Nuclear Weapons

PSR Arizona Advocates for Elimination of Nuclear Weapons

PSR AZ participated in the National effort to support the New START Treaty. We worked throughout 2009 and 2010 on the CTBT and New START with a national coalition with PSR, Friends Committe on National Legislation and the Arms Control Association. In the Fall of 2010, we were awarded a grant from the Ploughshares Fund to further the treaty process and hosted a film, a workshop on the New Start Treaty and collected and delivered 1600 postcards to each of our senators to encourage their vote for the New START. We will continue this work for the CTBT (Comprehensive Nuclear Test Ban Treaty).

A History of the Nuclear Age

"You Might Want to Know"

By John P. Warnock

PSR Arizona is pleased to announce that award-winning author and English professor emeritus at the University of Arizona, John P. Warnock, will be sharing his amazing collection of writings on the history of the atomic and nuclear arms race with us in a twice-monthly column.

He calls his work “literary nonfiction of a new kind that combines memoir with actual history” of the nuclear era and its impact on the planet and our lives. We call it a fascinating collection of accessibly written knowledge, and a must-read for anyone concerned about the threat of annihilation that nuclear weapons pose.
