Julia Gray's review of my book, Enemies in Agreement, for The Review of International Organizations is thoughtful, rigorous, and full of ideas for reading arms control through the lens of IO literature. link.springer.com/epdf/10.1007...

Arms control in a post-Trump admin world would be very much a work in progress, says Jane Vaynman @janevaynman.bsky.social. "The goal now is to do the thinking—about what arms control should look like, and for what threats—so that when conditions do shift, we’re positioned to act on them."

The @statedeptus.bsky.social 2021 "compliance report" is the most detailed unclassified statement on Russian, Chinese nuclear testing. DIA said something similar in 2019. Russia is directly accused of low-yield testing, while there are only concerns about Chinese transparency.

1. Crises, acquisitions, and policy all suggest that conventional weapons are taking on a larger role deterring nuclear use. My new article in @intsecurity.bsky.social examines why US officials would consider conventional options when they have nuclear options available and how they might use them.

The DOGE firings have nothing to do with “efficiency” or “cutting waste.” They’re a direct push to weaken federal agencies perceived as liberal. This was evident from the start, and now the data confirms it: targeted agencies overwhelmingly those seen as more left-leaning. 🧵⬇️
Scatterplot titled “Empirical Evidence of Ideological Targeting in Federal Layoffs: Agencies seen as liberal are significantly more likely to face DOGE layoffs.”
	•	The x-axis represents Perceived Ideological Leaning of federal agencies, ranging from -2 (Most Liberal) to +2 (Most Conservative), based on survey responses from over 1,500 federal executives.
	•	The y-axis shows Agency Size (Number of Staff) on a logarithmic scale from 1,000 to 1,000,000.

Each point represents a federal agency:
	•	Red dots indicate agencies that experienced DOGE layoffs.
	•	Gray dots indicate agencies with no layoffs.

Key Observations:
	•	Liberal-leaning agencies (left side of the plot) are disproportionately represented among red dots, indicating higher layoff rates.
	•	Notable targeted agencies include:
	•	HHS (Health & Human Services)
	•	EPA (Environmental Protection Agency)
	•	NIH (National Institutes of Health)
	•	CFPB (Consumer Financial Protection Bureau)
	•	Dept. of Education
	•	USAID (U.S. Agency for International Development)
	•	The National Nuclear Security Administration (DOE), despite its conservative leaning (+1 on the scale), is an exception among targeted agencies.
	•	A notable outlier: the Department of Veterans Affairs (moderately conservative) also faced layoffs despite its size.

Takeaway:

The figure visually demonstrates that DOGE layoffs disproportionately targeted liberal-leaning agencies, supporting claims of ideological bias. The pattern reveals that layoffs were not driven by agency size or budget alone but were strongly associated with perceived ideology.

It would be really nice of them to tell us what the heck the US position actually is and why we need to threaten military action to force Putin to agree to something that presumably gives him everything he wants. Or maybe it's a strategy: Vance is a bad cop, Trump is a corrupt, drunk Russian cop.
