I haven’t seen Iron Man 2 yet (DON’T RUIN IT FOR ME IN THE COMMENTS SECTION!), but Jack Hunter’s take on it is worth a read:
In 1961, President Dwight Eisenhower warned Americans during his farewell address about the threat of the military-industrial complex. The former military man said, “In the councils of government, we must guard against the acquisition of unwarranted influence, whether sought or unsought, by the military-industrial complex.” The movie Iron Man 2 is about an America that never heeded Ike’s warning.
In the second installment of the superhero series, actor Robert Downey Jr. once again assumes the role of playboy industrialist Tony Stark, whose Iron Man suit is nothing less than a weapon of mass destruction. When he’s not getting drunk and using his contraption to shoot watermelons and dinner plates, skeet shoot-style, Iron Man is a one-man military who uses his power for genuinely benevolent reasons, albeit while enjoying an enormous ego trip along the way. When the government tries to confiscate the suit, Stark rejects their request, bragging “I have successfully privatized world peace.” The government is not pleased.
