They really shouldn't have to agree to this; but if this is what it will take to get the Zionists off their backs, they are wise to agree.
All of Iran's stockpile of uranium that has been enriched to 20 percent, a short hop to weapons-grade fuel, would be diluted or converted into oxide so that it could not be readily used for military purposes.
No new centrifuges, neither old models nor newer more efficient ones, could be installed. Centrifuges that have been installed but which are not currently operating — Iran has more than 8,000 such centrifuges — could not be started up. No new enrichment facilities could be established.
They may always work out later deals to replace aging centrifuges. If they have enough up-and-running centrifuges to give them all the nuclear fuel they think they will need, they should be satisfied but not agree that they were acting outside the international law but were adhering to the Nuclear Non-Proliferation Treaty to the best of their ability: Good faith.
Agree with thine adversary quickly, whiles thou art in the way with him; lest at any time the adversary deliver thee to the judge, and the judge deliver thee to the officer, and thou be cast into prison. (Matthew 5:25)
Of course, that's speaking about God allowing you to be handled by Satan for cause.
We think it would be extremely wise for Iran to focus on alternative energy: clean and safe energy rather than the current nuclear and carbon.
This deal needed to get done though. Now the challenge will be for the powers to not allow the Zionists to poison the well. Take heed. Watch out for dirty tricks and lies.
Now, if John Kerry can preside over a final, reasonably fair deal with Iran and also a real deal between the Palestinians and Zionists (backing off the Zionists' ethnically bigoted land grabbing, etc.) and end the bloodshed in Syria without installing al Qaeda as the government there, he will have gone a long way in redeeming himself (and somewhat the US by extension). He will also show just how unproductive Hillary Clinton was: very unproductive.
