Institute member @sldelange.bsky.social, with @beatricedegraaf.bsky.social and @bartschuurman.bsky.social, argues in de Volkskrant that Europe is underestimating the two-front pressure on its liberal democracies โ€” from Moscow and Washington, backed by the far right in Europe.

Whereโ€™s the Sabotage? Repression, Recruitment, and Tactical Evolution in the U.S. Radical Environmental Movement. Thomas Zeitzoff   Why did the U.S. radical environmental movement shift away from tactics like arson and sabotage in the mid-2000s? And given the rising threat of climate change, why havenโ€™t these more contentious tactics made a comeback? This puzzle is particularly significant to scholars of terrorism because radical environmental groups like the Earth Liberation Front appear in major terrorism databases, and faced heavy repression from the government, despite causing no fatalities. I argue that repression and recruitment networks play a central role in shaping tactical repertoires. To test this theory, I combine original data on eco direct actions (1995โ€“2022), surveys, and interviews of activist experts. I find that repression sharply reduced the pace of direct actionsโ€”particularly sabotage and arsonโ€”and disrupted the punk and anarchist recruitment networks that had supported them. In their place, the climate justice movement emerged, favoring civil disobedience and mass protest over clandestine tactics. Repression thus altered the movement both directly (by targeting high-risk actors and their tactics) and indirectly (by reshaping recruitment pipelines). I conclude with a discussion of how climate politics, activist subcultures, repression, and the contested boundary of what constitutes terrorism may influence the future trajectory of radical environmentalism.

New in Terrorism & Political Violence: Why did radical environmental groups stop using arson & sabotage? And, given the threat from climate change why haven't those tactics returned?

My article "Where's the Sabotage" seeks to answer these questions.

The Russian economy is finally stagnating. What does it mean for the war โ€“ and for Putin? A wartime boom in Russia has given way to sluggish growth, tax hikes and squeezed public services. Will it affect the conflict in Ukraine?

Trumpโ€™s Devastating Plan for Ukraine The White House is giving Putin permission to try again.

Latest piece out in @theatlantic.com . Trump's "peace" plan for Ukraine, which he at this very moment trying to force on the country with threats and intimidation, is grotesque. The US president is admitting what too many refused to admit, he wants Putin to win. www.theatlantic.com/ideas/2025/1...

The Putin-Witkoff Plan Worsens the War Five Reasons the US should not help Russia subjugate Ukraine

We have a US administration trying to bully Ukrainians into accepting Russiaโ€™s proposal that their sovereignty be undone. Aside from the naked injustice of this, there are five basic practical reasons why it would make the world far more dangerous.

Key graph. IMO the main story here is the dramatic decline in the incidence of far right terrorism in 2024-25, not the slight increase in far left attacks (from ~3 to ~7 a year)
