Freeze proposals have come in many variants and have had varying degrees of political support across a wide spectrum. Yet many questions of practicality remain, the chief ones involving feasibility and the connection with more traditional forms of arms control. The hearings format adopted by the Federation of American Scientists was a superb way to dig into particular questions and problems as well as to elicit general statements about these complicated issues. Randall Forsberg (initiator of the freeze movement), Richard L. Garwin, Paul C. Warnke and Robert W. Dean (of the State Department) testified; they were questioned by knowledgeable experts. The result is the best and most informative analysis to date of the freeze concept.
