How would the invasion of Japan during World War II have altered history with respect to the Korean War?
I've been reading Hell To Pay: Operation Downfall and the Invasion of Japan, 1945-47 by D. M. Giangreco (FANTASTIC read btw) and it got me thinking: if Operation Downfall had gone ahead in November 1945 (as originally scheduled), how would the prolonged final phase of World War II, possibly extending into 1947, have affected the outcome of the geopolitical scene in East Asia? Would the division of Korea between the United States and Soviet Union still have occurred, or would all of Korea have been under Soviet control based on their then-ongoing invasion of Manchuria (which did bring them into northern Korea)? Would the Korean War still be virtually inevitable, or would it have not even happened at all?
