Is the US about to be humiliated on the world’s most prestigious cultural stage?

More than 70 prominent international artists have signed an open letter demanding the exclusion of the United States, Israel, and Russia from the 2026 Venice Biennale, accusing those governments of committing war crimes and atrocities.

At the Venice Biennale, protests, self-mutilation and rage against Israel and Russia. Is anyone left to talk about the art?

At the 61st Venice Biennale, protests and controversies have overshadowed the art itself. The Art Not Genocide Alliance (ANGA) demonstrated against the inclusion of Israel and Russia, while the Israeli Pavilion became a flashpoint. Artist Belu-Simion Fainaru, presenting his installation "Rose of Nothingness" in a temporary space, complained that he was forced to defend his art's right to exist amid questions about politics rather than his work. The Biennale also saw barricades, strikes, the resignation of the Golden Lion jury, Iran's last-minute withdrawal, and anger directed at the American pavilion over Trump administration policies. The central exhibition, "In Minor Keys," curated by the late Koyo Kouoh, was eclipsed by these events.
