Hamid Karzai served as President of Afghanistan from 2001 until 2014. Karzai's presidency spanned the lion's share of the 20 year-long US-led intervention in Afghanistan. Though Karzai often frustrated American leadership, my guest today claims that the Americans made many mistakes in their dealings with Karzai. That guest would know, too; he is Ronald Neumann, who served as US Ambassador to Afghanistan from 2005 until 2007 under President George W. Bush.  He is a friend of Karzai's, and he is the now president of the American Academy of Diplomacy in Washington, D.C. (@acadofdiplomacy on Twitter).
