While prisoners of war can be theoretically stripped of their rights by calling them other names (like "unlawful combatants"), they are probably most effectively stripped of all rights by keeping their imprisonment secret. That is what Rumsfeld says he did.
An account of what we know on this matter can be found on page 110 of a new report by Congressman John Conyers called "The Constitution in Crisis; The Downing Street Minutes and Deception, Manipulation, Torture, Retribution, and Cover-ups in the Iraq War."
Following a catalog of evidence of other crimes sanctioned by top Bush Administration officials, the report reads:
"Q -- Mr. Secretary, I'd like to ask why last November you ordered the U.S. military to keep a suspected Ansar al-Islam prisoner in Iraq [Hiwa Abdul Rahman Rashul] secret from the Red Cross. He's now been secret for more than seven months. And there are other such shadowy prisoners in Iraq who are being kept secret from the Red Cross.
"SEC. RUMSFELD: With respect to the -- I want to separate the two. Iraq, my understanding is that the investigations on that subject are going forward. With respect to the detainee you're talking about, I'm not an expert on this, but I was requested by the Director of Central Intelligence to take custody of an Iraqi national who was believed to be a high-ranking member of Ansar al-Islam. And we did so. We were asked to not immediately register the individual. And we did that. It would -- it was -- he was brought to the attention of the Department, the senior level of the Department I think late last month. And we're in the process of registering him with the ICRC at the present time . . ."
This is the Secretary of Defense publicly stating that the Director of the CIA told him not to register a prisoner with the Red Cross, and that he obeyed, and that several months later the prisoner was still not registered.
Why do Nuremberg Principles III and IV both come to mind?
The fact that a person who committed an act which constitutes a crime under international law acted as Head of State or responsible Government official does not relieve him from responsibility under international law.
The fact that a person acted pursuant to order of his Government or of a superior does not relieve him from responsibility under international law, provided a moral choice was in fact possible to him.
Why was the CIA calling the shots here? Because they had taken Mr. Rashul out of Iraq for "questioning" at an undisclosed location. They were transferring him to military custody.
General Sanchez issued his own order to implement Secretary Rumsfeld's order. Sanchez' order, as reported in the media, "accepts custody and detains Hiwa Abdul Rahman Rashul, a high-ranking Ansar al-Islam member;" orders that he "remain segregated and isolated from the remainder of the detainee population;" "[o]nly military personnel and debriefers will have access to the detainee. . . . Knowledge of the presence of this detainee will be strictly limited on a need-to-know basis." "Any reports from interrogations or debriefings will contain only the mininum [sic] amount of source information . . ."
The ghosting of Rashul can neither be blamed on low-ranking personnel nor be described as an isolated incident.
