Torture is an impermissible evil. Except under two circumstances. The first is the ticking time bomb. An innocent's life is at stake. The bad guy you have captured possesses information that could save this life. He refuses to divulge. In such a case, the choice is easy. Even John McCain, the most admirable and estimable torture opponent, says openly that in such circumstances, "You do what you have to do." And then take the responsibility.

Some people, however, believe you never torture. Ever. They are akin to conscientious objectors who will never fight in any war under any circumstances, and for whom we correctly show respect by exempting from war duty. But we would never make one of them Centcom commander. Private principles are fine, but you don't entrust such a person with the military decisions upon which hinges the safety of the nation. It is similarly imprudent to have a person who would abjure torture in all circumstances making national security decisions upon which depends the protection of 300 million countrymen...

...Today Pelosi protests "we were not -- I repeat -- were not told that waterboarding or any other of these other enhanced interrogation methods were used." She imagines that this distinction between past and present, Clintonian in its parsing, is exonerating.

On the contrary. It is self-indicting. If you are told about torture that has already occurred, you might justify silence on the grounds that what's done is done and you are simply being used in a post-facto exercise to cover the CIA's rear end. The time to protest torture, if you really are as outraged as you now pretend to be, is when the CIA tells you what it is planning to do "in the future."

But Pelosi did nothing. No protest. No move to cut off funding. No letter to the president or the CIA chief or anyone else saying "Don't do it."...

...It is one thing to have disagreed at the time and said so. It is utterly contemptible, however, to have been silent then and to rise now "on a bright, sunny, safe day in April 2009" (the words are Blair's) to excoriate those who kept us safe these harrowing last eight years.
