Indo China

Explanation:

Right after the end of WWII, France was involved in an armed conflict in the region known as Indo China (mostly in Vietnam, although the fighting spread to neighboring countries, Laos and Cambodia). Later, after the French left having met nothing but failed attempts at stopping the spread of communism in the region, the USA took over the war effort and supported militarily South Vietnam as they fought the North, mainly backed by the Soviet Union, China, and other communist allies. The war, which France had begun in 1946, ended in 1975 with the fall of Saigon and  North Vietnam declaring victory.
