Well, I see the Soviet invasion as outside the scope of the topic at hand, the United States apologizing for dropping the Atomic bombs on Hiroshima and Nagasaki. So, I have left that sleeping dog lie. The Soviet Union went through Japanese forces "like a hot knife through butter", because The Kwangtung Army had been thoroughly mined for their experienced personnel and first rate units to send to the Pacific to fight the US forces or to be sent to the Home Islands for the last stand there. The remnants were under-equipped or poorly equipped second and third rate units - basically human cannon fodder. They were also widely scattered along the Soviet border, and tended to be clustered around large redoubt forts. So, their collapse was more of a foregone conclusion, rather than a major feat of arms on the Soviets part. Oh, the Japanese government, and specifically, the Emperor knew. All because of Yoshio Nishina, who lead Japan's atomic bomb project. Nishina, made known his evidence and conclusions to his friend, Inosuke Furuno, President of the Domei News Agency. Furuno, then took Nishina's evidence and went to see Count Nobuaki Makino, who was close to Emperor Hirohito, on August 7th. On August 8th Makino visited with Emperor Hirohito and presented Nishino's evidence and appealed for an end to the war. Nishino who was to have visited Hiroshima on August 7th, was unable to reach the city until August 8th, at which time he began his investigation into the atomic blast, and sent his reprt of to Tokyo. On August 10th, he traveled to Nagasaki and also conducted investigations there. However, he and his scientific team were unable to provide medical help to the medical victims, because the direct radiation effects of the atomic blast were quite severe, and there was little that could be done for many of the most severely wounded. I could not agree more. Despite what Japanese Army Intelligence had been telling the Japanese leadership(political & military) for months, about a large Soviet build up, the Japanese deluded themselves that the Soviet Union would not attack...Even though the Soviet Union had already provided notice that they were withdrawing early from the Neutrality Pact.
