The history of the Soviet-Japanese conflict in WW2 goes beyond this incident in 1945. Before the war officially began, the Soviets (under the great Gen. Vassily Zhukov) destroyed the vaunted Kwantung Army that was based in Manchuria/Inner Mongolia.
What year was that, when Zhukov destroyed the Japanese army in Manchuria? I do not recall that bit of history. I do recall the Japanese handing the Russians a defeat in 1905.
Military history is a subject that my son and I, are both into fairly well.
Which made the Japanese think twice about getting involved in a war against the Soviets.
