I don't think they sounded like libertarians at all. No self-respecting Libertarian I know, little l or big L, is for snooping around behind peoples' backs, flouting the Constitution and international law, or anything like that. The Libertarians I know are for staying the hell out of other peoples' business and leaving them alone, be they individuals or soveriegn nations.

Republicans they may well have been calling themselves. They sound decidedly Fascist to me.... which, if you google on World's Smallest Political Quiz, you will learn is the polar opposite of Libertarian.
