I can't disagree with that. To the Soviets, the war was something that was fought on a daily basis. To the western allies, many days or weeks had no significant ground combat The Soviet spy Richard Sorge (NOTE) found out the Japanese only planned a limited incursion into the Soviet Union. When Stalin was sure Sorge's information was valid, many Soviet Army divisions were transferred from being prepared to fight the Japanese on the eastern front to the western front against Germany.Yes, I agree that Midway was one of the most decisive battles in WWII, but I still stand firmly on my position that Moscow was the most decisive.
NOTE;
Richard Sorge was the Soviet spy in Tokyo who found out in October of 1941, that the Japanese planned to attack "Pearl Harbor" (by name) in the first week of December! The information was passed to Moscow which forwarded it to Washington!
Yes, after the Battle for Moscow all major battle were won by the Soviet Union.It was the turning point of the war, when Soviet forces finally stopped the once invincible German war machine
I have never come across any information on what the Soviet military planned to do concerning the invasion of Japan beyond the Kuril Islands.
