OTD in 1963, JFK delivered his iconic American University speech—arguably the greatest address on nuclear weapons by a US president. Writing for @thebulletin.org, Matthew Bunn (@matthew-bunn.bsky.social) argues its lessons on unilateral restraint are urgently needed for President Trump today. 🧵👇

President Macron's new concept of 'dissuasion avancée' marks a revolution in French nuclear policy. With this, Paris seeks to complement—not replace—US extended deterrence.
This article is part of The AI Power Trip, a year-long Bulletin special project examining how the people and organizations developing artificial intelligence applications are gaining control of the world’s governance, information ecosystems, energy resources, military-industrial complex, and more.
"An honest look at where the industry stands with regard to achieving artificial general intelligence—however that’s defined—shows a vast and perhaps permanent gulf between machine and human intelligence," writes Sara Goudarzi @saragoud.bsky.social.
