I agree with Warped9, TREK_GOD_1 and Roddenberry (through Kirk) here. The words of the U.S. Constitution are ultimately meaningless if they don't apply to everyone, friend and enemy alike. The document would likely be the greatest ever created in the history of man if we treated people the way it says we should.
One's a Canadian and the other is a God stuck on the edge of the galaxy. Not exactly guys I want to take American Civics lessons from!!
I don't even think we can say, "Maybe at some point the Supreme Court ruled the Constitution applies to all people the soldiers and government of the US interacts with." Hasn't WW3 happened by now?
