Our new FAS Nuclear Notebook on Russian nuclear forces is now available. We estimate a stockpile of just over 4,300 warheads, modernizations, but also delays. Earlier STRATCOM projection of significant increase in tac nukes has not yet materialized. tandfonline.com/doi/epdf/10.10…




Forget the Epstein file case! We know Trump is a slime-bag and there’s no accountability in MAGA/GOP anyway. The wrecking ball nation-destroying budget is the real story. They didn’t even bother releasing the budget while twisting arms in Congress. washingtonpost.com/business/2025/…
Because the Trumpies hate facts and accountability, they try to suppress or destroy science. Other countries will fill the void and all the MAGAs will have left is their god, guns, and flags. washingtonpost.com/opinions/inter…
Definitely worth listening to! Unfortunately I won’t be able but will certainly check later. 👇👇 Under the Nuclear Shadow: A Virtual Book Talk with Dr. Fiona Cunningham | CSIS Events csis.org/events/under-n…
This is the kind of article that should not be behind paywall. 🤷🏼♂️
Read @GioeINT and Michael Hayden on how the Trump administration is making it more difficult for spy agencies to do their job well—and heightening the risk that an intelligence failure will unfold: foreignaffairs.com/united-states/…
🇨🇦 Someone over at the Royal Canadian Air Force or Canadian Armed Forces has removed one of the most useful things they had on their web site. The 2020 #RCAF map which showed the Canadian public where all the wings and squadrons were, and which aircraft were stationed there.
The US Mission to NATO appears to have degenerated into a simple propaganda outlet for the MAGA cult.
Trust in MAGA!
The Trump regime’s wrecking of the State Department was engineered primarily by a handful of political appointees lacking extensive diplomatic experience and chosen for their “fidelity” to the president and willingness to “break stuff” on his behalf. washingtonpost.com/national-secur…
The Trump regime is busy demonizing immigrants, a typical playbook of authoritarian regimes. It’s “border czar” is making false claims. @factcheckdotorg took a closer look. factcheck.org/2025/07/border…
NBC News: US intelligence assessment finds military strikes on Iranian nuclear sites destroyed only one of three attacked. Trump rejected a broader attack plan. nbcnews.com/politics/natio…
I spoke with Matthew Loh at @businessinsider.com about upgrades underway at Russian bases. Some are about modernizing existing nuclear capabilities, some about expanding or adding new, and some are not nuclear. Read more here: businessinsider.com/satellite-phot…
A headline for the ages: Dismantling the education department. nytimes.com/live/2025/07/1… One has to go to banana republics and Taliban-like religious regimes to find something similar. But educated people who base their vote on facts are dangerous to the Trump regime and GOP.

Faced with the Trump regime’s constant chaos, U.S. allies are redrawing the world’s trade map with less U.S. nytimes.com/2025/07/13/wor…
Important piece from @james_acton32 about how to develop a better nuclear deterrence posture. cfr.org/report/optimal… James’ deep thinking on these matters is desperately needed at a time when deterrence debate at times sounds more like Cold War grab-bag posturing on autopilot.
Disappointed to see this from Chatham House: removing source data from chart, referencing secondary sources, using outdated nuke data when updated is available, misrepresenting “nuclear arsenal” data. 🤷🏼♂️ Her is link to primary data source: fas.org/initiative/sta…
