North korea respond
On June 25, 1950 the North Korean army attacked South Korea, crossing the 38th Parallel. Pentagon officials were stunned, and had no immediate contingency plan ready. Some said little could be done, while others suggested it was the beginning of Stalin's plot to take over the world. Truman and his circle of advisers sat firmly in this latter group. Immediately upon the invasion, these advisors discussed the prospect of sending General Douglas MacArthur, the US commander in the Far East, to lead a military response. The North Korean invaders hoped to take Seoul, the South Korean capital, as quickly as possible. The majority of ROK forces were routed by North Korean troops. Only one ROK division, the 6th, held its ground. John Muccio, the American ambassador to South Korea, quickly reported back to Washington that a "probable" full-scale attack was under way. Meanwhile, Syngman Rhee reacted to news of the invasion by ordering the imprisonment of more South Koreans.
The UN was particularly upset about the North Korean invasion, because it had overseen the elections held in 1948, and did not want to see a war undo that election. UN Secretary-General Trygve Lie called the invasion a "war against the United Nations." Truman hoped to use the UN as an instrument of US power, and UNCOK (the UN Council on Korea) condemned the attack as a "breach of peace". On Nov. 30, 1950, the UN passed a resolution condemning North Korea's actions.
There were points where it seemed they were so close to winning and so close to losing. North Korea's leader Kim Il Sung wanted to unite all of Korea under communism, so he launched a surprise attack on South Korea.

implications
I think that NK was the main aggressor in the Korean war because it seemed to be the enemy. NK was also standing because of China helping them. Without NK, there would not have been a Korean War, or as much of a Cold War.
