Today a U.N. spokesperson described the situation in Aleppo as “a complete meltdown of humanity.” Pro-government forces are close to retaking the Syrian city from anti-government rebels. It represents a major victory for President Bashar al Assad. He’s been fighting an assortment of rebel groups there, and foreign fighters like ISIS and al Qaida in other parts of the country. ISIS is on the run in Syria and Iraq. Its plans for a caliphate now in disarray.
