From late 1951 to August 1952, Rostow headed the Soviet Vulnerabilities Project. The project, which was sponsored by the CIS and received significant support from the U.S. government, sought to identify Soviet vulnerabilities with regard to political/psychological warfare, and it received contributions from top Sovietologist and psychological warfare specialists. In June 1955, Rostow headed a group of stalwart cold warriors who were called the "Quantico Vulnerabilities Panel" which issued a report that advocated nuclear coercion of the Soviet Union. Although the experts were invited by Nelson Rockefeller, their proposal ran contrary to the policy of the Eisenhower administration.
