Franklin Roosevelt dies at Warm Springs. Harry Truman, president for minutes, is told for the first time about the atomic bomb.
THE MOMENT IN CONTEXT
By 1945 Japan is beaten by every measure except the one that matters: it will not surrender. The blockade has cut imports to a trickle; B-29s from the Marianas burn the wooden cities — the Tokyo firestorm of 9–10 March kills around 100,000 people in a single night, more than either atomic bomb. Iwo Jima costs 26,000 American casualties for eight square miles; Okinawa is worse — 12,000 Americans, 100,000 Japanese soldiers, and perhaps 100,000 Okinawan civilians, with kamikazes crashing into the fleet offshore. American planners project an invasion of the Home Islands at hundreds of thousands of Allied casualties, and millions of Japanese.
From Chapter 14 — The Downfall of Imperial Japan of The War Room — WW2, 1936–1945 (AUG 1945).

- What it changed — Surrender — and a preserved throne. Japan is occupied (solely by the US), demilitarized, and given a democratic constitution that renounces war — while keeping the Emperor as symbol.…
Then ask the room: What actually ended the Pacific war — the atomic bombs, the Soviet invasion, or the blockade? Why does the answer matter? The argued answer is on the chapter page →
