In 2014, a number of President Obama’s US ambassador appointees were confirmed by the Senate, despite their lack of diplomacy experience. Appointees such as Noah Bryson Mamet , the new ambassador of Argentina, have never visited the country where they will be stationed. While a president naming political appointees as ambassadors is not new, international policy experts such as Penn State International Affairs professor and retired U.S. Ambassador Dennis Jett are concerned. In his new book “ American Ambassadors: The Past, Present, and Future of America’s Diplomats ,” he looks at the various paths to becoming a diplomat. Jett joins Dan Simpson, another former ambassador and a Pittsburgh Post-Gazette columnist, to discuss the role of ambassadors in this ever more globalized world.
