Once again Copperline you leave me stunned !! The West supported the Shah of Iran , now Iran is ruled by a bunch of Theocrats that deprive their people , as ALL MUSLIM nations do , of their fundamental liberties , one of them the choice of faith .
Exactly Militiades The Pahlavi regime was, by any stretch of the imagination, anti-democratic and authoritarian if not to say brutal (and supported by the west as you say. In Iran during the 1960s and 1970s there was a strong and growing democratic and socialist and trade union movements which the Shah's apparatus of internal repression slaughtered. Having annihilated the internal democratic and secular opposition - with the active assistance of the USA and UK, the last flickering lights of which contributed to the 1979 revolution, all that remained in effective opposition was ... (from safe in exile in France) Khomeini's forces of reaction and Islamic fundamentalism.
Something very similar nearly happened in Turkey - military coup followed by brutal repression and sustained attack on democratic and socialist movements, followed by the rise of Islamist political movements - all with the connivance and active support of the west.
