US troops are now completely out of Afghanistan. The final days of evacuations were punctuated by violence: suicide bombers, rockets targeting the Kabul airport. And over the weekend, a US drone strike destroyed an ISIS car bomb, which the US military says was targeting the Kabul airport. It also killed 10 civilians, according to reports from family members. How will the US detect these dangers in Afghanistan, now that the US military has left? Host Marco Werman speaks with retired CIA senior intelligence officer Marc Polymeropoulos, who served in the CIA for 26 years, including in Afghanistan.
