All War-All The Time by William Blum

One observer has summed up the legal arguments put forth by the Bush administration thusly: "The existing laws do not apply because this is a different kind of war. It's a different kind of war because the president says so. The president gets to say so because he is president. ... We follow the laws of war except to the extent that they do not apply to us. These prisoners have all the rights to which they are entitled by law, except to the extent that we have changed the law to limit their rights."
