I’m not positive but I’m pretty sure they thought the land would be opened up for the Americans after the war but that was not the case and they were mad about that
Waterfall. <span>As the river or stream wears away the weak rocks, they travel across the surface of stronger rocks. These more resistant rocks become the capstones to waterfalls. The number and thickness of these stronger rock units in a vertical sequence of rocks controls how many water falls there are and how much vertical drop there is on each waterfall.</span>
When Japan fell during the Second World War, Korea was suddenly free, and hoped to finally be able to decide the fate of their own country. Most Koreans campaigned for a unified state.
However, the United States and the Soviet Union had different ideas. The Soviets wanted to expand the sphere of communist influence into Korea. The United States countered by encouraging the establishment of democracy. Additionally, the United States stressed the importance of containment, which is a foreign policy used to prevent the spread of communism.
This disagreement would eventually lead to the Korean War. The Korean War was the first battle of the Cold War, and first major proxy war fought between the United States and a Soviet communist supported enemy. A proxy war occurs when one or more opposing powers instigates a war and then uses third parties to fight on their behalf.
I believe it is the installment plan. :)
