haha wow... the info about the liberty building attack was delivered 6 months before we began waterboarding.
And, abu zubadia gave all his actional intel - BEFORE he was waterboarded. Once he was soaked, there was no more info.
Finally - in the mother of all ironies -
The japanese waterboarded our GIs in WW2 to find out info about... WMD. Ironic that we nuked them a few months later. And, when we won the war, we imprisoned or executed the japanese bastards who were doing the waterboarding.
