OTL’s Korean War had consequences on the geopolitical landscape of East Asia stretching throughout the Cold War, and obviously into today. From the PRC being left out of the UN for two decades, to the boost that Japan got from being a US staging ground for the war, to the conflict serving partly as a precedent for US involvement in Vietnam, and the continued division of the Korean Peninsula lasting to the present.
What are some of the alternate ways in which the broader Asia-Pacific region can develop in a scenario where Kim Il-Sung and co don’t launch their war? Would the Yanks still stick to Chiang Kai-Shek and stonewall the PRC’s entry to the UN? Does the Domino Theory have as much weight, depending on how Vietnam goes? And how do the domestic politics of the two Koreas, as well as Japan, China and Southeast Asian countries, develop?
