Petro-euro, the Iranian Bourse and the US of A

Well I have been doing some interesting (although one sided) reading.

First I read this and then this. Followed by a short rebuttal here. Again I read an article in favour of the prior position here.

It is an interesting subject that I was totally unaware of and I am looking further into it.

Anyone know any good (and by that I mean relatively unbiased, as all what I have read so far os biased one way or the other...) sources
So, is there any truth here?
