There is a big difference between campaigning to change a treaty, and violating it.
Fair enough. How bout we just scrap the whole treaty, kick the UN out of our country, frog walk those Al Qaeda dogs down to the coast of Cuba, shoot them all in the head and let the sharks eat the evidence. I don't care what they call them- POWs, Nobel Peace Laureates or what. I want them to have a nice quick tribunal and a few hundred grams of lead in the brain.
