The sad truth is that none of these treaties are worth the paper they are printed on. There are more treaties that claim to protect rights than I can shake a stick at. Yet none of them stopped a dozen EU states from helping Uncle Sam kidnap, transport, imprison, and torture anyone he decided was an Evildoer.
I don't remember any EU government brought down over the CIA kidnap-and-torture program. I don't recall anyone going to prison over this. I don't recall any mass protests, although maybe there were, and they were buried by the media.
I do recall that polls consistently show Americans supporting torture. America has certainly earned all the chickens that are coming home to roost. One can not set the world on fire and not get burned.
