Firstly, if you want to talk about Chutzpah or maybe hypocrisy on a grand scale, the Americans have never adhered to the NPT from the day they signed it. As far as who is the biggest rogue nation on the planet, the USA comes out miles in front of any other nation, for its deposing of elected governments, illegal covert actions in sovereign nations by the CIA and other services, its illegal wars and invasions and many more transgressions. In comparison, Iran has not invaded another nation or started a war with anybody for 2000 years. Whether you like the Iranians or not, they have legal rights that are INALIENABLE – such as the INALIENABLE RIGHT to enrich uranium. If the Americans don’t like it, then they can move to have the NPT discarded and see if a new treaty can be promulgated that FORCES all nations, including the USA, to adhere to it religiously and completely ban all nuclear weapons. Until then, under the NPT, Iran can enrich uranium to its heart’s content and nobody, not the USA, the UN, France, Germany – NOBODY has the legal right to prevent this.
