Tzili Reshef is a prominent Israeli peace activist and co-founder of Peace Now, one of Israel's leading organizations advocating for peace with the Palestinians. Established in 1978, Peace Now emerged from a group of reserve soldiers who protested the Israeli government's policies during the Lebanon War, and Reshef played a key role in its formation alongside Ari Shavit and others. Known for her long-term advocacy for Israeli-Palestinian peace and human rights, her activism has focused on promoting a two-state solution, opposing settlement expansion in the occupied territories, and fostering dialogue between Israelis and Palestinians to achieve human rights and security for both sides. Reshef's efforts have included organizing demonstrations, engaging in public advocacy, and collaborating with international peace groups to highlight the need for compromise and reconciliation in the region.

Over decades, Reshef has remained a steadfast voice for moderation and justice amid escalating conflicts, criticizing both Israeli government actions and Palestinian militancy when they undermine peace prospects. She has contributed to educational initiatives and interfaith dialogues aimed at building empathy across divides. Despite facing opposition from nationalist elements in Israel, her work has been recognized for its moral clarity and dedication to non-violent resolution, influencing generations of activists and policymakers committed to ending the Israeli-Palestinian conflict.
