Jewish Responses to Terrorism: Faith, Resilience, and Ethics

When the Sanctuary Is Breached

On October 27, 2018, a gunman entered the Tree of Life synagogue in Pittsburgh during Shabbat morning services and murdered eleven worshippers. It was the deadliest attack on Jews in American history. The victims were doing what Jews had done on Saturday mornings for millennia: praying, singing, welcoming one another.

The Pittsburgh attack was not the first time terrorists targeted Jews at prayer — and tragically, not the last. From Jerusalem to Buenos Aires, from Mumbai to Halle, Jewish communities have faced violence aimed at their most vulnerable moments. How Judaism responds to this reality — spiritually, ethically, and practically — reveals the tradition’s deepest values.

The Right of Self-Defense

Jewish tradition unambiguously affirms the right of self-defense. The Talmud states: “If someone comes to kill you, rise up and kill them first” (Sanhedrin 72a). This is not a permission — it is an obligation. Pikuach nefesh — the preservation of life — overrides nearly every other commandment.

In the context of terrorism, this principle supports robust security measures: protecting synagogues, pursuing terrorists, and using force when necessary to prevent attacks. Israeli security doctrine, forged through decades of confronting terrorism, reflects this principle in practice.

Ethical Constraints

But self-defense in Jewish ethics is never unlimited. The tradition imposes constraints:

Proportionality: Response must be proportionate to the threat. Excessive force is prohibited. The Talmud discusses the concept of a “pursuer” (rodef) and limits the use of lethal force to situations where lesser measures would not suffice.

Distinction: Jewish military ethics, as codified by Maimonides and developed by modern authorities, distinguish between combatants and civilians. Deliberately targeting civilians is prohibited.

Moral integrity: Perhaps the most important constraint is the insistence that responding to evil must not make one evil. The Torah commands: “You shall not hate your brother in your heart” (Leviticus 19:17). The goal of security is to protect life, not to dehumanize enemies.

Resilience as Response

One of the most consistent Jewish responses to terrorism is the decision to continue. After every attack — on buses in Jerusalem, on a community center in Buenos Aires, on synagogues in Pittsburgh and Poway — Jewish communities have returned to the sites of violence and resumed their activities.

This is not denial or naivety. It is a deliberate theological statement: terrorism aims to destroy Jewish life through fear. Continuing to live, pray, gather, and celebrate is an act of resistance. The Jewish people, having survived centuries of persecution, have developed resilience as a communal muscle.

After Pittsburgh, the rallying cry was “Show Up For Shabbat” — an invitation for Jews everywhere to attend Shabbat services the following week. Synagogues across America were packed.

The Israeli Experience

Israel has confronted terrorism on a scale that no other Jewish community has experienced. The waves of attacks — airplane hijackings, bus bombings, stabbings, rockets — have shaped Israeli society, security doctrine, and public consciousness.

Israeli responses have included military operations, security barriers, intelligence gathering, and targeted operations against terrorist infrastructure. These measures have been effective in reducing attacks but have also generated ethical debates — within Israeli society and internationally — about proportionality, civilian impact, and long-term consequences.

Mourning and Memory

Jewish tradition provides structured ways to process grief. After terrorist attacks, communities have drawn on these resources: sitting shiva collectively, reciting Kaddish for victims, naming the dead during El Maleh Rachamim prayers, and establishing permanent memorials.

In Israel, Yom HaZikaron (Memorial Day) includes remembrance of terrorism victims alongside fallen soldiers. The day’s observance — with sirens, ceremonies, and candle lighting — gives national expression to private grief.

The Enduring Question

Terrorism poses the ultimate test of a community’s values: can you remain who you are under the pressure of violence? Jewish tradition answers that security and ethics are not opposites — they are complementary requirements. Protecting life is a commandment. So is maintaining moral standards. The challenge is doing both simultaneously, without sacrificing either.
