During a long and distinguished career with the U.S. State Department, Ambassador Christopher Hill was sent to some of the most dangerous outposts of American diplomacy, from the Balkans to North Korea to Iraq. In his memoir, “Outpost: Life on the Frontlines of American Diplomacy,” he takes us from one-on-one meetings with Slobodan Milosevic, to Bosnia and Kosovo, to the Dayton conference, where a truce was brokered. He draws upon lessons learned as a Peace Corps volunteer in Cameroon early on in his career and details his extensive experience as a U.S. ambassador.
