It is often assumed that the 1967 Arab-Israeli War led to the "wholesale conversion of the Jews to Zionism," as Norman Podhoretz famously phrased it. This "conversion" is equally, if often less explicitly, said to coincide with the end of the era of Jewish marginality in the U.S. and West more broadly, as Jews of European descent were half-included, half-conscripted, into normative structures of whiteness, class ascension, and citizenship. While this epochal shift in Jewish racial formation and political allegiance is undeniable especially in the context of large Jewish secular and religious institutions, at the time this "conversion" was seen as anything but inevitable. Many Jewish liberals, including Irving Howe, Seymour Lipset, and Nathan Glazer, and reactionaries such as Meir Kahane, saw Jewish overrepresentation and hypervisibility in New Left organizations such as Students for a Democratic Society, the Youth International Party, and the Socialist Workers Party as a sign that Jewish youth rejected Zionism as well as the Jewish rise into the middle class. That retrospectively we see Jewish racial formation and political alignment after 1967 as a fait accompli often relies on the erasure not only of mass Jewish participation in the New Left, but also the erasure of the New Left's anti-imperialist political commitments, including critique of expansive Israeli militarism and the settler colonial assumptions underlying Zionism. Looking at memoirs, pamphlets, histories, and original interviews with Jewish participants in the New Left, this article excavates the political alignments of Jewish New Left activists, exploring opposition to the U.S.'s new support of the Israeli state as well as the changing Ashkenazi Jewish racial assignment. Rather than finding Third World and Black Power critiques of Israel antisemitic, it was precisely the Jewish New Left's politics of international and multiracial solidarity that encouraged their support for Black Power critiques of Zionism. In this way, Jewish members of the New Left also attempted to critically challenge their own whiteness, aligning support for Israel after 1967 with support for the racial and economic structures of militarism and capitalism at home.
