In July, 1950, during the Korean War, US forces holding a bridge at No Gun Ri shot, shelled, and called in airstrikes on refugees attempting to flee advancing communist forces. In the process, several hundred innocent civilians were killed. When the massacre was revealed in 1999, a US Army inquiry found that the killings were an "unfortunate tragedy" due to panicky soldiers, rather than the result of a deliberate policy. But now evidence has come to light which undermines that conclusion. A US historian, Sahr Conway-Lanz, has discovered a letter from the US Ambassador to Seoul to the US State Department reporting on decisions made at a high level meeting of American officials the day before the killings began. One of those decisions was a deliberate policy to shoot refugees:
"If refugees do appear from north of US lines they will receive warning shots, and if they then persist in advancing they will be shot," wrote the ambassador, John J Muccio, in his message to the Assistant Secretary of State, Dean Rusk.
This is nothing less than a policy of deliberate, cold blooded murder. Unfortunately, I doubt that any of those responsible will still be alive to face prosecution for it.
