Were the atomic explosions on Hiroshima and Nagasaki in August 1945 the only reason for the Japanese capitulation? This is what official history has retained. The real cause of the surrender of the Empire of the Rising Sun is however to be found on the side of the USSR. Stalin, wanting to recover the Kuril Islands and Sakhalin, confiscated by Tokyo in 1905, is ready to support the American landing. But President Truman's choice to use the bomb takes him by surprise. On August 9, breaking the Russian-Japanese non-aggression pact, the Red Army entered Manchuria and annihilated the Japanese troops. For fear of the red invasion, Japan capitulates.
