For those curious about how and where the whole "Iran thing" started: A freely elected Iranian president decided to nationalise oil fields. This irked British Petroleum (Anglo-Iranian Oil Company at the time..) and the USA, so they initiated a coup to overthow the government [1], complete with CIA-paid Iranian mobsters to push the Shah regime.
Years after this imposed rule, the western-propped government was overthrown with an.. anti-western government.
If you look at Iran with the context of 15 - 20 years history, it's impossible to understand the government's rabid anti-west stance. If you zoom out a little bit more - you understand completely.
Finally - the Iranian people suffer incredibly under this regime. The Persian culture has over 5000 years of rich (non-islamic, incidentally..) history. I'd sincerely advise traveling to Iran if you'd like to understand geo-politics a little better.
