Background
Korea became a Japanese colony in 1905 after the Russo-Japanese War and was divided into two regions after World War II, with the Soviet Union controlling the North and the United States controlling the South.http://www.sparknotes.com/history/american/koreanwar/section1.html The regions became two separate nations in 1948.
The invasion of South Korea was an attempt to reunify the two regions into one nation by bringing the South under the control of North Korea's government and its leader Kim II Sung. Several nations held an interest in the outcome, including the Soviet Union, which supported the communist regime in the North, and the United States, which was determined to prevent a communist victory over the South.http://www.history.com/reference/encyclopedia/viewArticle?id=214043&networkCode=THC]
Korean Armistice Agreement
On July 27, 1953, North and South Korea officially signed the Korea Armistice Agreement to end the fighting between the countries. The agreement did not favor either country, both sides were given their own, independent nations and a military boundary line was drawn between the two nations. All of the other countries in the war at the time also withdrew from the nations, and both sides immediately halted any combat on the field.http://news.findlaw.com/wp/docs/korea/kwarmagr072753.html
Korean War Air Battles
During World War II, which took place a decade before the Korean War, warfare through the air really began to take shape during battles for the first time. This would carry over into the Korean War, as both sides would use bombs to try and hurt opposing armies from behind enemy lines.
