A major hostility breaks out in the Korean peninsula. The North and South are at it. The US presence there is large. We know that Chinas best is positioned near the Koreas and it faces a grim situation during thst war there. Seeing the Chinese involved in Korea, India sees it as the time to take back lost territory and attacks those areas. Taiwan sees this opportunity as the right time to declare independence. All hypothetical, but how would the Chinese face up these three fronts?
