Korea and Communists Just five years after the end of the Second World War, America is stunned to learn that communists have somehow managed to gain control of China. At the same time, communists supported by the Soviets are attempting to gain control the entire Korean peninsula, while communists in Vietnam supported by China are gradually pushing out the French.

	New Threat This is what Asia looks like to American military planners. The RED and ORANGE areas on the map, controlled by communist governments, are immense. Actually, far more than half of this communist zone is barely inhabited. Siberia, Mongolia and much of western China are nearly vacant. Even so, alarm bells are ringing all over Washington. The small BLUE area in South Korea indicates the tiny patch of non-communist Korea remaining before US forces arrive to push back.
	Limits of Power America's anti-communists juices are now in full flow. President Truman sends Americans into Korea, to prevent communists from taking control of the entire country. But after the Americans succeed in pushing the communists north, almost to the Chinese border, China suddenly feels compelled to intervene. It sends vast swarm of Chinese troops over the border to help expel the western 'imperialists.' After bitter fighting in difficult terrain, America is forced to settle for a stalemate, with borders unchanged.
