Scary stuff in troubling times. I can appreciate not wanting public trials for terrorists; the proceedings against those involved in the 1993 bombing of the WTC allowed anti-terror tactics of the government to be made public, and they also allowed the terrorists to abuse due process. It's the broad definition of "terrorist" in this executive order, and the broad powers to convict and condemn, without the declaration of war by Congress that's bothering me greatly.

Perhaps someone could explain the process of issuing an executive order. Does it need to have Congressional approval; can Congress strike it down; does it override the legislative and judicial branches of government? Can a President simply give an executive order and "make it so"?
