They're not so keen on torture (from Armed Forces Journal):
Let AFJ be crystal clear on a subject where these men are opaque: Waterboarding is a torture technique that has its history rooted in the Spanish Inquisition. In 1947, the U.S. prosecuted a Japanese military officer for carrying out a form of waterboarding on a U.S. civilian during World War II.
Waterboarding inflicts on its victims the terror of imminent death. And as with all torture techniques, it is, therefore, an inherently flawed method for gaining reliable information. In short, it doesn’t work. That blunt truth means all U.S. leaders, present and future, should be clear on the issue.
