I am reading the book "WWII for Dummies," which despite the name is a pretty good read. I recommend it for anyone who wants a good overview of the war. Anyway, I'm a bit confused about a certain passage I read today. It describes how "Japan had to accomodate the Soviet Union in order to keep them out of the war." It goes on to say: Although they had a non-aggression pact with the USSR, the Japanese feared that as the Soviets grew stronger, they would turn against Japan, which seemed to be growing weaker and more vulnerable to attack. Thus, the Japanese made no effort to limit the Soviets from taking units from the Chinese border and sending them to fight against the Germans." I'm assuming that "taking units" above means "moving Soviet troops." Why would Japan want to stop the Soviets from moving their troops from the Chinese border to fight the Germans, as the book implies? Thanks.
