Which of these was a cause of the korean war (1950-1953)?
a) south korea invaded north korea.
b) north korea blockaded goods from south korea.
c) south korea became an ally of the soviet union.
d) north korea embraced communism while south

The correct answer is D) North Korea embraced communism while South Korea embraced capitalism.

After the Second World War, Japanese troops withdrew from the Korean peninsula and it was occupied by the Soviet troops in the North and by the US troops in the South. With the beginning of the Cold War the two powers failed to create a united Korea, therefore when they retired from the peninsula at the end of the 1940's they established a border drawn on the 38th parallel that divided communist North Korea from capitalist South Korea. In 1950, North Korea, with the support of the Soviet Union and China, invaded South Korea in an attempt to gain control over the entire peninsula, which caused the intervention of the United States, and thus initiating the Korean War.
