140 Days to Hiroshima: The Story of Japan's Last Chance to Avert Armageddon

Join us for an engaging discussion on the lead up to the dropping of the Atomic Bomb on Hiroshima, 76 years after that historic day, between author David Dean Barrett and the Museum’s Senior Historian Rob Citino, PhD.

During the closing months of World War II, as America’s strategic bombing campaign incinerated Japan’s cities, two military giants locked in a death embrace of cultural differences and diplomatic intransigence. The leaders of the United States called for the “unconditional surrender” of the Japanese Empire while developing history’s deadliest weapon and considering an invasion, "Downfall," that would have dwarfed D-Day. Their enemy responded with a last-ditch plan termed "Ketsu-Go," which called for the suicidal resistance of every able-bodied man and woman in “The Decisive Battle” for the Japanese homeland. But had Emperor Hirohito’s generals miscalculated how far the Americans had come in developing the atomic bomb? How close did President Harry Truman come to ordering the invasion of Japan?

Within the Japanese Supreme Council at the Direction of War (also known as “the Big Six”), Foreign Minister Shigenori Tōgō risked assassination to save his country from annihilation. But the Big Six remained defiant, refusing to surrender even after the atomic bombings of Hiroshima and Nagasaki. How did Japanese leaders come to this impasse? The answers lie in this nearly day-by-day account of the struggle to end the most destructive conflict in history.
