Ronnie Barkan is an Israeli dissident, co-founder of Boycott from Within, past member of Anarchists Against the Wall and Palestine Action. On Nakba Day 2022 he participated in a direct action against the UK headquarters of Israel-based Elbit Systems. In 2025 the site was permanently shut down. Elbit is Israel's #1 arms manufacturer and currently has boots on the ground in Gaza who help to carry out the genocide.

More recently Barkan was harassed by the German secret police following his Munich talk at Professor-Huber-Platz, where he connected the legacy of the White Rose who opposed Nazism with direct action in opposition to Zionism.
