It’s spiraling out of control. As European officials plead with Ankara to keep the thousands of new refugees surging across its border, Moscow and Damascus seem uninterested in a political solution to a conflict that has claimed an estimated 300,000 lives and left many starving. As soon as Geneva peace talks began this week, Assad and his Kremlin backers attacked Aleppo and Homs. Negotiations were suspended, and U.S. officials admonished Russia for the violence. Meanwhile, cries for aid have raised billions for those fleeing the fighting, but hopes for peace are fading.
