From a Bush speech in 2003:
The Convention Against Torture and Other Cruel, Inhuman or Degrading Treatment, ratified by the United States and more than 130 other countries since 1984, forbids governments from deliberately inflicting severe physical or mental pain or suffering on those within their custody or control. Yet torture continues to be practiced around the world by rogue regimes whose cruel methods match their determination to crush the human spirit.
As Andrew Sullivan points out, in the same speech he demands his own prosecution, by an international tribunal if necessary:
I call on all governments to join with the United States and the community of law-abiding nations in prohibiting, investigating, and prosecuting all acts of torture.
In another speech, Bush called himself a war criminal.
the people who mistreat the prisoners will be treated as war criminals
Not only is Bush anti-American, he suffers from Bush Derangement Syndrome.
Must be wunna them libruls.
