Iran is not breaking any international law. There is no international law against building nukes. There is only an agreement that countries will get cheap uranium if they don't build nukes. But taking part of this agreement is voluntary.

Don't let the media trick you into believing they are doing anything illegal.

IMO, Iran is building the nukes out of self defense. They are just so tired of having to listen to the US's crap and being the US's bitch. They want the bomb so they can say. "Get the fuck out of here!!!"
