More than 50 State Department diplomats have called for U.S. military strikes against the regime of Syrian leader Bashar al-Assad, saying Assad has repeatedly violated Syria’s tenuous ceasefire. In an internal State Department memo, the diplomats argue for a sharp departure from President Obama’s policy on Syria, which includes targeting the self-proclaimed Islamic State but not the Assad regime. In the memo itself, however, the diplomats acknowledge the risks to increased U.S. military intervention, including the possibility of military confrontations with Russia, which is backing Assad. President Obama and his top military commanders, meanwhile, have raised concerns about the power vacuum that would emerge if Assad is removed. The memo comes as airstrikes on rebel-held sections of Aleppo forced a hospital supported by Doctors Without Borders to shut down Thursday. Aleppo residents also reported barrel bombs being dropped. Meanwhile, a federal judge has ruled against Texas, allowing the federal government to resettle Syrian refugees there.
