Shame on who?

Fool me once, shame on you; fool me twice, shame on me.

Iran has been engaged in efforts to acquire the capability to build nuclear weapons for more than two decades. Tehran has developed a range of technologies, including uranium enrichment, warhead design, and delivery systems, that would give it an option to obtain nuclear bomb in a relatively short time frame. The Iranian regime's nuclear weapons program remained secret until 2002 when the National Council of Resistance of Iran held a press conference revealing a uranium enrichment facility at Natanz and a Heavy Water plant at Arak.

Tehran claims that its nuclear activities are entirelypeaceful, and that international concern about it seeking a nuclear bomb is misplaced.

Iran and the P5+1 group -- Britain, China, France, Russia, the United States plus Germany -- have been engaged for nearly two years in negotiations on Tehran’s nuclear drive. The deal is aimed at preventing Iran from developing the atomic bomb in exchange for an easing of crippling economic sanctions.

The two sides signed a framework agreement on April 2 and began meeting in Vienna on Wednesday to start finalizing a deal which is due by June 30.

However, differences have emerged over the interpretation of the protocol and the issue is far from resolved. The Iranian supreme leader, Ali Khamenei, who has the final word for Iran on the nuclear negotiations, insisted publicly that the sanctions must cease on the day a final agreement is signed, while Americans have said the sanctions would be lifted in stages afterward, to ensure that Iran keeps its promises.

Khamenei also threw a new complication into the talks on May 20 when he rejected what he called arrogant demands for access to all Iranian nuclear sites.

Khamenei told military commanders in Tehran, “The impudent and brazen enemy expects that we allow them talk to our scientists and researchers about a fundamental local achievement, but no such permission will be allowed.” His remarks broadcasted on state television were basically meant for public consumption, and maybe he has privately signaled more flexibility over the inspection issue.

Mr. Fabius clearly rejected the Khamenei’s public assertion, saying on Wednesday that France would reject a deal “if it is not clear that inspections can be done at all Iranian installations, including military sites.”

Amano, head of IAEA, also said that once there is a deal, 'several months will be needed' to investigate whether there were any military dimensions to Iran’s research. If Iran signs a nuclear deal with world powers it will have to accept inspections of its military sites, Amano told AFP in an interview.

As the talks reconvened, Khamenei seemed to be dealing with conflict at home over the nuclear negotiations. Khamenei praised the work of the negotiators, led by Foreign Minister Zarif, and told lawmakers Mr. Zarif’s team is “making genuine efforts to settle the issues” in the talks. Khamenei’s remarks came a few days after a secretly made cellphone video viewed on the Internet depicting a hostile exchange in Parliament between Zarif and a conservative lawmaker, Kouchakzadeh, who accused Zarif of treason for making concessions in the nuclear talks.

The negotiators have also signaled possibility of June 30 deadline extension as France’s ambassador to the United States, said on Tuesday, that he thought that there would not be any agreement before the end of June or even after June.” Iranian negotiator, Abbas Araghchi, said on Wednesday that talks would continue until the deadline and could continue beyond that. Soon after, State Department spokesman Jeff Rathke said at a news briefing, "We're not contemplating any extension beyond June 30."

The history of making concessions of Obama and the West in nuclear talks to Iranian regime, make us to be deeply pessimistic about the outcome of possible nuclear deal. Iran has continuously fool around the West by extending to achieve final nuclear deal from a deadline to another. Fool me once, shame on you; fool me twice, shame on me.
