As Prime Minister Binyamin Netanyahu pulls main political groups into a wall-to-wall coalition, he is in position to choose either military attacks on Iranian nuclear sites or to wait for international sanctions and covert action to compel Tehran to cease progress on a nuclear weapons capability. At issue, however, is whether these are the only alternatives available.A third option involves regime change from within Iran, of the kind to make less likely pursuit of nuclear weapons capability. Such an approach requires Jerusalem and Washington to have friends in Tehran.The writer was a frequent Visiting Professor at the Hebrew University of Jerusalem, is Emeritus Professor at the University of Michigan, and former member of the Senior Staff of the National Security Council in the Reagan- Bush administration.While the enemy of my enemy might still be my enemy, assume for the moment the conventional wisdom is correct: An enemy of the Iranian regime is a good candidate to be a friend of Israel.In fact, the main Iranian dissident group that rejects clerical rule in Tehran, the Mujahedeen-e-Khalq (MeK), reaches out to Washington and does not oppose Israel.By contrast, the Iranian Green Movement faction, headed by Mir Hossein Mousavi, accepts clerical rule and has a history of anti- Israel activities, such as calling for it to be annihilated.As the US State Department decides whether to remove the MeK from its terrorist list, the drive to be delisted would benefit from a push from the pro-Israel community.Because delisting would send an implicit but unmistakable signal to Tehran that regime change from within is on the table, one would think the pro-Israel American community would be active in the fight for removal of the MeK from the list. But there is no sign of the community’s influence in the delisting process. The community, however, is very active in the sanctions process.As sanctions pressure Iran to make concessions at the May 23 Baghdad talks on Iran’s nuclear file, it is useful to note that Mousavi of the Iranian Green Movement said consequences of giving up Iran’s nuclear program would be “irreparable.”In contrast, the MeK opposes Iranian production of nuclear weapons; and to back up its words, the MeK reveals Tehran’s covert activities to procure uranium enrichment and weaponization materials. In issuing blockbuster intelligence on Iranian progress toward nuclear weapons capability, moreover, the MeK laid the framework for international sanctions imposed on Iran.There is an assumption among pundits of an alliance of convenience between Israel and the MeK, but it rests on thin evidence of unnamed officials and an Iranian intelligence agent.Allegations of a covert alignment works in favor of those who would keep the MeK on the US terrorist list, weakening its ability to help build a coalition to remove the clerical regime from power in Tehran. While uncertainty about such an alignment may reinforce Israel’s deterrent posture vis a vis Iran, it may be only a Pyrrhic achievement in view of costs incurred in inadvertently maintaining the MeK on the US terrorist list.In a research trip to Iraq during 2008, I reported on interviews and documents that corroborated a tight relationship between the MeK and the US military in Iraq, but not with American diplomats. In addition, I leaned how Iran’s Ministry of Intelligence and Security (MOIS) spreads false narratives about the MeK, some of which US diplomats echo.In October 2011, MeK-supplied information reinforced US intelligence to expose Iran’s Islamic Revolutionary Guards Corps-Quds Force for plotting to assassinate the Saudi Ambassador to the United States and blow up the Saudi Embassy in Washington.That disclosure reinforced additional sanctions the US Treasury placed on the IRGC-QF three days earlier.And what is Tehran’s response when confronted with evidence of its complicity in the assassination plot? The Ministry of Intelligence and Security blamed Israel and the United States, while also claiming MeK involvement.To its credit, the State Department promptly denied MeK responsibility, accused Tehran of “fabricating news stories,” and of spreading “disinformation” to exploit skepticism about the plot.While it might make some strategic sense for Israel to remain silent about any involvement with the MeK and sit on the sidelines in the group’s effort to be removed from the US terrorist list, there is no excuse for the pro-Israel community to refrain from seeking removal of the MeK from the list and helping to allay suffering of its supporters in Iraq, who languish under prison-like conditions, hoping to be resettled in friendly countries rather than forcibly repatriated to Iran.The State Department has said it was looking favorably at delisting the MeK if it continued cooperating by vacating a former base inside Iraq, called Camp Ashraf, to another location, Camp Liberty.There are about 1,200 MeK members remaining in Ashraf and some 2,000 already in Liberty.But the fly in the ointment is that State Department also said it might still rule against de-listing the MeK if evidence turned up of a capability and intent to commit terrorism after complete relocation to Liberty.Such a condition is a virtual invitation for Iranian agents to plant weapons in Ashraf, which then could be used by State Department as indicators of capability and intent for the MeK to commit terrorism.It is in this final phase of decision making at the State Department where the American pro-Israel community might make a difference, but it sits quietly on the sidelines of an epic struggle over whether US policy should include a “regime change from within” option for Iran.
