The original statistics for the Korean War was 54,260 US Military killed. During the Clinton administration the statistics were revised by the DOD down to around 34,000. Unlike past and future conflicts where every Military death including accidents and disease was included, the "new" statistics for Korea would only include Americans killed in battle on the Korean peninsula. The question remains how did the other 20,000 Americans die between 1950 and 1953? Coincidentally the US was conducting Nuclear tests in the Marshall Is. during the Korean war. From 1946 - 1958 23 nuclear tests were conducted. The problem was that the Military apparently didn't touch bases with the scientists or the scientists weren't aware that the sites were deadly. The US Military actually posted Soldiers and Sailors close to the tests and even had Sailors board ships that were dangerously radioactive and deadly. My guess is that the DOD doesn't want to include the members of the Military who were killed in Atomic testing in the numbers of KIA during the Korean War for some obscure political reason.
