But Bush's legacy is one of much more wanton and widespread cruelty -- a cruelty that was truly unimaginable before the unique combination of 9/11 and some particularly cold-blooded people occupying high office.
Bush and his helpers approved a wide range of other brutal interrogation practices, including severe beatings, painful stress positions, severe sleep deprivation, exposure to extreme cold and hot temperatures, forced nudity, threats, hooding, the use of dogs and sensory deprivation -- many of which, it turned out, were cribbed from techniques Chinese Communists perfected to extract confessions from captured U.S. servicemen.
Some of these tactics fall short of the legal definition of torture, some don't, but they are all, as former Navy general counsel Alberto Mora explained in 2008, morally indefensible:
Many Americans are unaware that there is a legal distinction between cruelty and torture, cruelty being the less severe level of abuse. This has tended to obscure important elements of the interrogation debate from the public's attention. For example, the public may be largely unaware that the government could evasively if truthfully claim (and did claim) that it was not "torturing" even as it was simultaneously interrogating detainees cruelly. Yet there is little or no moral distinction between cruelty and torture, for cruelty can be as effective as torture in savaging human flesh and spirit and in violating human dignity. Our efforts should be focused not merely on banning torture, but on banning cruelty.
Tactics that violated basic human dignity were not limited to three men, or even to the three dozen men subjected to "enhanced interrogation" at the CIA's black sites in Poland, Thailand, and Romania. They were employed as a matter of standard practice on countless detainees held in custody in Afghanistan, Iraq and Guantanamo Bay.
And once cruelty was adopted as a weapon of war, that inevitably opened the door wide to abusive and degrading practices that weren't explicitly authorized.
Far from being limited to ostensibly "high value" detainees, state-sanctioned cruelty was applied willy-nilly to many of those unfortunate enough to get swept up into the system. We literally have no idea how many.
As a bipartisan Senate report in 2008 concluded:
The abuse of detainees at Abu Ghraib in late 2003 was not simply the result of a few soldiers acting on their own. Interrogation techniques such as stripping detainees of their clothes, placing them in stress positions, and using military working dogs to intimidate them appeared in Iraq only after they had been approved for use in Afghanistan and at [Guantanamo]. Secretary of Defense Donald Rumsfeld's December 2, 2002, authorization of aggressive interrogation techniques and subsequent interrogation policies and plans approved by senior military and civilian officials conveyed the message that physical pressures and degradation were appropriate treatment for detainees in U.S. military custody. What followed was an erosion in standards dictating that detainees be treated humanely.
The report laid out a clear line of responsibility for Abu Ghraib that started with Bush and his February 2002 memo exempting war-on-terror detainees from the Geneva Conventions.
Mora, one of the few voices of conscience inside the government during that dark period, summed up the damage this way:
[O]ur Nation's policy decision to use so-called "harsh" interrogation techniques during the War on Terror was a mistake of massive proportions. It damaged and continues to damage our Nation in ways that appear never to have been considered or imagined by its architects and supporters, whose policy focus seems to have been narrowly confined to the four corners of the interrogation room. This interrogation policy -- which may aptly be labeled a "policy of cruelty" -- violated our founding values, our constitutional system and the fabric of our laws, our over-arching foreign policy interests, and our national security. The net effect of this policy of cruelty has been to weaken our defenses, not to strengthen them, and has been greatly contrary to our national interest.
George W. Bush has managed to duck the ignominy he deserves for launching this policy of cruelty. He has done so in part by framing the debate as one solely about waterboarding -- and counting on a lazy, amnesiac press corps to neither confront him on that count nor call him out for the wider moral breach for which he is responsible.
Back in 2004, as soon as the photos of detainee abuse at Abu Ghraib went public, Bush and his collaborators launched a high-stakes disinformation campaign to prevent the American people from linking the White House to the pervasive, inhumane treatment of detainees -- many of whom were utterly innocent -- at prison facilities such as Abu Ghraib, Bagram, and Guantanamo. Being associated with the waterboarding of three top terrorists was at least a defensible position. Being responsible for widescale violations of the laws of war was not.
That disinformation campaign continues today, in "Decision Points." If we forget what really happened, it just might succeed.
