Abstract
James Sebenius and Michael Singh are to be commended for advocating rigor in the analysis of international negotiations such as the one involving Iran’s nuclear program. Although they describe their offering as a neutral framework for analyzing any negotiation, they are not at all neutral regarding the negotiations with Iran; and they present conclusions that derive directly from specific substantive assumptions, especially about Iranian objectives. The authors repeatedly describe their assumptions as “mainstream,” implying that they are uncontroversial and that any differing ones are too extreme to be worth considering. For an assumption to reside within the mainstream of popular and political discourse about Iran, however, does not make it correct. Sebenius and Singh do something similar with assumptions about U.S. interests, while sliding silently between the descriptive and the prescriptive in a way that fails to contrast actual policies with possible ones that would be consistent with those interests. Many readers’ principal takeaway from their article will be that a zone of possible agreement probably did not exist as of the time of their writing and probably will not exist unless the United States takes steps toward going to war with Iran. That answer, however, given the questionable assumptions on which it is based, is very likely wrong.
