Dismantelling a Gallery of Horrors: Radicialization and Extremism in Europe after October 7th 2023

The paper analyses the impact of Israel-Palestinian conflict on violent radicalisation and extremism in Europe, starting from the attacks of October 7^th 2023. After having defined these keywords (radicalisation and violent extremism) and the general background, the paper is focused on the radicalisation of the public sphere and on the mobilisation of sociopolitical movements, included antisystem actors. Starting from a rethinking of the sociology of Subjects by Alain Touraine, in relation with the theory of radicalisation, the paper utilises a set of different data and sources to support two main conclusions: the first one, the ongoing conflict is catalyst and multiplier of long-term trends of radicalisation within European society; particularly about the re-configuration of antisemitism and islamophobia in the far-right arena. The second one, in order to tackle all this, it is fundamental to give a more important role to a universalistic rationality based on human rights and dignity in the public sphere.
