At its 2025 National Convention this past weekend, the Democratic Socialists of America adopted a contentious resolution titled “For a Fighting Anti-Zionist DSA,” further crystallizing the far-left organization’s anti-Israel views.

The measure, which passed by a margin of 56 percent to 43 percent, “unequivocally affirms” the DSA’s “commitment” to the Thawabit, a Palestinian nationalist framework that includes the so-called “right of return” for millions of Palestinians and their descendants, claims to Jerusalem as a Palestinian capital, and explicit support for so-called “resistance” against Israel. Palestinian leaders and activists have described the Thawabit as a set of principles aimed at eliminating Israel and establishing a Palestinian state in its place.

The DSA, the largest socialist organization in the US which counts members of the US Congress among its ranks, has previously opposed US military aid to Israel and supported the boycott, divestment, and sanctions (BDS) movement against the Jewish state. However, the resolution passed on Sunday marks an escalation.

According to the resolution, various actions in support of Israel, such as “making statements that ‘Israel has a right to defend itself'” and “endorsing statements equating anti-Zionism with antisemitism,” will now be considered an “expellable offense,” subject to a vote by the DSA’s National Political Committee.

The resolution’s passage underscores the widening gulf in the US between far-left activists and mainstream Democrats, who have generally supported Israel’s right to self-defense and to live in security even if they’ve been critical of the Israeli war effort in Gaza. DSA members celebrated the vote as a bold stand for Palestinian liberation, but some observers have suggested that it could alienate allies and normalize extremist rhetoric.

With roughly 78,000 members nationwide, the DSA represents a small fraction of the Democratic Party’s base. But its convention votes often reverberate in progressive political spaces.

DSA has ramped up its anti-Israel rhetoric during the Gaza war. On Oct. 7, 2023, the organization issued a statement saying that Hamas’s massacre across southern Israel that day was “a direct result of Israel’s apartheid regime.” The organization also encouraged its followers to attend an Oct. 8 “All Out for Palestine” event in Manhattan.

In January 2024, DSA issued a statement calling for an “end to diplomatic and military support of Israel.” Then in April, the organization’s international committee, DSA IC, issued a missive defending Iran’s right to “self-defense” against Israel. Iranian leaders regularly call for the Jewish state’s destruction, and Tehran has long provided Hamas with weapons and funding.

The vote also comes amid the political ascendence of New York City Democratic mayoral nominee Zohran Mamdani, a high-profile DSA member and outspoken critic of Israel. Mamdani, who has called Israel an “apartheid state” and endorsed boycotts of Israeli institutions, has established himself as a leading voice for the party’s anti-Zionist wing.
