Twin vets return to South Korea

You really don't know your history. After the 38th parallel was established as the point dividing the 2 Koreas the north invading the south. This was not something that the north just decided to do. It was at the encouragement of China and Russia. That is why there was a UN resolution established to send forces into the south. The American forces that first on the ground were under armed and out gunned but still killed about 150 North Koreans but suffered about the same losses. This was the first proxy war between Communist Russia and America. If as you claim the war was none of our business and the communist would have won in Korea they surely would have rolled over Japan and then Hawaii and then mainland America. So yes during that time in our history it was America’s duty to help other non Communist countries to deter Communist aggression and oppression. Vietnam was the same scenario, just that American people had pretty much the same attitude as you, “it’s not our business”. That lack of support doomed our soldiers to failure.
