Yes, there was some secret fine print that allowed President Obama to lie to the American people about the strength of the deal.

Details published earlier outline most restraints on Iran’s nuclear program meant to reduce the threat that Tehran will turn nuclear activities it says are peaceful to making weapons.

But although some of the constraints extend for 15 years, documents in the public domain are short on details of what happens with Iran’s most proliferation-prone nuclear activity – its uranium enrichment – beyond the first 10 years of the agreement.

The document obtained by the AP fills in the gap. It says that as of January 2027 – 11 years after the deal was implemented – Iran will start replacing its mainstay centrifuges with thousands of advanced machines.

Centrifuges churn out uranium to levels that can range from use as reactor fuel and for medical and research purposes to much higher levels for the core of a nuclear warhead. From year 11 to 13, says the document, Iran will install centrifuges up to five times as efficient as the 5,060 machines it is now restricted to using.

Those new models will number less than those being used now, ranging between 2,500 and 3,500, depending on their efficiency, according to the document. But because they are more effective, they will allow Iran to enrich at more than twice the rate it is doing now.

Components other than centrifuge numbers and efficiency also go into the mix of how quickly a nation can make a nuclear weapon. They include how much enriched uranium it has to work with, and restrictions on Iran’s stockpile extend until the end of the deal, crimping its full enrichment program.

But a comparison of outputs between the old and newer machines shows the newer ones work at double the enrichment rate. That means they would reduce the time Iran could make enough weapons grade uranium to six months or less from present estimates of one year.

And that time frame could shrink even more. While the document doesn’t say what happens with centrifuge numbers and types past year 13, U.S. Energy Secretary Ernest Moniz told The AP that Iran will be free to install any number of advanced centrifuges beyond that point, even though the nuclear deal extends two additional years..

Remember these heady assurances?

Whereas Iran was steadily expanding its nuclear program, we have now cut off every single path that Iran could have used to build a bomb.  Whereas it would have taken Iran two to three months to break out with enough material to rush to a bomb, we’ve now extended that breakout time to a year

Except there will be a path to a bomb and the breakout time will be much less than a year. But other than that…
