Perhaps, but we still sentenced people to prison for doing the exact same thing that we did.
Karl DÃnitz was sent to prison for sinking allied ships without warning, yet even at his trial, Admiral Chester Nimitz, wartime commander-in-chief of the U.S. Pacific Fleet, stated the U.S. Navy had waged unrestricted submarine warfare in the Pacific from the day the U.S. entered the war.
Sinking neutral ships without warning. Big difference. Plus there were all the other charges against him.
