally held for two months. To the surprise of none, it crumbled this week with devastating consequences. More than 200 people have been killed this week in Aleppo between rebel attacks on government-controlled neighborhoods and government air-strikes on rebel-held territory. Most alarming was Wednesday night’s air raid on Aleppo’s Quds hospital, killing more than 20 people, including six staff members. Targeting hospitals wreaks havoc beyond the rubble. There are now two fewer doctors, two fewer nurses to care for Aleppo’s traumatized survivors. The message is clear: no place is safe. Secretary of State John Kerry condemned the attack and blamed the Syrian government for it. With several dozen more American troops deployed to Syria in the battle against Islamic State, can Kerry and other diplomats who brokered the last cessation of hostilities duplicate their magic?
