Was America successful in the Korean War?
It was successful in containing communism, but not successful in achieving their goal of eliminating it entirely.
The Korean War WAS SUCCESSFUL! South Korea today is a very successful producer of automobiles, computers, televisions, and other fine products. South Korea's STANDARD of living is higher than many countries within the Asian Hemisphere. The communists were STOPPED at the 38th Parallel. That Parallel still exists today.
