Waterboarding Was Defined As A War Crime In 1947

From The Washington Post.

Twenty-one years earlier, in 1947, the United States charged a Japanese officer, Yukio Asano, with war crimes for carrying out another form of waterboarding on a U.S. civilian. The subject was strapped on a stretcher that was tilted so that his feet were in the air and head near the floor, and small amounts of water were poured over his face, leaving him gasping for air until he agreed to talk.
