Killing people remotely with drones where you are at no risk , you do not experience the visceral impact of your act is the most cowardly  act a human being can do.  It is worse than killing and it is worse than  murder, it is EXTERMINATION.  The last government to practice this extermination as an official policy was the Hitler regime.  To do this without due process of law even on Americans and  With such callous disregard for human life that it is conducted with the same lack of precision we use when we spray bugs, is the worst obscenity in  American history.
