In 1944, Franklin Roosevelt selected as his next running mate a hardworking, uncontroversial senator from Missouri named Harry Truman. On April 12, 1945, Roosevelt died, and Truman, after only 82 days as vice president, was thrust into the presidency, a turning point that generations of historians have inexplicably addressed as shocking. Yet Roosevelt's failing health had been plain to staffers for at least a year. With the end of his life looming, FDR met alone only twice with his vice president, and failed to brief him on domestic issues or foreign affairs, most notably his intentions for ending World War II, including the existence of the atomic bomb program. It was, as author David L. Roll contends, one of the most irresponsible oversights in presidential history. As president, Truman was woefully unprepared. He immediately faced the surrender of Germany, a continent in ruins, and the decision to use the atomic bomb against Japan. Most significantly, the Soviet Union, an ally during the war, was growing increasingly hostile towards US power. Truman inherited FDR's hope that peace could be maintained through cooperation with the Soviets, but he would soon learn that imitating his predecessor would lead only to missteps and controversy. Spanning the years of transition, 1944 to 1948, Ascent to Power explores Roosevelt's post-war illusions, and the very real challenges faced by Truman as a supposed "accidental president," including the revival of Western Europe, the reform of Japan, and the hotly-debated birth of Israel. Detailing the long shadow cast by FDR, this remarkable book reveals Truman's struggle to emerge as a president in his own right, and how the decisions made during these years of transition changed the world. From Franklin Roosevelt's final days through Harry Truman's extraordinary transformation, this is the enthralling story behind the most consequential presidential transition in US history. When Roosevelt, in failing health, decided to run for a fourth term, he gave in to the big city Democratic bosses and reluctantly picked Senator Truman as his vice president, a man he barely knew. Upon FDR's death in April 1945, Truman, after only 82 days as VP, was thrust into the presidency. Utterly unprepared, he faced the collapse of Germany, a Europe in ruins, the organization of the UN, a summit with Stalin and Churchill, and the question of whether atomic bombs would be ready for use against Japan. Meanwhile, the Soviet Union was growing increasingly hostile towards US power. Truman inherited FDR's hope that peace could be maintained through cooperation with the Soviets, but he would soon learn that imitating his predecessor would lead only to missteps and controversy. Spanning the years of transition, 1944 to 1948, Ascent to Power illuminates Truman's struggles to emerge as president in his own right. Yet, from a relatively unknown Missouri senator to the most powerful man on Earth, Truman's legacy transcends. With his come-from-behind campaign in the fall of 1948, his courageous civil rights advocacy, and his role in liberating millions from militarist governments and brutal occupations, Truman's decisions during these pivotal years changed the course of the world in ways so significant we live with them today.
