WSJ Bret Stephens puts waterboarding in perspective.

"Oxygen starvation and carbon monoxide poisoning killed many; bomb shelters turned into ovens and roasted the persons inside, so that rescue workers days later found the bodies seared together in an indistinguishable mass; the molten asphalt of the streets engulfed those who fled the burning buildings."
An estimated 45,000 people died this way in Hamburg. U.S. and British air forces would repeat the procedure over Dresden, Tokyo, Yokohama, Hiroshima, Nagasaki--"

And that's what happened during the "good" war when a Democrat was in charge. At least he was grown-up about all this.
