Question

What caused the Korean War?

Answer 1

Before World War II , Japan controlled all of Korea. However, in 1941, the U.S, and Russia declared war on Japan. The Japanese surrendered in 1945. So, Russia and the U.S. decided to divide Korea, and the U.S. got South Korea and Russia got North Korea. The two sides set up their own government, however, both sides were intent on uniting the two sides as one. North Korea wanted to set it up their own way and South Korea wanted to set it up their own way.
North Korea had a large military and big support from the Russians. South Korea had a small military and only a little support from the U.S. North Korea knew that if they invade South Korea , they would be able to conquer them and reunite Korea and set up their own government and way of life. With this idea in mind, North Korea chose the way of war and their means to reunite Korea under their control.
