You're either a liar or a fool. I suspect both. You supposedly read the 159 page text, yet you continue to peddle absurd and patently false observations - the same peddled by the histrionic critics of the deal. Case in point, your complete ignorance of the Treaty on the Non-Proliferation of Nuclear Weapons, which is referenced to early and often in the JCPOA. You wrote that Iran would be able to legally pursue nuclear weapons after the sunset of the deal, a notion which is ludicrous to anyone with a rudimentary understanding of the subject. That was not a one time gaffe; you've made numerous such errors in discussions of Iran's nuclear program.
The Iranians are not being given verification and monitoring privileges. The IAEA must account for past possible military dimensions (PMD) of Iran's nuclear program before the agreement can be implemented. The environmental samples being taken at Parchin, a sensitive military facility, are being collected by Iranian personnel under IAEA supervision. That isn't unreasonable. Americans would have balked if Soviet inspectors were able to go anywhere they pleased on American military bases to verify that the US was adhering to its obligations under SALT I. Iran's concerns are understandable given that the primary logic of Iran's nuclear program was to establish deference vis-a-vis the United States.
More limp dick reasoning. If Iran withdraws from the agreement, the remaining parties will no longer be bound by the terms of the deal. Sanctions can and will be reimplemented with a vengeance. The efficacy and legitimacy of a preventative strike against Iran's nuclear program will be significantly increased by the deal. In the event of an Iranian withdrawal, military action is much more likely.
