First bombs, now arms. The U.S. military is dropping firearms, ammunition and medical supplies to Kurdish Syrian forces near the besieged border town of Kobane. The move bolsters allies’ efforts, including scores of airstrikes, to quash ISIS. Meanwhile Turkish officials announced they would help Iraqi Kurdish troops cross into Syria to fight the ISIS threat – a huge shift for the country, which feared giving a little would lead to more unrest from Kurdish communities inside Turkey, too. Maybe the Turkish protestations over U.S. intervention were all bluster: realpolitik in action.
