Polarization, Influence, and Fragmentation

Nicole Deitelhoff at the Czech Security Forum 2026

On October 22, Nicole Deitelhoff participated in the Czech Security Forum in Prague, where she joined other guests in a discussion on NATO and the future of European security. Under the title “Polarization, Inter­ference, and Frag­mentation of the Western Alliance,” this year’s con­ference focused on the funda­mental trans­formation of the "West" from a relatively stable geo­political bloc into a frag­mented and internally contested entity. The event was organized by the Institute of Inter­national Relations Prague and the Peace Research Center Prague, and supported by a number of inter­national actors. 

Following a key­note speech by Brett Ashley Leeds (Rice University) on the current state of U.S. relations with military alliances and the potential im­plications for its allies, Nicole Deitel­hoff spoke with Jim Stokes, former Director of Nuclear Policy at NATO, and Lauren Sukin (University of Oxford) about Russia as a threat to NATO, Europe’s potential, and the im­portance of stronger cooperation among the relevant actors. She emphasized: “The weaker trans­atlantic relations are, the weaker Europe is.” She pointed out the challenge for Europe not only to com­pensate for the declining military support from the U.S. but also to assume greater responsibility within NATO – a move currently being called into question by domestic political dynamics in countries such as France and Germany. 

The conference was held in co­operation with the Institute of Inter­national Studies and the Faculty of Social Sciences at Charles University in Prague, the Prague office of the Friedrich Ebert Foundation, and the embassies of Norway and Denmark in Prague. It was funded as part of the INTERFER project of the European Regional Develop­ment Fund.
