My guest today, Dr. Sharifullah Dorani is the author of the new book America in Afghanistan: Foreign Policy and Decision Making from Bush to Obama to Trump’ as the title suggests, the book examines the history of US involvement in Afghanistan from 2001 through the first two years of the Trump presidency. And in this conversation we discuss what both what has stayed the same and what has distinguished the Trump administrations approach to Afghanistan from his predecessors.   We recorded this conversation just a few weeks after Trump, via Tweet, suggested a precipitous withdrawal of US troops from Afghanistan, which is of course America's longest war. So we do discuss what role American troops are currently playing in Afghanistan and what some of the debates about troop levels have been. We also discuss the ongoing diplomatic efforts led by Trump's envoy to Afghanistan, former US Ambassador to the UN Zalmay Khalilzad.
