The Cold War dominated history for nearly half a century, locking two superpowers in a global rivalry that ended only with the collapse of the Soviet Union. For millennia, the outcomes of war had been determined on the battlefield, but the most decisive moments of the Cold War occurred in the carefully worded exchanges of world leaders meeting face to face. In the shadow of the bomb, the summit meeting offered an opportunity for heads of state to rattle sabers and cross swords without triggering nuclear apocalypse. Drawing on extensive archival material, prizewinning historian David Reynolds describes the outsized personalities who negotiated the course of twentieth-century history.
