I just noticed this thread and, I usually just read here at SWJ, but I can't help myself.

Dude, respectfully, you totally missed the point of Iron Man 2 if you think its pro-privatization of defense.

The whole point of the film is that the US can't rely on Tony Stark (who himself symbolizes private industry) because, despite being a heroic genius, he's also overworked, an alcoholic, and arrogant to the point of miscalculation. The point of the War Machine character--and the conflict between him and Stark--is that allowing the military to fall too far behind private individuals in terms of firepower is dangerous to the nation. The film's conflict is resolved and its villains defeated--in true American fashion--with a partnership between private innovation (Stark) and government/military teamwork (Rhodes, Fury, Widow, SHIELD, etc).

Stark oversells himself (again a jab at privatization) to Congress by saying he's years ahead of any competition, only to be proven wrong when Whiplash (another private contractor, by the way) attacks him at the race.

Most importantly, did you not see the scene were Stark is drunk in the suit, stumbling around using the the most powerful weapon in the world for a self-indulgent bender? You think thats not a metaphor for private industry responsibility?
