The Five Principles of the Jewish Defense League

The Five Principles of the Jewish Defense League form the ideological core established by Rabbi Meir Kahane when he founded the organization in New York in 1968. Drawn from biblical, Talmudic, and rabbinic sources, they were articulated as a response to rising antisemitism in urban America, the perceived passivity of much of the Jewish community after the Holocaust, the plight of Soviet Jewry, and a broader conviction that Jewish survival required a decisive break from historical patterns of vulnerability.

Kahane presented them as practical and spiritual foundations for Jewish self-respect, mutual responsibility, and readiness. They appear in consistent form across JDL materials and are summarized in standard accounts as follows (with the exact phrasings commonly associated with the group):

1. Love of Jewry (Ahavat Yisrael)

2. Dignity and Pride (Hadar)

3. Iron (Barzel)

4. Discipline and Unity (Mishmaat)

5. Faith in the Indestructibility of the Jewish People (Bitachon)

These principles are not abstract slogans. They constitute an integrated system of Jewish national and religious consciousness designed to reverse centuries of powerlessness and to restore the Jewish people to a posture of strength, unity, and faith. Below is a full exposition of each principle, drawing on the classical formulations associated with the JDL, the teachings of Rabbi Meir Kahane, and the expanded explanations preserved in JDL 613 materials.

1. Ahavat Yisrael — Love of Jewry / Love of the Jewish People

Official framing: “LOVE OF JEWRY, one Jewish people, indivisible and united, from which flows the love for and the feeling of pain of all Jews.”

This principle asserts that the Jewish people constitute a single, organic nation that transcends geography, denomination, political affiliation, or level of religious observance. The pain of any Jew—whether in Brooklyn, Moscow, Damascus, or Jerusalem—is the pain of every Jew. There are not “American Jews,” “Soviet Jews,” or “Israeli Jews” in any ultimate sense; there are only Jews who happen to live in those places.

Kahane rooted this in the classic Talmudic teaching Kol Yisrael arevim zeh bazeh (“All Israel are responsible for one another” — Shevuot 39a and related sources). He insisted that this mutual responsibility is not sentimental or optional. It demands concrete solidarity: physical, political, financial, and emotional. When Jews in one community ignore the suffering of Jews elsewhere, they violate the covenant of peoplehood and weaken the entire nation.

In the late 1960s and 1970s context, Ahavat Yisrael fueled the JDL’s high-profile campaigns on behalf of Soviet Jewry, its insistence that American Jews stop treating the Holocaust as a closed chapter, and its rejection of any hierarchy that ranked some Jews as more “worthy” of defense than others. It also underpinned the slogan that the Jew ultimately can look only to another Jew for reliable help, and that the long-term solution to Jewish insecurity lies in the return of the people to its land (Eretz Yisrael).

For a contemporary expression, the principle continues to demand that Jewish organizations and individuals refuse to fragment the people along lines of politics, ritual practice, or geography. Love of Jewry is measured by willingness to feel—and act upon—the vulnerability of the most endangered Jew as if it were one’s own. It rejects the modern tendency to treat Jewish identity as a private lifestyle choice or an ethnic hobby. Instead, it insists that every Jew is bound by an unbreakable covenant of shared destiny. When one Jew is attacked, the entire people is attacked. When one Jew is abandoned, the entire people is diminished.

This love is not passive affection. It is an active obligation that requires Jews to prioritize the safety, dignity, and continuity of the Jewish people above personal comfort, political fashion, or the approval of the non-Jewish world. Ahavat Yisrael is the emotional and moral foundation upon which all the other principles rest. Without it, pride becomes empty nationalism, strength becomes mere aggression, discipline becomes sterile organization, and faith becomes abstract theology.

2. Hadar — Dignity and Pride / Jewish Pride

Official framing: “DIGNITY AND PRIDE, pride in and knowledge of Jewish tradition, faith, culture, land, history, strength, pain and peoplehood.”

Hadar rejects the apologetic, self-effacing posture that Kahane believed had characterized too much of Jewish life in the Diaspora (the “galut mentality”). It calls for open, unembarrassed pride in Jewish identity: the Torah and its commandments, the historical experience of the people (including both glory and suffering), the Hebrew language and culture, the Land of Israel, and the unique national-religious destiny of the Jewish people.

The Jewish nation is unlike any other nation on earth. We have survived the test of time from the ancient Egyptians and the evil Pharaoh, to the Babylonians, Assyrians, Greeks, Romans, and through the Crusades and Inquisitions. We have endured. Even the evil of the Nazi genocide of World War II and the silence of the free world could not destroy our people. All of these peoples and cultures are either extinct or have been defeated, with our people left standing in the triumph of survival.

G-d promised Abraham that the Jewish people would never be destroyed: “I will bless them that bless thee and curse them that curse thee…” and surely all those that sought our destruction have been cursed with failure.

We Jews today must take pride in our heritage, which exemplifies the victory of the few against the many and the good against the evil. We are a chosen nation and a holy nation that was freed from bondage in Egypt and brought to Mount Sinai to accept G-d’s law and this special status unique to our people.

Rabbi Kahane’s mentor, Ze’ev Vladimir Jabotinsky, taught that “Even in poverty a Jew is a prince.” It is this notion that brought our people out of the ashes of the Holocaust into the glory of the rebirth of the Jewish commonwealth.

This is not empty nationalism. Kahane argued that genuine dignity requires knowledge. A Jew who does not know his own history, texts, and collective story cannot stand tall; he remains dependent on the definitions and approval of others. Hadar therefore includes education in Jewish sources, celebration of Jewish achievement, and refusal to internalize the caricatures or accusations leveled against the Jewish people.

In practice, the principle sought to reverse the image of the Jew as perpetual victim or perpetual accommodator. It encouraged Jews to walk with upright posture, to defend Jewish honor in public, and to treat Jewish identity as a primary, non-negotiable fact rather than a private ethnic quirk to be downplayed for the sake of social acceptance. After the Holocaust and amid urban antisemitism in the 1960s, Kahane presented Hadar as psychological and cultural self-defense: a people that is ashamed of itself will not fight effectively for its survival.

Hadar demands that Jews stop seeking validation from the surrounding culture and instead draw strength from their own unbroken chain of tradition, suffering, and triumph. It is the refusal to apologize for Jewish particularism, for Jewish survival, or for Jewish strength. A people that knows its own greatness will neither hide nor beg.

3. Barzel — Iron / Jewish Strength

Official framing: “IRON, the need to both move to help Jews everywhere and to change the Jewish image through sacrifice and all necessary means—even strength, force and violence.”

Literally Barzel means iron. However, we take it to mean Jewish strength. A Jew must be strong in both mind and body. He must be trained and prepared to deal with any situation that should arise with a strong body and an acute mind. When iron is subject to fire it gets stronger; so too when the Jewish Nation comes under fire they must be forged with the strength to survive and persevere.

Until the concept of Barzel was brought to the world by the Jewish Defense League and their predecessors, the Irgun and the Lechi, our people learned the lesson that a smart Jewish mind must be accompanied by a Jewish fist of iron… Barzel.

Every Jewish victory in the history of our people—from the military genius of David Hamelech to the Maccabees and finally, with the rebirth of the Jewish Commonwealth in Eretz Yisrael—exemplified the meaning of Barzel.

Barzel is the principle of readiness. It insists that love of the Jewish people and pride in Jewish identity are incomplete without the capacity and will to defend them. Kahane taught that centuries of Jewish powerlessness had produced a distorted self-image and had invited aggression. The Holocaust, in his view, was the ultimate consequence of that weakness. “Never Again” therefore required not only memory but a transformed Jewish posture: the willingness to use strength when necessary.

The principle does not glorify violence for its own sake. It frames physical force, when employed, as a last resort in the service of Jewish survival and dignity, and as a means of altering the perception that Jews can be attacked with impunity. Barzel calls for personal and collective preparedness, the rejection of passive reliance on others for protection, and the acceptance that sacrifice—including personal risk—may be required to protect Jewish lives and honor.

Historically, this principle shaped the JDL’s self-defense training, its confrontational demonstrations, and its public messaging that Jews would no longer absorb blows without response. It remains the most controversial of the five principles precisely because it refuses to rule out force in advance. Kahane maintained that a people that declares itself forever non-violent in the face of existential threat has already chosen defeat.

Barzel is the practical expression of the refusal to be perpetual victims. It is the recognition that moral superiority without the power to defend that morality is an invitation to destruction. A Jewish people that possesses both mind and iron is a people that cannot be easily erased.

4. Mishmaat — Discipline and Unity / Jewish Discipline

Official framing: “DISCIPLINE AND UNITY, the knowledge that he (or she) can and will do whatever must be done, and the unity and strength of willpower to bring this into reality.”

Mishmaat (also rendered Mishmat) is Hebrew for discipline. We define it as mental, physical, and spiritual discipline. It is discipline that leads a Jew to take personal risks to defend principles that are central to the Torah and its commandments.

Throughout our history, all of our great achievements as a people involved discipline in the form of mesirut nefesh—risking of one’s physical safety for the survival of the Jewish people.

In the story of Purim, Mordechai the Jew showed mishmat by not bowing down to Haman. As it states in the Book of Esther, “…and Mordechai would not bow down…”. All the leaders of his generation bowed down to Haman in the same way that many Jewish leaders today cave in to pressure from the nations of the world.

It is precisely by not giving in to pressure from the world and staying true to our faith and culture that we will persevere.

Kahane and JDL literature repeatedly stated that lack of discipline and internal division had historically contributed to Jewish catastrophe, while unity and self-discipline had produced strength and success. Mishmaat therefore demands both personal self-mastery and collective cohesion.

Individually, it means the ability to control impulses, accept hierarchy and organization when necessary, and subordinate private comfort to communal necessity. Collectively, it means ending the factionalism, mutual distrust, and organizational rivalries that prevent Jews from acting as one people. The principle holds that scattered, undisciplined individuals—even if each is brave—cannot match the effectiveness of a coordinated body.

In JDL teaching, Mishmaat was the practical counterpart to Ahavat Yisrael: love without discipline remains ineffective sentiment. It called for structured activism, clear chains of responsibility, and the cultivation of willpower strong enough to carry out difficult or unpopular actions when Jewish interests required them. Historical examples of Jewish disunity (from the Second Temple period through modern communal politics) were cited as cautionary lessons.

Mishmaat is the force that turns private conviction into public power. Without it, the other principles remain theoretical. With it, Jews become capable of sustained, organized, and effective action on behalf of their people.

5. Bitachon — Faith in the Indestructibility of the Jewish People

Official framing: “FAITH IN THE INDESTRUCTIBILITY OF THE JEWISH PEOPLE, faith in the greatness and indestructibility of the Jewish people, our religion and our Land of Israel.”

Bitachon is one of the most elusive concepts in Judaism. In today’s society, people confuse religious dress and ritual adherence with faith; however, faith in the G-d of Israel is not measured in such ways. True belief in G-d must reside in the heart of a Jew. One does not build faith by studying only Talmud, but also by doing good deeds and following the commandments of the Torah.

David Hamelech showed bitachon when he went out to battle Goliath. As a child, it is obvious that he did not have the talmudic knowledge that many Rabbinical leaders have today, but his faith in the one and only G-d empowered him to conquer his fear and defeat Goliath. From this we learn that faith in G-d is independent of intellectual prowess.

Our leader, Rabbi Meir Kahane (Z’tl), taught us that all of the troubles that plague our people in this generation—especially regarding the integrity of the land of Israel—can only be surmounted by complete faith in the G-d of our forefathers and not by fearing the nations of the world or their leaders.

Bitachon is the theological and historical confidence that the Jewish people cannot be destroyed. It rests on the biblical covenant, the repeated pattern of Jewish survival against overwhelming odds (Egyptian slavery, Babylonian exile, Roman destruction, medieval expulsions, the Holocaust, and the rebirth of sovereignty in 1948), and the conviction that Jewish destiny is ultimately in the hands of Providence even while human effort remains obligatory.

This is not passive fatalism. Kahane presented Bitachon as the spiritual foundation that makes the other four principles sustainable. Without faith that the Jewish people have an eternal future, the demands of Ahavat Yisrael, the cultivation of Hadar, the readiness of Barzel, and the rigor of Mishmaat lose their ultimate meaning. With that faith, even severe setbacks become temporary, and the obligation to act remains clear.

Bitachon therefore combines religious trust with historical realism. It affirms that antisemitism is a permanent feature of the non-Jewish world yet simultaneously asserts that the Jewish people will outlast every enemy. The Land of Israel and the Torah are presented as central to that indestructibility. Faith in G-d is not a substitute for action; it is the ground that makes courageous action possible and meaningful.

The Interconnection of the Five Principles

The five principles are not independent slogans. They form an integrated system:

- Ahavat Yisrael supplies the emotional and moral bond that makes every Jew responsible for every other Jew.

- Hadar supplies the psychological and cultural self-respect that allows a Jew to stand upright without apology.

- Barzel supplies the capacity for effective defense and the refusal to accept perpetual victimhood.

- Mishmaat supplies the organizational and personal discipline required for collective action and sustained struggle.

- Bitachon supplies the transcendent confidence that the Jewish people possess an eternal destiny and that no enemy can ultimately prevail.

Together they reject both assimilationist quietism and purely reactive victimhood. They demand that Jews regard themselves as a proud, responsible, capable, and eternal people who must take primary responsibility for their own security and dignity. This was the ideological foundation Kahane gave the Jewish Defense League in 1968, and it continues to be presented by those who invoke the JDL tradition as the framework for Jewish self-assertion in every generation.

These principles remain as relevant today as they were in 1968. They call upon every Jew to love the Jewish people without reservation, to take pride in Jewish identity without apology, to cultivate strength without hesitation, to practice discipline without fragmentation, and to maintain unbreakable faith in the indestructibility of the Jewish people and the G-d of Israel.
