Frank Rich at the New York Times boils down why we tortured, and it's worse than we think. We tortured in particular to get info that linked Al Qaeda with Iraq, in order to justify going to war.
...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.
Last week Bush-Cheney defenders, true to form, dismissed the Senate Armed Services Committee report as "partisan." But as the committee chairman, Carl Levin, told me, the report received unanimous support from its members - John McCain, Lindsey Graham and Joe Lieberman included.
Levin also emphasized the report's accounts of military lawyers who dissented from White House doctrine - only to be disregarded. The Bush administration was "driven," Levin said. By what? "They'd say it was to get more information. But they were desperate to find a link between Al Qaeda and Iraq."
Five years after the Abu Ghraib revelations, we must acknowledge that our government methodically authorized torture and lied about it. But we also must contemplate the possibility that it did so not just out of a sincere, if criminally misguided, desire to "protect" us but also to promote an unnecessary and catastrophic war. Instead of saving us from "another 9/11," torture was a tool in the campaign to falsify and exploit 9/11 so that fearful Americans would be bamboozled into a mission that had nothing to do with Al Qaeda. The lying about Iraq remains the original sin from which flows much of the Bush White House's illegality.
If we are to remain proud to be Americans, we must see justice served here.
