The signing ceremony of the Act of Capitulation took place on September 2 aboard the United States Navy battleship USS Missouri (BB-63). After several days of backroom negotiations and failed attempts to destroy the stockpiles of biological and chemical weapons of Unit 731 in Manchuria, which were captured by Soviet paratroopers, and the collapse of the Kwantung Army, in August 15, Hirohito addressed the nation by radio and announced the surrender of Japan. The total shock of these events forced Emperor Hirohito to intervene and compel the big six to agree on the terms of ending the war, taken by the Allies in the Potsdam Conference. Only hours later, the Americans dropped a second nuclear bomb on Nagasaki, destroying a small portion of it. Late in the evening of August 8, according to the Yalta agreements, the Soviet Union declared war on Japan, and shortly after midnight on August 9, attacked Manchukuo and Mengkukuo. On August 6, 1945, the United States dropped a nuclear bomb on Hiroshima, flattening the center of the city. After invading China, Japan struck southwards, invading and conquering British Malaya and the Dutch East Indies ( Indonesia ), in hopes of securing their resources, followed by an invasion of the 24px British Raj. In 1937, after the Marco Polo Bridge Incident, Japan declared war on China, beginning the Second Sino-Japanese War in which Japan invaded and conquered much of eastern China, installing additional puppet regimes along the way, including Mengkukuo and the ' Reorganized National Government of the Republic of China '. Some consider that World War II actually began with the invasion of China by Japan, first by taking Manchuria and installing their puppet the Manchukuo regime.
