Ella Keidar Greenberg and Iddo Elam of Mesarvot are two young Israeli "refuseniks", conscientious objectors who refused to serve in the Israeli military, and went to jail for that. Refusing to serve in an army historically involved in an illegal occupation, which is committing genocide, should be the most obvious choice. However, people in Israel who do not serve in the military are usually considered outcasts, or traitors when they refuse.
We met them a few months ago in Naples.
