General MacArthur- Wanted: To provoke and aggravate China. But...He was commanded not to pass the 20 mile mark. So...He went and crossed the 20 mile mark anyway, showing that he wasn't scared.

President Truman- Wanted: To discontinue the soviet development, try to make the war cease, and even tried to discontinue communism expansion. But....The Americans decided that they didn't want to go into combat. So...the war ended like a chess game and ended in stalemate.

China- Wanted: A safe zone, so that no country could interfere with the refurbishment. So.....China actually organized a planned attack that defeated the troops of amazing. But...China worried that the united states would go into their country, if both the united states and Korea were allowed in combat.

United Nations- Wanted: 
To basically make communism CEASE!! But... General MacArthur continued to past the 20 mark mile. (grr macarthur so stubborn) Despite the fact he was told NOT to by both the UN and Truman.  So...
