Well the point is that Iran was transparent regarding its nuclear ambitions(of course that could deviate from civilian to military use at any given point of time) however the west and the media would not have you believe that. They portray it as though they miraculously stumbled upon a discovery on big bad Iran. Perhaps to prepare their domestic audience for yet another war. Conducted by the Nobel peace prize recipient.
In regards to your point, I dont think the west would tolerate such a thing. It would drastically shift the balance of power in regards to mideast geopolitical arena. Then there is the threat that Iran may leak the technology to its cronies. I just dont see Israel standing for it. We know what it did in Iraq and I assume they would at some point do the same in Iran. However this time they will or they are getting the USA to do its dirty deed.
Thats just IMO as I see it.
