Did al-Awlaki plan, authorize, or commit the terrorist acts that occurred on  September 11? Well, no, but al-Qaeda  did – and since the departed Muslim cleric is said to be “linked”  to that nearly  defunct organization, one could make a tenuous argument that the resolution  covers this instance. Yet one runs up against the question of whether the  killing of an American citizen without benefit of due process really is  “necessary and appropriate.” The Obama administration could argue it was  necessary – but appropriate? I don’t think so, at least not without issuing a  formal indictment, which is one legal nicety they didn’t bother with. In any  case, Congress cannot grant the President the “right’ to kill Americans in such  a manner because the Constitution forbids  it.
As for the international law angle: if this is what allows the US to murder  its own citizens — just on the say so of the Office of Assassinations — then  what business has this administration in condemning Bashar  al-Assad when he cuts down his own people in the streets of Syria’s cities?  After all, the Syrians claim they are only “defending” their country against foreign  interference, including against acts of “terrorism.”  How is this different from blasting al-Awlaki to smithereens in the desert of  Yemen?
The Obamaites know they’re in the wrong, but, being self-declared “pragmatists,” i.e. utterly shameless opportunists, they put alleged necessity over principle in this and every instance.
