One of the most ambitious studies conducted on Syria’s civil war and American options to mitigate it finally saw the light of day on Tuesday.

The study, which was commissioned by the United States Holocaust Memorial Museum, had been the subject of controversy this fall after the museum briefly published it online and then retracted it in the face of a political backlash. Some groups had balked at the conclusions, which expressed pessimism about American options. Then, after the retraction, academics accused the institution of allowing political pressure to suppress important research.

The controversies appear to have blown over. In a concession to the interventionist voices objecting to the findings, the study will be republished with two additions that support the case for American military action.

Groups initially critical of the study say they are satisfied, and museum officials hope that the research can now stand on its own. But others are at least somewhat dissatisfied.
