According to Gary Samore, Iran’s nuclear enrichment program has had some important recent setbacks. The AP, last week:

Setbacks in Iran’s uranium enrichment program have significantly delayed its progress toward building a nuclear weapon, President Barack Obama’s top nuclear adviser said Tuesday.

…On Iran’s enrichment program, Samore said that Tehran had been set back by problems with its centrifuges and by disclosure of an enrichment plant near Qom that the United States alleges was part of a secret nuclear program.

Samore said that because of the setbacks, “the nuclear clock is not ticking as quickly as some had feared.”

Samore’s lengthy title is “Special Assistant to the President and White House Coordinator for Arms Control and Weapons of Mass Destruction, Proliferation, and Terrorism.” So he should know, right?

Samore seems to be saying that this threat is not yet technologically imminent. The statement is not quite as precise as the 2005 NIE, which reportedly said that Iran’s nuclear bomb was at least a decade away, but it’s still good news.

The comments seem to be directed at Iran hawks, of course, and also at the policy wonks who have recently been upset by Iran developments. For example, in a February blog post, my go-to source for proliferation information Dr. Jeffrey Lewis, emphasized the very bad news in Iran’s just-announced plans to enrich uranium to 20%.

If Iran enriches a significant amount of U235 to 20 percent — and that’s a stated goal right now, not yet an actual achievement — then Iran would be able to “top off” the enrichment [at] a small, clandestine facility like the one revealed near Qom.

In a comment to the Lewis post, Yale Simkin simplified the problem for those of us without a lot of nuclear physics:

Imagine a bowl with 1,000 ping-pong balls in it. 993 of the balls are green. 7 of the balls are red. The balls are at “0.7% Red Enrichment.”

Now imagine reaching in the bowl and pulling out unwanted green balls. You are doing “separative work”. You will be leaving the red balls in the bowl.

Remove 840 green balls, a long and tedious job. Now you have 153 green balls and 7 red balls.

You are now at “4.4% Red Enrichment”

Last step. This time remove only 152 green balls.

This leaves 7 red balls and 1 green ball or an “88% Red Enrichment.”

So note: It took EIGHT-FIVE percent of the work to go from 0.7% to 4.4%!

That is why “Peaceful” enrichment is a fraud…

What other wonks have been worried about Iran policy?

Back in February, the Leveretts argued that the Obama administration was dithering recklessly in the ongoing negotiations:

…the Obama Administration and its European partners have effectively rejected these Iranian positions—precisely because accepting them would mean that the Obama Administration would not have a year or more to sort through what it is prepared to do regarding the prospective substance of U.S.-Iranian engagement. Instead, the Administration would have to make strategic choices and develop real positions on important issues much sooner than it had contemplated. And, rather than do that, the Obama Administration is moving to embrace the same counterproductive and feckless policies aimed at isolating and pressing Tehran that the George W. Bush Administration employed.

I too have expressed fears that the Obama policy looks too much like the Bush Doctrine in the right light.

Sixteen months into this administration, the U.S. should clearly work “faster, please” to achieve results in the Iran negotiations. Election-year promises about bargaining without preconditions are beginning to fade from memory even as blustering threats are occasionally made public. The so-called “Zombie fuel swap” proposal may not be a sufficient solution.

In any event, this latest news is perhaps a sign that the world has more time to work out a reasonable compromise.
