Book excerpt: A WWII history told from US and Japanese perspectives—“an impressively researched chronicle of the months leading up to the atomic bombing of Hiroshima” (Publishers Weekly). During the closing months of World War II, two military giants locked in a death embrace of cultural differences and diplomatic intransigence. While developing history’s deadliest weapon and weighing an invasion that would have dwarfed D-Day, the US called for the “unconditional surrender” of Japan. The Japanese Empire 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 homeland. In 140 Days to Hiroshima, historian David Dean Barrett captures war-room drama on both sides of the conflict. Here are the secret strategy sessions, fierce debates, looming assassinations, and planned invasions that resulted in Armageddon on August 6, 1945. Barrett then examines the next nine chaotic days as the Japanese government struggled to respond to the reality of nuclear war.
