The mantra from the left during the Bush years went something like this: The world is not black and white. Sophisticated minds should seek out different, nuanced opinions.

Now that Barack Obama is president, you can say a farewell to nuance. The left chants, "torture doesn't work" -- defining waterboarding and sleep deprivation as torture. Obama has a longhand version of that mantra in his rejection of the "false choice between our security and our ideals."

In Obamaland, somehow there never are difficult choices. From the presidency that was supposed to promote intellectualism comes the argument that waterboarding is immoral -- which is a fair argument to make, until its adds: and it doesn't work.

But common sense tells you that techniques like sleep deprivation, waterboarding and a forced bland diet work, at least some times.

Khalid Sheikh Mohammed (aka KSM) didn't exactly want to help the CIA. Yet Americans are supposed to believe that asked-nicely interrogations yielded or would have yielded the same information as "enhanced techniques" designed to inflict extreme discomfort and dread?

As I reported last week, the newly released Bush administration memos credited the use of waterboarding and other methods with leading to the discovery of a planned "second wave" attack on Los Angeles and other terrorist plans. But there are contradictions in the official accounts of when that L.A. attack was foiled. At one point, the Bush White House had claimed the plot was discovered and interrupted in 2002 -- the year before Mohammed was captured.

Even if that Los Angeles claim does not stand up -- and we don't know at this point -- we do know that former CIA chiefs George Tenet (a Clinton appointee) and Porter Goss believe the "enhanced techniques" program worked. OK, you say: They supported waterboarding, so of course they say it worked. But Obama's director of national intelligence, Dennis Blair, a critic of the use of the "enhanced techniques," also said they yielded "high-value information."

Blair, however, maintains that the information was not worth the damage to America's image. I guess it is a sign of the modern age that U.S. forces can deploy unmanned drones to attack the enemy in Afghanistan -- risking the lives of innocent people, among whom the guilty are hiding -- but the left gets its hackles up if KSM loses his beauty sleep.
