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).
