USA HISTORY

Detailed explanation-1: -For five years during World War II, Indochina was a French-administered possession of Japan.

Detailed explanation-2: -The Japanese military entered Vietnam in September 1940 and remained there until the end of World War II (August 1945). French colonial administrators remained in charge for most of this period, until the Japanese assumed control in 1945.

Detailed explanation-3: -And here’s where World War II changed Vietnam forever. In 1940, the German army sliced through France like butter. Germany’s ally, Japan, eventually invaded Vietnam and replaced the French as colonial masters. Vietnam was now a Japanese colony, and that put it squarely in the crosshairs of US foreign policy after 1941.
