We'll be seeing more reports like this as the U.S. and NATO rotate out of Afghanistan. Even at ten years in, there's much work to be done. The terrorists at the clip are likely Tehreek-e-Taliban Pakistan (TTP), a militant organization allied to Mullah Omar, who was the Supreme Leader in Afghanistan prior to the initial rout of the Taliban during Operation Enduring Freedom. Mullah Omar in turn was closely linked to Osama bin Laden and al Qaeda. This is why we fight.
