Clarissa Ward, CNN's chief international correspondent, spent 3 weeks in Afghanistan, first with the Afghan military in Kandahar, just before it fell; then in Ghazni province, in territory that was taken over by the Taliban, and in Kabul, where the Taliban were celebrating their victory. After reporting on the chaos and danger at the airport, as thousands of people tried to escape on U.S. military flights, she got on an Air Force C-17 to Doha, Qatar, along with hundreds of evacuees. We'll talk about what she learned and what she experienced.
