"Iron Man originally used to be about fighting communism, now it is about fighting terrorism"

Uh? Let's look at the villains in the recent movies:

Iron Man 1: Terrorists, later revealed to be puppets of a corrupt American military contractor.

Iron Man 2: A Russian scientist with a personal grudge, later teams up with a corrupt American military contractor.

Iron Man 3: Terrorists, turn out to have been entirely made up by a corrupt American military contractor.

In every movie the real villain is a representative of the military-industrial complex. In two of the three, cutting-edge American military technology is publicly and embarrassingly subverted and used against American citizens. In the related Avengers movie, American military authorities order a nuclear attack on New York City.

There is a lot of American propoganda in American movies (oh God, Battleship), but Iron Man is a pretty poor example.

more like terrorists, which turn out to be terrorist trying to infiltrate and undermine the holy american militar complex posing as honest contractors.

Not really, no. All three were legitimately respected industrialists before getting hit with the villain stick, and are motivated only by money and power. In the one film that involves actual ideological terrorists, the villain makes them his patsies and then has them all killed to tie up loose ends.
