[W]e do have evidence for an alternative explanation of what motivated Bybee to write his memo that August, thanks to the comprehensive Senate Armed Services Committee report on detainees released last week.

The report found that Maj. Paul Burney, a United States Army psychiatrist assigned to interrogations in Guantánamo Bay that summer of 2002, told Army investigators of another White House imperative: “A large part of the time we were focused on trying to establish a link between Al Qaeda and Iraq and we were not being successful.” As higher-ups got more “frustrated” at the inability to prove this connection, the major said, “there was more and more pressure to resort to measures” that might produce that intelligence.

In other words, the ticking time bomb was not another potential Qaeda attack on America but the Bush administration’s ticking timetable for selling a war in Iraq; it wanted to pressure Congress to pass a war resolution before the 2002 midterm elections. Bybee’s memo was written the week after the then-secret (and subsequently leaked) “Downing Street memo,” in which the head of British intelligence informed Tony Blair that the Bush White House was so determined to go to war in Iraq that “the intelligence and facts were being fixed around the policy.” A month after Bybee’s memo, on Sept. 8, 2002, Cheney would make his infamous appearance on “Meet the Press,” hyping both Saddam’s W.M.D.s and the “number of contacts over the years” between Al Qaeda and Iraq. If only 9/11 could somehow be pinned on Iraq, the case for war would be a slamdunk.

But there were no links between 9/11 and Iraq, and the White House knew it. Torture may have been the last hope for coercing such bogus “intelligence” from detainees who would be tempted to say anything to stop the waterboarding.
