Together with Jonas Schneider, we checked whether the NPT sky is actually falling. Our verdict: not quite. There is more good news than the current despair suggests - though we do have a few reasons for caution. Just not necessarily the same ones everyone else is worried about.

If the 553 pages of the project @smetanamichal.bsky.social and I co-led on Russia’s nuclear threats struck you as excessive, unreasonable, or hostile to human happiness, good news: Here’s the graphic version. Many thanks to the many @swp-berlin.org colleagues who made this possible!
