David Albright and Andrea Stricker
      The conflict over Iran’s nuclear program appears to be getting worse.  In June, Iran decided  to relocate 20 percent enrichment at its fortified Fordow enrichment  plant near Qom and install advanced centrifuges that would triple its  enrichment output.  These steps will make it easier for Iran to quickly  break out to nuclear weapons.  As British Foreign Secretary William  Hague pointed out in a recent Guardian op-ed,  moving enrichment to Fordow and tripling output makes little sense in  terms of its civilian nuclear program, which Iran claims is the only  purpose of its nuclear program. 
       Iran’s  appointment of Fereydoun Abbasi-Davani as the head of the Atomic Energy  Organization of Iran (AEOI) has increased the crisis atmosphere.  Abbasi-Davani is a physicist widely suspected of having background  in Iran’s nuclear weapon research programs.  He has regularly been  linked to Iran’s efforts to actually craft a nuclear weapon, a process  called weaponization.  Abbasi-Davani was a key scientist in the Iranian  covert nuclear weapons program headed by Mohsen Fakhrizadeh, a strong  supporter of Iran’s nuclear weapons program, according to an expert  close to the International Atomic Energy Agency (IAEA). 
       Abbasi-Davani  personally directed work to calculate the yield of a nuclear weapon; he  also worked on high energy neutron sources, the expert said.  Iran’s  continued work on nuclear capable ballistic missiles and failure to announce these launches adds further to this growing list of suspicions.
        Iran’s  decision to move 20 percent enrichment to Fordow could be aimed at  acclimatizing the international community to conditions that would make a  breakout to nuclear weapons more feasible.  By increasing the  enrichment level and its stock of 20 percent low-enriched uranium, Iran  could reach a so-called “break out” capability that would enable it to  make enough weapon-grade uranium for a nuclear weapon in a few months.   Iran already has the knowledge to build a crude nuclear weapon,  according to the IAEA. 
        Iran  is likely to continue to expand its enrichment capability until it  needs less time to make the requisite amount of weapon-grade uranium for  one explosive device.  Once Iran reaches a certain capability, it could  decide to take that step to make nuclear weapons.  Having a device  sufficient for testing may be all Iran wants.  North Korea settled for  that scenario, while it improved its ability to make deliverable nuclear  weapons.
        Enrichment  at Fordow also offers Iran the benefit of protection from air strikes,  since the facility is located 90 meters underneath a mountain.  If Iran  were to restrict IAEA inspectors from having access to the plant, little  could be done aside from bombing the facility’s tunnel entrances or  introducing ground troops, which could trigger a full-scale war. 
In the absence of a negotiated settlement, Iran appears to be steadily moving to a status as a virtual nuclear weapons state in which it could build nuclear weapons quickly and easily. Once it reaches this capability, what will the Iranian regime decide? Will the temptation be too great to resist? In order to bridge the gulf and prevent Iran’s slow slide to nuclear weapons, the most viable option for the international community is an intensified dual track approach of both pressure and negotiations.
