Why did Margaret Thatcher oppose German reunification 35 years ago? Yes, she disliked the Germans - but her deeper fear was socialism creeping into Britain through the Brussels backdoor, driven by an increasingly dominant Germany. Probably my best research. Let me know if you’d like a copy.

Comprehensive sanctions create a siege mentality that worsens efforts to prevent nuclear proliferation, while targeted sanctions avoid harm to entire populations & offer credible off-ramps & de-escalation pathways to better support non-proliferation, argues Sergey Shkolnikov @thebulletin.org 9/10
How to design nuclear sanctions that don’t backfire
International sanctions can have a paradoxical effect, spurring some nations to push harder to obtain nuclear weapons. Here’s how sanctions can be more effective.

Europeans should welcome Putin’s New START extension offer and play an active role in shaping a future arms control deal—one that reflects Europe’s interests by resuming data exchange, addressing short- & intermediate-range missiles, argues @olivermeier.bsky.social @theeln.bsky.social 6/10

Putin’s extension offer comes at a critical time for a Russia facing overstretched resources & nuclear modernization challenges - but the US should weigh this offer carefully, considering past Russian arms control behavior & China’s efforts, argues @pranayrvaddi.bsky.social @rusi.bsky.social 5/10
Beware Russia Bearing Arms Control Gifts
Washington should maintain a critical eye when measuring Putin’s latest arms control offer.

The government shutdown puts the US Department of Energy—which oversees the US nuclear arsenal and international non-proliferation—at risk, potentially forcing it (once again this year) to cut workers already in a week, reports @politico.com 3/10
Money to oversee nuclear weapons safety will start running low after 8 days, Energy secretary says
The National Nuclear Security Administration will need to ramp back its work, which ranges from maintaining the weapons arsenal to international non-proliferation efforts.

The Trump administration should seize Putin’s offer to cap nukes, push for on-site inspections & data exchanges & use the time to explore ways with Russia & China to cut nuclear risks - from political commitments to executive agreements, argues @matthew-bunn.bsky.social @thebulletin.org 6/10
Putin just gave Trump the opportunity to maintain nuclear restraint. Will he seize it?
Extending New START will also give time for Trump to work with Russia and China on future arms control accords.
