Marty believes that rightous condemnation of his justification of criminal stance is ad hom and somehow excuses him? No, jihadists do not lose the protections of the law of war at all, marty, when they break them. That is not the law, although you can post the evidence if you think you have it. Jihadists, and you if you do it, are taken by the laws of war, treated accordingly by the laws of war, tried by the laws of war, and, if guilty, executed by the laws of war.
Thank heavens for the UCMJ that would condemn and prosecute and punish you if you did such things to those taken prisoner.
