So ushering a fundamentalist dictatorship and taking 52 diplomatic personnel hostage is ok because it was retaliation against the three-decade-old coup, which, by the way, itself was retaliation against seizure of British Persian Oil company?
And come on Khomeini was an antiwestern fundamentalist for all his lifetime, living in France has about the same to do with it as children and families of modern Russian officials (all profoundly anti-western) living in Europe - it was likely just a better place to live, even back then. Ayatollah was always pro-Sharia and Islamic revival and other stuff like that, opposed to westernization and liberalization.
2Sergarr US were certainly not about spreading the democracy back then, though perhaps pro-liberal values, depending on what values are liberal for you. Anyway, it isn't US who's throughly mentored its people in hatred toward Iran last 40 years, it's the other way around. And yeah the world could certainly benefit from a few overthrown regimes, even some democratically elected ones, that's for sure.
EDIT: Allright, it seems to me that I've been carried of a bit and entered a discussion which seems to have no other way than "agree to disagree", as you like saying it in your civilized western pluralistic world. At the start of all it, all I was gonna say was that Iran, Cuba,(now sadly)Russia, Venezuela, Zimbabwe, North Korea or pretty much any USA-hater state hate USA only to be able to blame US for their own poverty, while in truth only their own governments' policies are responsible for that.
