An important and positive move: "Putin offers Trump a temporary nuclear arms control deal that would extend status quo by one year." ca.news.yahoo.com/putin-offe… via @@Yahoo

Time is running out. With New START expiring in February 2026, Washington and Moscow can still avoid an unconstrained nuclear arms race. The Deep Cuts Fact Sheet shows how—and the role the P5 and international community can play. deepcuts.org/publications/st…

The Deep Cuts Commission mourns the loss of Sergey Rogov, who passed away at the age of 76. Sergey was a distinguished expert on deterrence and arms control and a cherished colleague with whom discussions were always enriching. Sergey, you will be deeply missed.

This paper examines shifting geopolitical landscape and highlights increasing activities at nuclear test sites in China, Russia, and the U.S. that could indicate preparations for testing, alongside the enduring challenges posed by the CTBT's ratification process. (3/4)

To avoid this:
- The P5 should recommit to the CTBT and uphold unilateral moratoria on testing
- 🇺🇸, 🇷🇺 & 🇨🇳 should undertake unilateral and reciprocal test site transparency measures
- 🇨🇳 & 🇺🇸 should work to ratify the CTBT simultaneously with Russia re-ratifying it

Global nuclear arsenals have declined to ~13,000 warheads due to US-Russia arms control. However, other states are expanding their capacities. Future agreements need to involve more nuclear-armed states and additional systems. deepcuts.org/publications/wo…

The UNSC Permanent Five should intensify dialogue on nuclear arms issues, including strategic balance, uniform reporting, and risk reduction. If possible the exchange should be elevated to under-secretary of state level and discuss possible formats for negotiating reductions.

Unilaterally, states can conduct nuclear fail-safe reviews and share best practices among all nuclear-armed states. The US could lead by sharing its review.

So pleased to join the #10DisarmamentLACSchool where today I spoke on @iaeaorg safeguards & naval nuclear propulsion. I left the diplomats from 26 countries in the region with a reminder that safeguards are a collaborative process.

The US is set to join Russia and others in deploying hypersonic weapons – traveling at speeds over Mach 5. While alarmism is misplaced, #hypersonic boost-glide vehicles bring new risks for inadvertent escalation and arms control challenges deepcuts.org/publications/is…

To mitigate these risks, states should clarify BGV missions, maintain open hotlines between commanders who can make strategic decisions and coordinate for future arms control opportunities amongst allied states. #RiskReduction #GlobalSecurity
