Answer:
B) North Koreans, with Stalin's approval, invaded South Korea .
Explanation:
The communist leader of North Korea, Kim Il-sung, conceived the idea to lauch a war and reunite Korea by force. Soviet great leader Joseph Stalin approved the plan. Both miscalculated. They thought it wouldn´t prompt a strong American reaction (the Cold War had already started), because Korea was not deemed as strategic then and continental China had fallen in communist hands just months before. Washington thought it was an elaborate plan of communist expansion in Asia, which was not really the case. The North Korean army invaded the South in 1950 and thus the Korean War began.
