I'm sure there has to be some controlled opposition to ending the wars and not starting them. But if it were completing silent I imagine that might spark a reaction more than just having a loud useful idiot blabber on about it. That way there is that one guy who can control the movement. Nobody will care and think at least something is getting done about it. Whereas if it were just totally banned, it would create too much of a backlash that couldn't be quelled if it snow-balled.

TL;DR: I think Ron/Rand paul are politicians but also useful idiots. I think that without useful idiot controlling the opposition to big government and the military industrial complex, it could snow ball into major movements and public backlash.

EDIT: Sorry, the correct term is "Controlled Opposition", not "useful idiot", as that means something else. I'm a useless idiot :D For example, I'm 100% sure alex jones is controlled opposition. His goal is to make discussion of conspiracy theories look pretty crazy.
