I disagree.
Without the distraction of the US Navy and the US Military, the Japanese would have easily taken over sparsely populated Australia and India would have been the next logical step from Burma.
A certain Mr. Bose and the Indian National Army were not too displeased with the Japanese. (In fact, an international airport has been named after him).
No Indian wanted to replace the yoke of the British which was light with the demonic yoke of the Japanese
Without the US Navy and US Military, the Indian army kept the Japanese at bay pretty well, thank you
Over time the Indian army would have smashed through into Burma, while the insurgent movement in Indonesia, the Philippines and Malaysia would have cut off the legs under the Japanese.
