Why the Diaspora Is Not Enough

For generations, American Jews imagined they could construct a full Jewish life in exile. With thriving synagogues, day schools, cultural institutions, and philanthropic infrastructure, the Diaspora seemed to offer stability, prosperity, and moral standing. Zion, for many, became a symbol or a cause—noble, but optional. But October 7 shattered that illusion. When Jewish blood was spilled with impunity and elite Western institutions met it with equivocation or celebration, it became painfully clear: the Diaspora is not enough. Judaism without Israel is a tree severed from its roots, a body without a spine.

The Diaspora has given rise to extraordinary Torah scholarship, creativity, and resilience. It has produced Rishonim in medieval Spain, Hasidic dynasties in Eastern Europe, and a vibrant postwar American Jewish culture. Yet it has always been a condition of compromise. Diaspora Judaism is adaptive, not native. It is structured by its minority status, shaped by external permission, and oriented toward survival. It is reactive, often waiting for the next crisis—or the next chance to justify itself before Gentile society. Its prayers point east, to a home it does not occupy.

American Jewry, for all its achievements, often sustains itself on nostalgia and philanthropy rather than covenantal ambition. The institutions are impressive, but their foundations are fragile. As Rabbi Soloveitchik wrote in Kol Dodi Dofek, the Jewish people are not merely a faith community but a metaphysical nation. Exile cannot fulfill that destiny.

Some Jewish thinkers have proposed a different vision. Simon Rawidowicz famously described Jews as “the ever-dying people,” resilient through dispersion and adaptive reinvention. Mordecai Kaplan, the father of Reconstructionist Judaism, argued that Judaism was an evolving religious civilization not bound to land or statehood. More recently, scholars like Noam Pianko have advocated for a post-Zionist understanding of peoplehood, one that emphasizes global networks over territorial nationhood. While these perspectives offer insight into Jewish continuity, they are ultimately untenable as a foundation for the Jewish future.

First, because Jewish liturgy itself refutes them. Three times daily, Jews pray for the return to Zion, the rebuilding of Jerusalem, and the restoration of the Temple. The Amidah, the Musaf, even Birkat HaMazon—these texts are saturated with longing for national return. To argue that Judaism can be territorially agnostic is to turn our most ancient and persistent prayers into dead metaphors. As Rabbi Abraham Joshua Heschel wrote, “Prayer is meaningless unless it is subversive.” A Diaspora Judaism that severs itself from Israel must neutralize its own prayers to remain coherent.

Second, because exile is never truly safe. The modern liberal Jewish belief in tolerance and inclusion was exposed as a fantasy after October 7. Jews who believed that elite credentials, progressive values, or social capital would protect them were quickly disabused of that notion. Within hours, posters of kidnapped Israeli children were torn down in Ivy League courtyards. Faculty members excused murder. Major cultural figures rationalized terror. History repeats: Spain, Germany, Iraq, Iran—Jews thrived until they didn’t. The exile is generous until it turns jealous. Only one country in the world scrambles fighter jets to save Jewish lives. That is not a symbolic fact. It is covenantal reality.

Third, the Torah itself commands us toward the Land. A full third of the 613 mitzvot—agricultural, judicial, national—can only be fulfilled in Eretz Yisrael. The Ramban, in his commentary on Vayikra 18:25, argues that mitzvot performed in exile are preparatory, “so that we will not forget how to do them when we return.” The Sifrei teaches that observance outside the Land is like a training ground. Galut, in this view, is pedagogical—but temporary. A Judaism permanently unmoored from the Land is halakhically amputated.

Fourth, only Israel forces us to confront the ethical challenges of Jewish power. Diaspora Jews often pride themselves on moral clarity, but they do so from positions of comfortable marginality. In Israel, Jews must govern. They must legislate, defend, tax, and build. Halakhah is no longer a private spiritual code; it becomes the framework for courts, armies, and economies. As Rav Kook argued, the return to Zion is not only physical but spiritual: it forces Torah to encounter the concrete.

Israel is not just a response to the Holocaust. It is not merely a refuge. It is the axis of Jewish history, the vessel for redemption, the theater where Jewish sovereignty, responsibility, and prophetic vision are tested and lived. The Land of Israel is not a backdrop—it is a protagonist in the Jewish story. It is the setting of the covenant. As Rabbi Sacks wrote, “Israel is the only place where Jews can construct a society in accordance with Jewish ideals.”

October 7 revealed something else: the cost of Jewish disunity. In exile, Jewish identity is often attenuated—cultural, nostalgic, abstract. In Israel, it is concrete. The IDF soldier, the farmer in the Negev, the paramedic in Sderot—they are Judaism in action. They are not relics of faith; they are its future. When the Diaspora is unwilling to see this, or worse, when it judges Israel by abstract moralisms that ignore history, theology, and threat, it fractures the very peoplehood it claims to preserve.

Judaism needs the Diaspora’s creativity, intellect, and spiritual diversity. But the Diaspora cannot fulfill the covenant alone. It cannot carry the full weight of Torah, of sovereignty, of safety, of future. It can be a partner—but not a substitute.

The Jewish mission is national, geographic, covenantal, and prophetic. It lives in Hebrew, in Jerusalem, in the restoration of Jewish agriculture, courts, and self-defense. It lives where Jewish history began and where, God willing, it will reach its final chapter.

We need both Israel and the Diaspora. But only one is the heart. Judaism needs Israel. The Diaspora is not enough.
