I’m fine with waterboarding.
If you want to advocate war crimes, I can't stop you. Just be aware that your cheerful justification of the practice is setting up captured American soldiers for the same treatment.
And you break ranks with America's greatest generation.
From Wikipedia”
“In 1947, during the Yokohama War Crimes Trials, the United States prosecuted a Japanese civilian who had served in World War II as an interpreter for the Japanese military, Yukio Asano, for “Violation of the Laws and Customs of War”, asserting that he “did unlawfully take and convert to his own use Red Cross packages and supplies intended for” prisoners, but, far worse, that he also “did willfully and unlawfully mistreat and torture” prisoners of war. The charges against Asano included “beating using hands, fists, club; kicking; water torture; burning using cigarettes; strapping on a stretcher head downward.”[223] The specifications in the charges with regard to “water torture” consisted of “pouring water up [the] nostrils” of one prisoner, “forcing water into [the] mouths and noses” of two other prisoners, and “forcing water into [the] nose” of a fourth prisoner.[224] Asano received a sentence of 15 years of hard labor.”
