Iranian Elections

It appears that the election in Iran was rigged.

I don't feel like I understand what's going on in Iran as well as I should. Comments? One thing I haven't seen at all and am interested in is how what's happening right now in Iran might relate to the war in Iraq - if it is related to any significant extent - that's part of what I want to understand. How what's happening now relates to our policy toward Iran in recent years is also of interest.

[And since this is an economics blog, predictions and explanations about how this might affect the world economy - oil markets for example - are also welcome, though I am not expecting much effect, at least not at this point.]
