Key facts

Testifies on Iran and Syria

He appeared as FDD’s executive director at a hearing of the House Foreign Affairs Subcommittee on the Middle East and North Africa. The chair introduced him as leading FDD projects on sanctions and nonproliferation and as coauthor of eight studies on economic sanctions against Iran. In his testimony he said that the “myth of moderation” revived by Hassan Rouhani’s election as Iran’s president might not be warranted and that, if that moderation proved only aspirational, Washington could allow Iran to solidify its grip on Syria and develop an irreversible nuclear capability.⁠[3]

Criticizes the Iran Nuclear Deal Before the Senate

At a Senate Banking, Housing, and Urban Affairs Committee hearing on sanctions relief under the Joint Comprehensive Plan of Action (JCPOA), he testified as executive director of FDD’s Center on Sanctions and Illicit Finance, calling the agreement “deeply flawed” and focusing his criticism on the sunset clause, which lets restrictions expire over five to fifteen years, and on what he called the “nuclear snapback.”⁠[4]

Testifies to Both Chambers of Congress on Economic Engagement with Iran

On May 12, 2016, he appeared before the House Foreign Affairs Committee, whose chairman introduced him as FDD’s executive director and the author of fifteen studies on economic sanctions. In his testimony he argued that the nuclear deal placed only limited, temporary and reversible constraints on Iran’s nuclear activities, while economic relief gave Iran hard currency that freed up funds for financing terrorism and missiles.⁠[6]

On May 24 of the same year he testified again, at a Senate Banking, Housing, and Urban Affairs Committee hearing on the role of sanctions under the Iran deal.⁠[7]

Controversy After the U.S. Withdrawal from the Iran Deal

After the United States announced its withdrawal from the Iran nuclear deal, he said he felt “ambivalent”: he agreed the deal was flawed but was disappointed that efforts to fix it had been abandoned.⁠[8]

Supporters of the deal accused him of providing the intellectual foundation for its demise; Jon B. Wolfsthal, a former Obama administration arms control official, and Barbara Slavin of the Atlantic Council both said he owned the consequences. He replied that he was being attacked by the right for being a fixer and by the left for being a nixer.⁠[8]

Placed on a Sanctions List by Iran’s Foreign Ministry

Iran’s Foreign Ministry issued a statement adding FDD and its chief executive Mark Dubowitz to its sanctions list under the country’s law on countering U.S. “violation of human rights and adventurous and terrorist activities” in the region, accusing them of “designing, imposing and intensifying the impacts of economic terrorism against Iran” and saying those on the list would face the legal consequences set out in the law.⁠[9]

Tehran said judicial action could follow against the foundation, Dubowitz and Iranian colleagues; he responded that FDD “considers its inclusion on any list put out by the regime as a badge of honor.”⁠[10]

Host Steve Inskeep asked whether he worried about a wider regional war with many casualties.⁠[14]
