This was admitted by the State Department itself in a recent report. It detailed an array of human rights abuses last year by the Iraqi government, including torture, rape and illegal detentions by police officers and functionaries of the interim administration that took power in June. It cited "reports of arbitrary deprivation of life, torture, impunity, poor prison conditions - particularly in pre-trial detention facilities - and arbitrary arrest and detention."
While the report has some harsh words for the interim Iraq government's human rights record, it states the US puppet regime "generally respected human rights, but serious problems remained"! Does that mean a verbal commitment by a client regime is what counts as respecting human rights rather, than say, not torturing or raping people?
Strangely enough, the State Department report, while happy to attack Iraqi abuses, fails to mention American ones. It ignores the war crimes committed at Abu Ghraib and elsewhere (in Iraq and around the globe).
