Top Pentagon brass blamed the lightning-quick Taliban takeover of Afghanistan and botched U.S. withdrawal on bad intelligence during sometimes intense grilling on Capitol Hill Tuesday.

The questioning, a month after the U.S. military’s departure from Kabul, focused on the catastrophic failure of the U.S.-trained Afghan army, a humiliating withdrawal that left hundreds of Americans behind, a suicide bombing that killed 13 U.S. service members, and a drone strike that killed an aid worker and seven children.
