Over the course of more than three decades as an American diplomat, William J. Burns played a central role in the most consequential diplomatic episodes of his time-from the bloodless end of the Cold War to the collapse of relations with Putin's Russia, from post-9/11 tumult in the Middle East to the secret nuclear talks with Iran.Burns draws on a treasure trove of newly declassified cables and memos to offer rare insight into US diplomacy in action. He illuminates the back channels of his profession, and its value in a world that resembles neither the zero-sum Cold War of his early career, nor the 'unipolar moment' of American primacy that followed.The Back Channel recounts with vivid detail and incisive analysis the seminal moments of a legendary career and makes an eloquent and impassioned argument for diplomacy in an increasingly volatile world.
