Just to return a bit, Japan bit off more than it could handle in China over a long run. Their settlement program in Manchuria was basically a failure economically. If they had liberated the European colonies and treated the people well in the Philippines, Indochina and Indonesia, they could have built up resources and allies. They could have turned India against the British.
The UK and the French at their heights could not retake their possessions and defend them against a Japanese occupation without the US. Australian and New Zealand could be neutralized if the Empire just asked them to stay neutral and offered economic relationships.
