The reason this has the whiff of a Lyndon LaRouche conspiracy is that this is a private organizations that first wants you to donate money while fraudulently masquerading as some sort of public task force, even though its own documentation demonstrates that it is nothing of the sort.
It is a serious subject, but this Dr. Pry has no published credentials indicating expertise in the area, expertise that is maintained in a few places in the U.S. Government, e.g. Defense Threat Reduction Agency, AFRL, NRL, Sandia National Lab, Lawrence Livermore Lab and Los Alamos National Lab. As near as I can tell, he is associated with none of these organizations.
Dr. Pry served on the staffs of the Congressional Commission on the Strategic Posture of the United States (2008-2009); the Commission on the New Strategic Posture of the United States (2006-2008); and the Commission to Assess the Threat to the United States from Electromagnetic Pulse (EMP) Attack (2001-2008). Dr. Pry served as Professional Staff on the House Armed Services Committee (HASC) of the U.S. Congress, with portfolios in nuclear strategy, WMD, Russia, China, NATO, the Middle East, Intelligence, and Terrorism (1995-2001). Dr. Pry was an Intelligence Officer with the Central Intelligence Agency responsible for analyzing Soviet and Russian nuclear strategy, operational plans, military doctrine, threat perceptions, and developing U.S. paradigms for strategic warning (1985-1995). He also served as a Verification Analyst at the U.S. Arms Control and Disarmament Agency responsible for assessing Soviet compliance with strategic and military arms control treaties (1984-1985).
In other words, this guy is a professional staffer and policy analyst, not an experienced scientist or engineer with expertise related to nuclear weapons.
For instance while he claims he served on the Commission on the New Strategic Posture of the United States (2006-2008). But one can see from the commission report that Peter Pry served as one of a long list of "assistants to the commissioners."
