Sorry Bill, but I think you've made a fundamental error. The decisions were with how to run the Tribunals. Not on how to act in the war zone. The tribunals are being held in a safe area, years after the initial 'arrest'. No one, so far as I've heard, has said that the combat troops on the ground have to read anyone their rights.

So, the decisions revolve not around the standards we expect our troops to follow, but around the standards we expect the courts to adhere to. I'll cut a lot of slack for the people in a war zone. I, and the SCOTUS, won't cut much slack for a judge and lawyers in a court room.

As to the Geneva Conventions, I'd refer you to John McCain's rather forceful reply to G.W. Bush on the subject. Well, I would if I could find a quote. It was along the lines of "We don't do it so that our people aren't subjected to it".
