FDR was very supportive of an invasion of Hainan Island and Indochina as a way to create a secure route to supply the Chinese that didn't involve flying over Burma, despite the fact that all of the military leaders in the Pacific theater were against the plan. What if FDR gets what he wanted and the United States end up invading the island and north Vietnam. FDR was in favor of a Chinese trusteeship over Vietnam, a position that alienated the British and the French, so does the presence of US troops in Vietnam give any viability to FDR's plan and if the French never get Indochina back what's this going to mean for Franco-American relations in the Cold War?
