When the Battle of Britain began, the Luftwaffe focused exclusively on the RAF, hitting airbases, shooting down aircraft, knocking out air defenses, basically trying to gain air superiority. The RAF was pushed to the breaking point, and it wasn’t until Bomber Command struck Berlin that Hitler changed priorities from striking military targets to bombing London on a daily and nightly basis. This is when the Luftwaffe lost the battle. They had almost gained air superiority and had to throw it away to strike at civilian targets.

I highly doubt the Chinese would’ve willingly rolled over and accepted Japanese occupation. The Western colonial powers had been repeatedly humiliating them for a century, the British especially, pushing drugs on them so the British could sustain their local and national economy. The two Opium Wars were fought for this reason. And then Japan and China fight for Korea, which had always been in the Chinese sphere of influence, and when Japan won, the other nations began raping their country even more. The last Emperor lost his reign, a new leader became a tyrannical despot, warlords ruled the country and did their own thing, Chiang Kai-shek and Mao Zedong had their political and military battles, and most of Eastern China was a war-torn or corrupt mess. The Japanese just stepped in and played whoever would let them have their territorial conquests. Would the Chinese accept Japanese rule? Only at gunpoint, and only because the Japanese were strong enough and terrible enough to enforce it. Most of the Japanese war crimes were committed in this country because they adopted Western ideas of racism and applied it to the Chinese. It’s a complicated situation, and those Chinese that bowed to Japan did so for power, wealth, security, or because they had no choice, and Japan brutally oppressed them anyways.

They did and it didn’t fare well for them. There’s a reason Southeast Asia was called the Southern Resource Area. Manchuria, Siberia, and parts of Mongolia were the Northern Resource Area. For seven years, sporadic conflicts and fighting broke out between the Soviets and the Japanese, and while the Soviets suffered more casualties, the Japanese were repeatedly defeated and had to sign a neutrality pact once they lost all the Soviet and Mongolian land they had taken. Nearly 60,000 people became casualties in this border conflict. It was also where Georgy Zhukov gained his first experience commanding large formations of troops in battle.
