To clarify my position:
IMHO:
SOME of the Gitmo detainees are POWs. They should be treated as POWs. They were captured during the war on either the Taliban or during the war against insurgents in Iraq. They should be treated as POWs, and eventually repatriated to the governments of Iraq / Afghanistan. It is SOP in the world to keep POWs locked up until a war is over.
SOME of the Gitmo detainees are prisoners of the War on Terror. We need to determine what the correct legal path is for these people. The standard US criminal court is not designed for these types of crimes, nor are the rules of evidence, etc.
SOME of the Gitmo detainess are Unlawful Combatants, an area that has not been deeply explored. That used to be the category for spies and others fighting without a uniform. A member of my family spent time in a German camp for spies after he was captured behind the lines. His treatment was not at the same level as regular POWs, and that was expected given the circumstances of his capture. We now have more than just spies being picked up, and that is messing with our regular operating rules.
After we separate the detainees into those two (or three?) camps, we have the additional issue of what to do with them after either the war is over or their sentence has been served. If we dump them back to some of their origin nations, they will probably be executed. If we let them go someplace neutral, many will show up fighting us again. This MUST be considered, and can not be just hand waved away.
I am all for human rights, for treating prisoners properly (even when my opponents do not give me same consideration), and I believe the research that shows that torture does not get you a lot in terms of decent information.
I blame Truman and Johnson for the “police actions” of Korea and Vietnam where we started muddying the waters around the definitions of War vs. Crime. Calling it the “Cold War” did not help, and it only opened the door to the “War on Terror.”
