"Critical Mass" - News from GLOBAL ZERO

I am pleased to share with you this first edition of Critical Mass, an exclusive new communiqué to keep you, our high-level signatories and biggest supporters, up to speed on the Global Zero movement’s many initiatives and progress.

Our small but industrious team is active on several fronts. From building Congressional support for extension of New START and a groundbreaking new plan for reductions in the US nuclear arsenal, to analyzing and intervening in nuclear flashpoints where risks of catastrophic escalation are highest, to developing a virtual reality simulation that uniquely impresses upon decision-makers the perils of hair-trigger alert and launch-on-warning, to advancing credible No-First-Use policies as “the new normal” among nuclear-armed nations – we’ve had our hands full, to say the least. I am also excited to share with you the first preview of our redeveloped Global Zero Action Plan: a politically feasible, time-bound, actionable roadmap to reach our ultimate ambition of zero nuclear weapons globally.

We are committed to regularly sharing with you throughout the year regarding Global Zero’s analysis and activities, the contributions of your fellow Global Zero leaders, as well as opportunities to join and support our critical initiatives. Mindful of busy schedules and flooded inboxes, we aim to update you every two months or when urgent developments warrant.

I hope you find this newsletter informative and useful. Please don’t hesitate to contact me directly at derek@globalzero.org or +1 202.525.9677 if you have any questions or feedback.

GZAP “2.0” – Remapping the Road to Zero

Dr. Bruce. G. Blair, Co-Founder

Achieving a world without nuclear weapons seems a more daunting challenge today than it did a decade ago. Nuclear arms control now stands on the verge of collapse as key treaties begin to unravel and the danger of blundering into a nuclear conflict in multiple flashpoints increases. 

Our new “roadmap” reflects the creative thinking of Global Zero leaders – former senior officials and high-ranking military officials – who understand the new challenges facing nuclear disarmament and still share optimism in the capacity of nations to recognize their true security interests and to seek further cuts to global nuclear stockpiles.  Continue reading....
