In Spring of 1945, the tides of World War 2 turned. Germany surrendered to the Allies, but Japan vowed to keep fighting. To prevent further casualties, America knew they would have to demonstrate their power, and force Japan to surrender quickly. At Los Alamos, J. Robert Oppenheimer and his team raced to get ready for the first physical test of an atomic bomb. But as the scientists grew closer to seeing their creation in action, new questions arose about how, and if, such a powerful weapon should be used. Unleashing their creation might deliver a critical turning point in the war, but could also open the door to a dangerous and complicated new era for humanity.Listen to American History Tellers on the Wondery App or wherever you get your podcasts.
