I suggest you look back at history. The U.N first became involved in Korea on June 25, 1950 (the same day North Korea invaded South Korea), when it passed the U.N. Security Counsel Resolution 82 which demanded that North Korea cease its invasion of South Korea. The U.S. and KPA forces didn't fight their first battle until the Battle of Osan, which started on July 5, 1950, a full 10 days after the Resolution passed. The U.N. also passed Resolution 83, which asked for members of the U.N. to send forces to aid South Korea, on June 27, 1950.
So it was, in fact, the U.N. that was involved with Korea before the U.S. Also, it wasn't a "long before" timeframe, there was 10 days between North Korea invading South Korea and the first fight between KPA forces and the U.S. military.
