Alexandria Ocasio-Cortez and Rashida Tlaib are members of the Democratic Socialists of America (DSA). The DSA is opposed to Zionism and Israel. As late as 2012, one former DSA leader described the group as "the place to go on the left if you were a socialist and you were pro-Israel". The group’s founders found common cause with progressives inside the Jewish state, embracing rank-and-file socialists there as well as political leaders like former prime minister Shimon Peres. Not anymore. Anti-Zionist activism and rhetoric are not new phenomena in American left-wing politics. Previously, the staunchly anti-Communist DSA saw no contradiction between being pro-Israel, or at least pro-left-wing-Israel, and being a proud socialist. That changed with Boycott, Divestment and Sanctions against Israel (BDS). BDS aims to pressure the Jewish state into changing its policies toward the Palestinian Arab populations within Israel. A Palestinian flag was waved at DSA meetings. By the way, Bernie Sanders has never been a member of the DSA.
