Answer: EASTERN EUROPE
Context/explanation:
US president Franklin Roosevelt, British prime minister Winston Churchill, and Soviet premier Joseph Stalin, the leaders of the Allies in World War II, met at Yalta in February, 1945.
Churchill and Roosevelt pushed strongly for Stalin to allow free elections to take place in the nations of Europe after the war. At that time Stalin agreed, but there was a strong feeling by the other leaders that he might renege on that promise. The Soviets never did allow those free elections to occur. Later, Winston Churchill wrote, ""Our hopeful assumptions were soon to be falsified." Stalin and the Soviets felt they needed the Eastern European nations as satellites to protect their own interests. A line of countries in Eastern Europe came into line with the USSR and communism. Churchill later would say an "iron curtain" had fallen between Western and Eastern Europe.
Secession is when a state decides to withdraw from the Union.
1. General MacArthur had a successful surprise attack launched on the North Korean army at Inchon, which was west of the Korean Peninsula. When he met with Truman face to face at Wake Island, he publicly accused the president of "appeasement" regarding China. Instead of following Truman's orders, MacArthur did things his way. He thought that the Chinese would not join in the war, so he assured Truman that the Chinese army would not take part in the war when the UN forces reach the Yalu River, the border between China and North Korea. MacArthur was so confident in his success that he promised American troops would be home for Christmas.
2. President Truman assigned General MacArthur as leader of the UN troops. Truman's overall objective was to create harmony between North and South Korea as soon as possible. He was concerned of the Chinese army joining in the war in favor of North Korea, but MacArthur assured him that the Chinese would not interfere when they reach the Yalu River; however, he was wrong. Because MacArthur disobeyed the orders, Truman relieved MacArthur of his position.
3 and 4 are based on your own opinions, so I cannot answer that part. Otherwise, hope this helps a little though it is not much.
Feudalism allowed large territories to be governed in the absence of a central government. Each lord or vassal raised an army to defend his fief and to serve the king as needed. One drawback to this system was that the nobles were very powerful because they controlled the armies.
