He wielded US power for the purpose of undoing the Geneva Conventions and the UN Convention on Torture, and we now learn, he was eager to reverse long-standing US policy to prevent the "disappearances" of suspects:

From 2003 to 2006, the Bush administration quietly tried to relax the draft language of a treaty meant to bar and punish "enforced disappearances" so that those overseeing the CIA's secret prison system would not be criminally prosecuted under its provisions, according to former officials and hundreds of pages of documents recently declassified by the State Department.

The aim of the global treaty, long supported by the United States, was to end official kidnappings, detentions and killings like those that plagued Latin America in the 1970s and 1980s, and that allegedly still occur in Russia, China, Iran, Colombia, Sri Lanka and elsewhere. But the documents suggest that initial U.S. support for the negotiations collided head-on with the then-undisclosed goal of seizing suspected terrorists anywhere in the world for questioning by CIA interrogators or indefinite detention by the U.S. military at foreign sites.
