The Back Channel draws on William Burns's thirty-three years as a career diplomat to offer both memoir and argument for diplomacy's essential role in American foreign policy. Burns, who would later become CIA Director, served under five presidents from both parties, witnessing the collapse of the Soviet Union, the invasion of Iraq, the Iran nuclear negotiations, and the deterioration of U.S.-Russia relations. His account provides unprecedented access to diplomatic encounters, including face-to-face meetings with Vladimir Putin, where Burns warned of Russia's resistance to NATO expansion and growing authoritarianism. The book traces Burns's career from young Foreign Service Officer in Jordan through ambassadorships to Jordan and Russia, and eventually to Deputy Secretary of State. Throughout, he demonstrates how patient relationship-building and precise communication can achieve results that military force cannot. Burns is candid about diplomatic failures alongside successes, examining the mistakes that led to the Iraq War and missed opportunities with Russia. For readers concerned about America's role in an increasingly complex world, this book makes a compelling case for investing in professional diplomacy. Burns writes with the clarity and measured judgment that characterized his distinguished career.
