We’re nearing the 20th anniversary of the 9/11 terrorist attacks and the start of the war in Afghanistan. Following the withdrawal of US troops from Afghanistan, the Taliban have seized control of the country, and the US-backed government has collapsed. Meanwhile, Turkey, Russia, China, and other powers remaining in the region are openly jostling for influence in the vacuum left by US forces. Katherine Zimmerman, a Fellow at the American Enterprise Institute, has followed US counterterrorism issues and the war in Afghanistan closely. On this episode of Overwatch, she discusses the state of US counterterrorism efforts and American involvement in Afghanistan.
