I am wondering if this is possible. My guess is that better intelligence analysis is carried out and noted. Competent defence in the Philippines and Malaya. Plus a prepared Pearl Harbor so that the attackers lose heavily.
In OTL Roosevelt was not sympathetic to European colonialism. So might they have allowed independent states in lands where the Japanese are driven from, most obviously Indo China, possibly also Indonesia/ Dutch East Indies.
And does this prevent North Korea?
Query is Mao prevented from winning Civil War?
