Left-Wing Extremism and Antisemitism

Rethinking the Fight against Antisemitism after October 7

In this new episode on antisemitic violence, Dr Hans-Jakob Schindler speaks with Alexander Ritzmann about his latest report, which calls for a shift from incident response to “strategic disruption” of extremist networks, finances, and coordinators, and for treating antisemitism as a security threat. The discussion in this episode is based on Rethinking the Fight against Antisemitism after October 7 [https://www.counterextremism.com/press/current-responses-miss-real-drivers-antisemitic-violence-tackle-networks-not-incidents-says] by Alexander Ritzmann, published in May 2026 by the Counter Extremism Project.

Left-Wing Extremism and Antisemitism

Dr Hans-Jakob Schindler and Alexander Ritzmann are joined by journalist and author Nicholas Potter—who has faced death threats and intimidation because of his work—to discuss the rise in left-wing extremism and antisemitism. They talk about groups on the left that put aside ideological differences to create larger networks united in anti-democratic, illiberal and antisemitic causes.  Further reading: The New Authoritarian Left: An Acute Threat to Democratic Society [https://www.dtv.de/buch/die-neue-autoritaere-linke-26448] by Nicholas Potter.

Disinformation and 'The Noise War'

Dr Hans-Jakob Schindler and Alexander Ritzmann are joined by JJ Green—journalist and author of The Noise War—to unpack the mechanics of disinformation: how to spot it, why it works, how it corrodes trust and fractures nations, and what can be done to fight back in an age of constant information warfare.

Islamic State's Propaganda Evolution Since October 7

Dr Hans-Jakob Schindler and Alexander Ritzmann are joined by Sean McCafferty to discuss how the October 7 attacks changed online extremism, including Islamic State’s (IS) response. Since IS lost its final territorial holdout in Baghuz, Syria, in March 2019, the group’s global presence, propaganda output, and online ecosystem have evolved significantly, including to a more decentralised approach, characterised by a surge in output from its regional affiliates in Africa and South Asia. Sean is EU GLOCTER PhD Fellow, seconded to CEP and author of a blog post on Islamic State Propaganda Evolution Since October 7 [https://www.counterextremism.com/blog/islamic-state-propaganda-evolution-october-7-content] which is part of CEP’s CounterPoint series [https://www.counterextremism.com/news-and-media/blog].
