I wish to be very precise here on this extremely important matter. President Trump has not “decertified” the JCPOA Iran nuclear deal. Now Congress must ultimately be responsible. He has, after a lot of discussion and intervention by his national security team, failed to certify the deal. This is not something that was part of the deal, but an epiphenomenon put in place by the US Congrees as part of a deal agreed to by former President Obama to get the deal through, a matter of every 90 days the US president certifying that Iran is complying with the agreement. Two times running, President Trump certified it, confronted by the hard fact that Iran has been complying with the deal according to every official body in the world. But, he has said he would not certify it, and reportedly he has blown up over this matter with screaming fits his c. So his NatSec team has cooked up this partial save: OK, boy, fail to certify, putting it on Congress to really undo the deal.
In the face of way more to say than I shall here, let me point out odd items most will not. So one of those is a positive. Even if the Congress fails to do what is right and reasonable and keeps the deal going, probably Iran will not pursue an active nuclear weapons acquisition program. There are two reasons for this, which could easily be undone if Trump continues to insanely go after them.
The first is that this whole negotiation with Iran was an unnecessary farce to begin with. Vilayet-al-faqih Ayatollah Ali Khamenei was issuing fatwas against the building of nuclear weapons as far back as the G.W. Bush admin. Pres Bush even accepted two official National Intelligence Estimates (NIEs) that declared that Iran was not actively pursuing a nuclear weapons program. He did it twice. The fatwas by Khomeini were the ultimate reason why these hard fought and deeply studied NIEs came forth, representing after all a consensus of every one of 17 plus US intelligence agencies, who have a wide variety of perspectives, some of them almost insanely hawkish. But twice during the G.W. Bush presidency they came together to make this super official certification: Iran did not have an active nuclear weapons program, even though it had one earlier, one that dated back to the Eisenhower admin when the US supported their program under the Shah. But, the bottom line is that while Khamenei is alive, there will be no Iranian nuclear program.
