Now officially ✨coauthors✨ w @stephofmann.bsky.social & @raffaelemstr.bsky.social because our ad hoc coalitions paper is out in open access in @risjnl.bsky.social Read Raffa’s thread about the article ⬇️

Raffaele Mastrorocco@raffaelemstr.bsky.social · 4w ago

The debate over the "demise of multilateralism" often treats these flexible coalitions as evidence that international order is unravelling. @stephofmann.bsky.social @anaprokhorov.bsky.social and I did some archival digging and found that AHCs have always been part of the global governance toolkit.

New week, new (open access) publication! 🚨 @risjnl.bsky.social Why are ad hoc coalitions (AHCs) created, and how do they vary in their composition and afterlife? @eui-eu.bsky.social @eui-sps.bsky.social @eui-schuman.bsky.social www.cambridge.org/core/journal...

Challenger parties don't just confront mainstream foreign policies-they redefine what counts as national security in the first place. New open-access article on political entrepreneurs and foreign and security policy⬇️ link.springer.com/article/10.1... @jird-jour.bsky.social @eui-sps.bsky.social

The emergence and election of new parties challenging mainstream status quo in democratic countries is one of the most critical features affecting the definition of national security priorities today....

Great place to spend the day working, gorgeous @eui-eu.bsky.social garden. Thanks Firenze! @raffaelemstr.bsky.social

Last week Trump withdrew from 66 international orgs (formal and informal) & treaties. Here's a great analysis. It's common practice for donors to review intl' institutions. BUT never seen such a mass withdrawal. @raffaelemstr.bsky.social @borzyskowski.bsky.social share.google/eeZrt1pndwVf...

Because I have been such a good boy (once again), 🎅 has an early present for me: here's a brand-new (open access) article discussing the use of #radicalright as a concept in current scholarship. And if that wasn't already great (it is), there's more 1/3

Now assigned to the latest issue of International Politics! With the new US National Security Strategy, it's the 'perfect' timing to reflect on the implications of the far-right on European security - a topic I discuss in this article: link.springer.com/article/10.1...

What kind of vision(s)? The far-right and European security - International Politics

Far-right parties are now widespread in different countries across Europe, raising questions about states’ commitment to European security. These parties varied their positions on the Russian invasion...

Had such a great and productive time with these amazing people in Rapallo for the Exploratory Symposia @europeanisa.bsky.social ! Perhaps we’re smiling too much for discussing the Far-Right in International Politics, but how can you blame us considering our project’s progresses and that view!

@ninahall.bsky.social · 9mo ago

In Naples for #SISP25 all week - chairing & presenting on the far-right, multilateralism, and security policy 🌍 Let’s catch up over coffee if you’re around! ☕ #IR #FarRight #Security #IOs #

📢 Excited for #ECPR2025 in Thessaloniki tomorrow! Join our panel “International Politics and the Far-Right” (10:45–12:30h)! I'll present my paper on far-right strategies in security IOs, alongside 3 other great papers & @stephofmann.bsky.social as a discussant. More here: ecpr.eu/Events/Event...

What Brothers of Italy shares with its post-fascist predecessors

Does Giorgia Meloni’s Brothers of Italy share similarities with its post-fascist predecessors? New research finds a mixed picture of continuity and change.

Excited to be heading to Rapallo, Italy for @europeanisa.bsky.social Exploratory Symposia w/ @raffaelemstr.bsky.social & Prof. Lisbeth Zimmerman & others. We will discuss role & impact of Far-Right Parties in International Relations. Thanks to EISA for opportunity 🙏

Happy to have contributed a piece on the far right to the anniversary report of the Karlspreis. The impact of the far right does not only depend on seats or government participation. Their success erodes support for international collaboration because other parties accommodate and legitimize them.

Last day to apply!

1. Are contagion concerns warranted? Political contagion risks are real, both in public opinion, and in terms of public discourse. We document both encouragement and deterrence effects and show that IO’s responses influence whether encouragement or deterrence dominates. 8/20
