Why US Dropped Bomb on ISIS

The dropping of a "mother of all bombs" Thursday by the United States on an ISIS cave and bunker complex in Achin district in eastern Afghanistan should be understood as part of an effort to reverse a war that is not going well for the Afghan government and, by extension, the United States.

Thirty feet in length, weighing 21,000 lbs and creating a mushroom cloud seen up to 20 miles away, the "mother of all bombs" was unleashed by the United States in Afghanistan.
