Thanks for the link,
Saucie, and welcome back.
Lotr is ultimately about ordinary people beating the evil, against all odds. That should be so clear that I wonder why they decided to show the movies if their intent is to support Ahmadinejad's regime. There's a dictator who controls the brutal hordes of orcs, but normal people, albeit weaker, unite and win. Despite the cultural differences, it's hard to imagine the people in charge hadn't realised what kind of comparisons can be drawn from that.
Of course Sauron couldn't be defeated by mere force, which, if taken as a comparison to the situation in Iran, might discourage rioting. But do they have anything that would work as the One Ring?
