Special Issue on Violent Extremism 2026

A photo showing a dim, cluttered teenager's bedroom viewed at dusk, with a large window revealing a burning, apocalyptic cityscape glowing orange through partially raised blinds and curtains. Inside are an unmade bed, a wooden chair, a glowing computer monitor on a messy desk, scattered cables, and photographs taped to the walls—visually evoking youth isolation, dystopian worldviews, and radicalization themes discussed in the article.

By Cécile Rousseau & Samuel Veissière

July 20, 2026

A conceptual illustration showing a lone figure in a green shirt walking along a crumbling stone path that disintegrates into scattered fragments and fiery orange chaos on the right. The left depicts a serene green landscape with a setting sun, rolling hills, and trees, symbolizing the fragmentation of ideological frameworks and the collapse of defined structures into disordered violent extremism.

By Clark McCauley

July 17, 2026

$A conceptual double-exposure photo showing a young adolescent's face blended with a cracked, weathered wall texture, symbolizing political alienation and disillusionment. The left half reveals the youth's serious expression while the right dissolves into fractured, peeling surfaces, visually representing distrust, powerlessness, and psychological fragmentation associated with the pathway from system-disillusionment toward political radicalism in Swedish adolescents.$

By Marta Miklikowska & Tomasz Besta

July 14, 2026

$A photo showing a fragmented, close-up human face in muted blue-gray tones, overlaid with distorted textures and streaks of vivid red. The image is heavily manipulated with cracked, glass-like fractures and double-exposure effects that obscure the eyes, evoking themes of psychological rupture, obscured identity, and violence—visually paralleling the article's discussion of ideology-free extremism fixated on aggression itself.$

By Quassim Cassam

July 9, 2026 (Cited by: 1)

A photo showing a close-up impasto oil painting of a human face composed of fragmented, palette-knife patches in blue, orange, yellow, red, and white. The mosaic-like brushstrokes assemble piercing blue eyes, nose, and mouth from disparate color blocks, visually evoking the article's "salad bar" metaphor of composite, hybrid extremist worldviews built from diverse ideological fragments.

$A mixed-media collage portrait showing a faceless human figure constructed from torn paper fragments in muted tones of beige, gray, blue, and brown. The fractured, layered composition assembles disparate scraps into a single ambiguous form, visually evoking the article's theme of fragmented, patchwork ideologies and the conceptual incoherence behind "salad bar" extremism, where contradictory pieces combine into one unstable identity.$
