The Institute for Science and International Security (ISIS) and its founder, David Albright, recently released a report on the Iran nuclear agreement, formally known at the Joint Comprehensive Plan of Action (JCPOA). Over the years, the Institute has justifiably won the respect of members of Congress and nonproliferation analysts for its technical reports. This is not to suggest that the reports were without flaws. One could object to their reliance on worst-case scenarios, for example, but the scenarios themselves were analytically rigorous. Sadly, this most recent report relies on speculation more than technical analysis or evidence based claims.
