The battle over Aleppo brings new pleas for intervention

Rebel forces in Syria won a rare victory this month by getting some food to 300,000 starving citizens trapped by constant bombing in the city of Aleppo. The US reportedly looked the other way while moderates teamed up with a former affiliate of al Qaeda. Nevertheless, a crisis of massive proportions is still growing.

America's Holocaust Museum, is among those demanding action. President Obama's legacy has already been called into question. But, despite speculation that Russia's involvement is timed to the US election, the Trump and Clinton campaigns have had very little to say.
