Where to begin...
Source? As far as I know this was in the 1930s, and quickly revoked (and you are getting confused - this was not during the time of the Shah installed in 1953 and overthrown in 1979 - this was during the time of the previous Shah in the 1930s).
Thus, during the (latter) Shah's time, the hijab was not banned. Yet now in Iran under the clerical fascists, women are
forced to wear the hijab in public by so-called 'morality police'. They are also banned from attending male football matches. Just FYI. I could go on about the sexism of the current regime but I don't have the time, and I think you get the gist of it.
You say Westernise, I say
modernise. Alas, it is clear that the Iranian population were not ready for such modernisation. Sad.
You are at least partially correct here. But to claim that the Shah was worse than the current Ayatollahs is ridiculous and an insult to those in Iran today.
Any sources for your point about Iran's economic woes under the Shah? Iran's currency (the rial) at the time hit record highs, and Iran in the 70s were predicted to have a GDP the size of Spain's by 2000. Compare that to Iran's economy now and, well, I think you get the idea.
SAVAK were brutal and silenced internal dissent, this cannot be denied. But every state needs a strong internal security system to maintain order, especially so if they are a developing state.
As far your latter point, the Iranian people did indeed protest against the perceived corruption and brutality of the Shah, but in search of democracy, not in search of a Sharia state that was imposed upon them by the clerical fascists through violence and subversion of anti-Shah rhetoric.
True: Saddam thought that because of the general chaos in Iran immediately after the revolution he could easily invade Iran and could declare victory within weeks. I actually think this was one of the main contributing factors to why the current regime has survived for so long. The regime used the war to unite the population against the invaders, to great effect. Iran, despite being in total chaos and having imprisoned their most skilled officers etc, successfully managed to completely drive Iraq out of Western Iran by 1982 and then began a counterattack.
I disagree. Rafsanjani stopped the use of human-wave attacks in 1986, yet the US only really got involved in a major way in 1988 with the 'Tanker Wars' (where Iran laid mines in the Persian Gulf and threatened any ships passing through).
Prior to that, they didn't really take a side until 1982 when Iran launched their counterattack into Iraq and it looked like they would win. The last thing the US (or the rest of the world) wanted was an Islamist Iran to defeat Iraq, thus they supplied Iraq with weapons, protection on the international stage (see: Iraqi chemical attacks on Iran during the latter stages of the war as Iraq became desperate to prevent Iran reaching Baghdad - the US actually blamed
Iran for using the chemical weapons at first).
Read. It is worth noting that despite the chemical attacks affecting over 100,000 Iranians, the Ayatollah, for all the evil he represents, forbade the reciprocal use of chemical/biological in return (despite Iran having a large stockpile at the time).
You are incorrect in saying the US did not provide Iraq with chemical weapons.
It is ironic that many of the sanctions the US has placed on Iran forbid the exportation of 'dual-use' material, yet they were more than happy to supply such material to Iraq.
Recent CIA files also show that the US helped Saddam use chemical weapons against Iran, helping the Iraqi army with surveillance and tactics, with full knowledge that chemical weapons were to be used against Iran.
Then, to top it all off, the US shot down an Iranian civilian airliner in 1988, killing all 300 civilians on-board (
Iran Air Flight 655). They then awarded the man who ordered the shooting the Legion of Merit, and never actually apologised to Iran or recognised their culpability (though they did pay compensation to the victims after the ICJ ruled in Iran's favour).
When you look at all these incidents, and take into account how the US helped overthrow Iran's first democratically elected PM in 1953, imposing a Shah that brutally tortured his own citizens etc, can you see why Iranians might be somewhat hostile to America? I am not absolving Iran of any blame here, merely attempting to give a balanced portrayal but from Iran's eyes. Apologies for digressing, but I think it is important to understand as much as possible about the war before conclusions are made about anything.
