It's not Anarchy, yet it's not communism, yet it's not a Republic either. I'm not sure what you call Iran. It has school-like rules regulated like FEDERAL law.(Such as strict dress code). So in that way, I guess it's leaning communistic.
Edit: Here is Iran's chart.
Important things to note:
Venus-Neptune Conjunction in 9th house Saggitarius. Neptune is the planet of illusions, visions, etc. Also of faith and religion. To see her here in the 9th house is fitting for Iran. But Saggitarius(Ruler:Jupiter) is not. However, the placement is fitting Neptune(Religion, Vision) onto Venus(Ruler of looks and women).
Further tieing into that, is Saturn inside the Sixth House of Public Work(and ruler of the MH and Aquarius Sun) is opposite Venus-Neptune conjunction. So there is a strong perception against the looks of a woman.
Moon-Jupiter-Mercury Bi-Sextile:
Mercury(Higher plane/thoughts)-Moon(Emotions/also Women)-Jupiter(Expansion).
This could be, after the US Installed Shah in 1954, the People's Emotions expanding to a high enough philosophy to create the Republic. I can't see it any other way. Giving Mercury in 11th, Moon in 1st, and Jupiter in 5th.
It could also be that Iran is very accepting of other religions/peoiple(Jupiter/Mercury in the 5th/1th axis).
If Iran is indeed supporting Hamas, it is likely an activation of Iran's Sun/Mars conjunction in the 11th house of social friendships. Not even the treehugging US to Israel has such a conjunction.
Incidentially, Jupiter also opposes this conjunction in 11th. I can read this as saying that the action is determinal to the growth of the Republic.
Pluto-Trine Neptune: The 7th house in Mudane Astrology may very well be the House of War. If that is the case, then Pluto(Power) is recieving energies from Neptune's vision(In the 9th house of foreign arries). As they say in Iran. "Death to America".
NOTE: In Iran "Death" is to "dang" in America, if our Press were to ever report that, the hatred of Iran would seize entirely

.
Pluto-Trine Sun: In conclusion, I think I understand Iran alot better by reading his chart. The Sun is the personality, the soul so to speak of the person. Inside the 11th house of friendship trining the 7th house of war. Iran's Prime Minister has said he seeks a democracy inside of Israel. See my revealing Israel's non-democratic ways in her chart.
I think that the names "Iran", "Iraq" and "Israel" are interesting to me. It wouldn't surprise me, if infact astrologically these countries have some kind of sibling ties. And if so, could Iran be the bigger brother trying to help it's fellow countries? The 11th house stellium and Sun suggests this possibility.
