I commend to your attention Donald Rumsfeld: The War Crimes Case.
A few paragraphs:
Donald Rumsfeld was one of the primary architects of the Iraq war. On September 15, 2001, in a meeting at Camp David, Rumsfeld suggested an attack on Iraq because he was deeply worried about the availability of "good targets in Afghanistan." Former Treasury Secretary Paul O’Neill reported that Rumsfeld articulated his hope to "dissuade" other nations from "asymmetrical challenges" to U.S. power. Rumsfeld’s support for a preemptive attack on Iraq "matched with plans for how the world’s second largest oil reserve might be divided among the world’s contractors made for an irresistible combination," Ron Suskind wrote after interviewing O’Neill.
Rumsfeld defensively sought to decouple oil access from regime change in Iraq when he appeared on CBS News on November 15, 2002. In a Macbeth moment, Rumsfeld proclaimed the United States’ beef with Iraq has "nothing to do with oil, literally nothing to do with oil." The Secretary doth protest too much.
Prosecuting a war of aggression isn’t Rumsfeld’s only crime. He also participated in the highest levels of decision-making that allowed the extrajudicial execution of several people. Willful killing is a grave breach of the Geneva Conventions, which constitutes a war crime. In his book, Chain of Command: The Road from 9/11 to Abu Ghraib, Seymour Hersh described the "unacknowledged" special-access program (SAP) established by a top-secret order Bush signed in late 2001 or early 2002. It authorized the Defense Department to set up a clandestine team of Special Forces operatives to defy international law and snatch, or assassinate, anyone considered a "high-value" Al Qaeda operative, anywhere in the world. Rumsfeld expanded SAP into Iraq in August 2003.
But Rumsfeld’s crimes don’t end there. He sanctioned the use of torture and cruel, inhuman and degrading treatment, which are grave breaches of the Geneva Conventions, and thus constitute war crimes. Rumsfeld approved interrogation techniques that included the use of dogs, removal of clothing, hooding, stress positions, isolation for up to 30 days, 20-hour interrogations, and deprivation of light and auditory stimuli. According to Seymour Hersh, Rumsfeld sanctioned the use of physical coercion and sexual humiliation to extract information from prisoners. Rumsfeld also authorized waterboarding, where the interrogator induces the sensation of imminent death by drowning. Waterboarding is widely considered a form of torture.
This monster must be brought to justice.
