The Cold War was cold for a reason, apparently MAD wasn't an attractive option and bizarrely, "cool" head prevailed.
On the ground, in a battlefield ... I just kind of think, all bets are off. It takes on a life of its own.
Within a government, yes, I could say, we will hold our troops accountable. But if the Germans in WWII summarily executed an escaped POW - they could see it as entirely justified, an unacceptable risk, and I'm not sure I would call it a war crime.
Or if the Americans nuked Japan saying that was the only way to end the war and 100,000+ civilians died how are our actions not a war crime?
It's fine for me to see the suit against Rumsfeld go forward.
I agree with most of what you say here, but none of it supports your argument that we shouldn't have a Convention Against Torture, or that it's somehow unrealistic.
FWIW, war crimes are about violence against non-combatants during times of war (see the 4th Geneva Convention), whereas the Convention Against Torture applies at all times. I think maybe you are imagining that torture is a war crime, and that's why you think it's silly to make rules of war.
The Convention Against Torture is an agreement among signatory nations not to commit torture, which is defined as the intentional infliction of pain (physical or mental) by an agent of the government on a person in custody for the purpose of punishment or to extract a confession or other information. Whether or not we are war, cold or hot, is irrelevant.
I was merely comparing the deterrent effect with MAD during the Cold War. It is possible to make and abide by treaties and conventions with people we consider "enemies". In fact, those are by far the most important ones to make! The mutual deterrent is what makes such adherence to these agreements such a good idea.
And I think it's perfectly realistic to think that nations, especially our own,
should abide by the terms of these treaties.
The biggest problem I see with the Convention Against Torture is that it was non self-executing and required signatory nations to pass their own laws within a period of time that would execute the terms of the treaty. In doing so (in U.S. signing and ratification reservation statements as well), the U.S. effectively re-defined torture.
Even so, plenty of what has gone on would still satisfy even the narrower definition. (According to Dubya's legal advisors, the definition required pain that was equivalent to that of organ failure and death, for example. Since some of the people were tortured to death, we have violated even this definition.)
So the biggest problem is that criminal prosecution still requires the political will to do it. Obama and A.G. Holder are unwilling to investigate and prosecute those who clearly violated the CAT.
So the best we can get are civil suits, meaning Rumsfeld will never be found guilty of the crime of torture, and will never face prison for that crime.
