I mean, when everyone had to take the anthrax vaccine, that didn't piss people off. I would think BEING LIED TO ABOUT IRAQ would be a much bigger concern. Since a soldier gives up their bodily autonomy to the government, being forced to take untested vaxxes is nothing new at all. Being directly lied to by your commander in chief and the rest of his administration about the very reason behind your operation - that's a hell of a lot worse.
