In case you had doubts

New York Times:

...in tracing responsibility for what went wrong at Abu Ghraib, [the four-member panel headed by James M. Schlesinger] drew a line that extended to the defense secretary's office.

The panel cited what it called major failures on the part of Mr. Rumsfeld and his aides in not anticipating and responding swiftly to the post-invasion insurgency in Iraq. On the eve of the Republican convention, that verdict could not have been welcome at the White House, where postwar problems in Iraq represent perhaps President Bush's greatest political liability.

Beginning in late 2002, the panel said, Mr. Rumsfeld and his staff set the stage for an environment in which abuses later became widespread. They did this first by sowing confusion about what kinds of interrogation techniques would be permitted, then by failing to plan for the intensity of the post-invasion insurgency, and finally by delaying for months in dispatching reinforcements to help the American guards at Abu Ghraib contend with the swelling number of prisoners.
