The problem with this issue is that Julian Assange cannot be considered a traitor if he is not an US citizen.

Yeah, this. I read an opinion piece yesterday by the horrible Michael Reagan shrieking Assange should be charged with treason and then hanged. Two blood vessels in my forehead burst. "He's not American!" I screamed. I screamed it so hard I ruptured a disk in my neck. Now I can't turn my head and my left arm is drawn into a claw.
