You shall lay siege to the city that is waging war against you until it is subdued.

DEUTERONOMY 20:20

A hallmark of Israel’s wars is that they appear to go in cycles, or “rounds,” as the Israeli idiom has it. Israel has fought war after war in Gaza and in Lebanon (and the same observation can be extended to Israel’s wars with Iran). Beyond proactive defense, how might we end the cycle of violence and make peace? The answer is simple. Instead of engaging in timid, piecemeal, responses, a Jewish army must fully neutralize threats.

Halachic Foundations

The Torah teaches,1 “You shall lay siege to the city that is waging war against you until it is subdued.” Shammai, a Mishnaic Sage, interprets the verse, “until it is subdued,” as a directive to continue fighting until the enemy surrenders.2 Maimonides codifies this as normative Jewish practice.3

The Rebbe’s Critique of Israeli Military Strategy

The word “subdued” means that the enemy must be brought to a point where it can no longer fight, no longer poses a threat, and will not pose a threat in the future.4 Therefore, the Rebbe vocally critiqued the Israeli government’s tendency to engage in limited military operations rather than pursuing conclusive victories. The Rebbe called for a decisive approach: once engaged in conflict, it is crucial to persist until the enemy is subdued. This is more than just strategic; it is a moral and religious imperative to avoid prolonged conflict and additional loss of life.

Practical Implications of “Until It Is Subdued”

The Rebbe explained that this principle has far-reaching implications for a broad range of military objectives and security policies. Furthermore, mere adoption of this doctrine as a perspective positively impacts Israel’s ability to win wars and protect the lives of its soldiers and its people.

1. The Ethics of Warfare

The Rebbe applied the idea of “until it is subdued” as a directive that gives perspective and shifts the way a Jewish army fights wars. For the Rebbe, this doctrine teaches the importance of avoiding ground operations in urban environments, as they can be costly and counterproductive. Instead, the doctrine demands siege tactics and precision airstrikes. This orientation minimizes collateral damage while disrupting terrorist groups’ operations and supply lines. It increases pressure on the enemy while lowering risks for the Jewish army. Fighting with a mindset of “until it is subdued” seeks to compel the enemy’s quick surrender, leading to a swift resolution of the conflict without the need for extensive, urban combat operations which inflict heavy costs on both sides.5

2. Ending Domestic Terrorism

Persistent terrorist attacks against Israel necessitate decisive responses. The alternative is a lenient approach that avoids prosecuting terrorists. The Rebbe firmly endorses the first option, emphasizing the necessity of neutralizing terrorists to deter future attacks. This aligns with the principle of pursuing enemies “until they are subdued.”6 A softer approach emboldens terrorists, perpetuating the cycle of violence.

Security operations must be comprehensive, eliminating threats and establishing lasting security, actualizing the biblical promise that “you will lie down [to sleep] and have no fear.”7 Scripture warns us against treating threats indecisively, stating,8 “And those [hostile people] that you allow to remain shall become stings in your eyes and thorns in your sides, and they shall harass you in the land in which you live.”

3. The Alternative: “Mowing The Grass”

The alternative to fighting an enemy “until it is subdued” is an approach referred to in works of military strategy as “containment.”9 In Israel’s conflicts with Hamas and Hezbollah, (and one can perhaps see this in Israel’s conflict with Iran) this policy had been explicitly articulated and adopted, referred to by Israeli military theorists as “mowing the grass.” This approach prescribes recurring, limited responses to persistent terrorist threats.10 It involves tactical operations aimed at temporarily crippling terrorist capabilities without fully eradicating them. It fails to offer a long-term solution for eliminating belligerents. Under containment, Israel’s diverse enemies emerged strengthened. Only decisive military action quelled the PLO, Hamas, and Hezbollah.

4. The Only Way to Honor the Memory of the Fallen

The Rebbe stresses that containment squanders resources and lives, allowing the enemy to return and inflict more damage. Conversely, fully subduing the enemy validates the expenditure of resources and honors the memory of those who perished in battle, as it paves the way to lasting peace. As the Rebbe expressed it:11

Soldiers died in order to conquer and defend these territories which are vital for national security. They laid down their lives with the simple faith that by doing so, they were defending the Land of Israel and the Children of Israel. If we give away these territories, then the Jewish soldiers who fell (each of whom is “an entire world”) made a pointless sacrifice.

This is not merely theoretical. In the course of writing Make Peace’s first edition, during the 2023 Israel-Hamas War, I was privileged to spend time with many active duty soldiers in the IDF. One soldier shared, “If we return to the status quo in Gaza after the war, I feel that all my friends who died, young men with wives and children, with dreams and aspirations, will have died in vain. And that I and my future sons will end up going back to fight in Gaza.”

The Rebbe’s call for a decisive approach has often been disregarded by Israel’s military and political leadership, as well as by many in the general public, particularly those not under direct fire themselves. The October 7 massacres led to a paradigm shift for many, with even Professor Eitan Shamir, one of the key articulators of the “mowing the grass” containment strategy, moving towards a stance more aligned with the Rebbe’s view.12 In the following case studies, we will explore the consequences of failing to neutralize threats. Then, we will explore case studies which demonstrate the doctrine’s soundness.

Case Studies: Israel’s Failure to Neutralize Military Threats

A) Compassionate Jewish Naivete: Israel and Aram

Before delving into contemporary case studies, let’s journey back 3,000 years to the ancient Kingdom of Israel.13 The biblical Book of Kings14 recounts how the Aramean king, Ben-Hadad,15 along with thirty-two allied warlords and their armies, laid siege to Samaria, the Kingdom of Israel’s capital. He sent messengers to King Ahab, the Israelite king, who proclaimed: “Your gold and silver, your women and children – are mine.” Ahab responded by offering to pay taxes to Aram, yet Ben-Hadad still threatened to invade the Kingdom of Israel and enslave its people. Encouraged by G‑d’s prophet,16 the Israelite Kingdom heroically defeated Ben-Hadad and his allies.

The prophet warned Ahab that despite Aram’s defeat on the battlefield, they would attack again the following year. Indeed, Ben-Hadad regrouped with a more formidable coalition, but once more, G‑d granted the Israelite army a victory. Ben-Hadad fled, but his advisors told him, “The Jews are a merciful people. If you surrender, they may spare your life.” Ben-Hadad’s men came to Ahab wearing sackcloth17 and begged for mercy. Overjoyed at the Arameans’ interest in peace, Ahab agreed to a peace treaty, sparing Ben-Hadad’s life.

Ahab quickly overlooked Ben-Hadad’s hostility, referring to him as “his brother” and even agreed to a trade deal with Aram. After three years of quiet, this episode of misplaced trust ended with another attack by the Aramean armies. In this battle, the Aramean forces, acting on Ben-Hadad’s orders, killed Ahab and routed the Jewish armies.

The moral of the story, says the Rebbe, is that Israel must not relent in battle until it has rendered the enemy incapable of future aggression. The Rebbe emphasizes that the Torah’s stories are not mere historical tales; they are eternal, actionable lessons that we must learn from and apply to our present reality.18 The Rebbe laments how contemporary Israel has mirrored Ahab’s naivete, failing to apply this crucial lesson of the need for decisive victory and failing to recognize naivete of “peace treaties”. It trades a clearheaded approach for a false sense of “justice.”19 This ancient story sets the stage for examining similar patterns in Israel’s more recent conflicts.

B) The Yom Kippur War: Damascus and Cairo

During the Yom Kippur War, the Rebbe advocated decisive Israeli military action, urging the IDF to capture the Syrian capital, Damascus. He argued that doing so would humble the Syrian government and send a powerful message to never again attack Israel.20 It would also serve the immediate goal of securing the northern front, allowing Israel to focus all its efforts on defeating Egypt in the south. The Rebbe suggested a similar approach to Cairo, with the aim of undermining Egypt’s military capabilities and establishing deterrence.21 Defense Minister Moshe Dayan and Chief of Staff General David Elazar echoed the recommendation to conquer Damascus.22 However, Prime Minister Golda Meir vetoed this course of action.

Commenting on her decision, the Rebbe drew a parallel to the forty years the Jewish people spent wandering in the desert – a situation that could have been avoided had it not been for their slave mentality. He noted a similar mindset in modern Israel’s surrender to Western pressures, leading to unnecessary tragic outcomes.23

Syria has posed a minimal threat to Israel since the 1973 Yom Kippur War, largely due to Israel’s aerial superiority and Syria’s internal conflicts. In 1982, during the First Lebanon War, Israel decisively defeated the Syrian Air Force in the largest air combat engagement in modern military history,24 and since 2011, Syria has been embroiled in a bloody civil war that has absorbed its resources, preoccupying it from attacking Israel. In December 2024, in large part due to Israel’s crippling of Hezbollah, the Syrian regime fell and Israel eliminated most of Syria’s military assets. Nonetheless, the Rebbe’s recommendation for a more assertive approach in Israel’s conflicts with Syria remains a broadly applicable point of reflection.

Despite Israel’s successful defense and strategic gains, which positioned it to capture Damascus and advance toward Cairo, the Yom Kippur War ended with a ceasefire. While Israel emerged tactically victorious, the Arab narrative framed the conflict as a defeat for Israel.25 This promoted a perception of Israeli vulnerability among its adversaries. The war resulted in a lingering narrative of half-measures. This was a deviation from the principle of “until it is subdued,” which, if applied, could have significantly altered the region’s geopolitical landscape in Israel’s favor. Reflecting on the war in a letter to then Chief Rabbi of the United Kingdom, Rabbi Immanuel Jakobovits, the Rebbe wrote:26

Another recent development bore out a view I expressed during the Yom Kippur War. I urged then, on the basis of halachah, to pursue the enemy [“until it is subdued”] (Deut. 20:20; and see also Num. 33:55), namely, to take Damascus – not for occupation, but to ensure that it “never” again would pose a threat. It was then also common knowledge that Soviet advisors were present there, with headquarters, etc. Only a few hours of occupation would have been sufficient to accomplish the task. But for “strange” reasons, it was not done. The results of the failure are evident, and have been particularly underscored recently by the military actions that were necessary to counter Soviet penetration.

C) The Gaza Wars

1. Years of Unrest

During British rule over the Gaza Strip (1920-1948), local Arabs grew increasingly hostile towards both Jewish immigrants and Jews who had been living in Gaza for generations. This hostility ultimately culminated in Arab riots, looting, and murder. In the aftermath of Israel’s victory in the 1948 War of Independence, Egypt seized control over Gaza, using it as a hub for Palestinians, many of whom had been displaced during the war. In 1967, Israel took control of Gaza in the Six Day War. It established Jewish towns in the region, collectively known as Gush Katif. Nonetheless, Gaza retained its (hostile) Palestinian majority. Israel granting greater autonomy to the Palestinians in 1993 in the Oslo accords only worsened matters. Between 1993 and 2005, Gaza was a center of terrorism, serving as a base for Palestinian terrorists carrying out suicide bombings and missile attacks against Israel.

2. Disengagement: More Violence

Israel’s 2005 withdrawal from Gaza, intended to reduce tensions and present Israel as a moral actor on the world stage, was followed by Hamas’ electoral victory in 2006 and the subsequent Gaza Civil War, leading to Fatah’s violent expulsion by Hamas.27 Crushing Fatah was only the beginning of Hamas’ reign of terror in Gaza. In June 2006, Gaza-based Palestinian terrorists kidnapped Israeli Corporal Gilad Shalit. Israel responded with restrained military operations. This began a local cycle of violence that eventually culminated in the October 7 massacres blowing open the powderkeg that resulted in the subsequent multifront war. Let’s take a tour through history and examine the results of failing to apply the doctrine of “until it is subdued” as it pertains to Israel’s treatment of Gaza.

3. The First Gaza War (2008-2009): Operation Cast Lead

The military operations, artillery exchanges, and border skirmishes in the Gaza withdrawal’s aftermath ultimately led to the First Gaza War, “Operation Cast Lead.”28 Following international outcry, Israel relented to a ceasefire and withdrew from Gaza, leaving it damaged but still under Hamas control. This withdrawal gave Hamas the opportunity to restock its arsenal and fortify its defenses. Meanwhile, the “international community” pledged $4.5 billion29 in aid to rebuild Gaza. Of course, the aid money was not primarily invested in the Gazan economy. Instead, it went to line the pockets of senior Hamas members and their families. Gaza’s leadership invested the rest of the money in building terror tunnels, developing or purchasing missiles, and in training a terror army to attack Israel.

4. The Second Gaza War (2012): Operation Pillar of Defense

The ceasefire following the First Gaza War was short-lived, as Hamas continued to launch rockets and build tunnels into Israel. This led to “Operation Pillar of Defense,” a week-long campaign marked by heavy missile volleys from Gaza and Israeli counter-strikes.30 The conflict ended with an internationally brokered ceasefire, bringing the violence to a temporary halt.

5. The Third Gaza War (2014): Operation Protective Edge

In 2014, the kidnapping and murder of three Israeli high school students in Judea and Samaria by Hamas terrorists prompted the IDF to arrest most of Hamas’ active militants in that region.31 Hamas retaliated with a barrage of thousands of rockets and mortars from Gaza into Israel, leading Israel to counterattack by bombing Gaza. This was followed by an Israeli ground offensive in Gaza – “Operation Protective Edge” – with the objective of dismantling Hamas’ military capabilities. Although the IDF demolished many terror tunnels and dealt a blow to Hamas’ infrastructure, they did not decisively cripple Hamas and instead withdrew from Gaza.

6. The Fourth Gaza War (2021): Operation Guardian of the Walls

On Jerusalem Day32 in 2021, Gaza-based terrorist organizations, Hamas and PIJ, fired a barrage of almost 4,400 rockets into Israel. Israel responded with airstrikes on over 1,500 terrorist targets in Gaza, including launch sites, command centers, and weapons’ caches, as well as by neutralizing hundreds of terrorists.33 However, despite this strong response, the terrorist organizations in Gaza managed to maintain their operational capabilities.34

7. An Uncertain Future

Clashes continued between Israel and Gaza, with intervals of rocket attacks and border skirmishes followed by IDF response with airstrikes. These intermittent attacks and exchanges of fire continued until October 7, 2023, when various Gazan groups raided Israel. They took 251 hostages, brutally murdered over 1,139 Israelis, and violated many of the women and girls. Israel responded with heavy airstrikes on Gaza, followed by full invasion with the objective of dismantling Hamas.

The question has now become: Will this be the final Israel-Gaza war? Does Israel possess the fortitude to take bold action and alter the status quo? Or will Israel once again fail to decisively end the cycle of violence, paving the way for future conflicts?

Although Israel has devastated Gaza, if it allows Gaza to be rebuilt under an autonomous Palestinian government, we can be certain, barring miracles, that the cycle of violence will perpetuate. To consider just how real a possibility this is, consider the following comments from a soldier who fought in the 2023 Israel-Hamas War. In early April 2024, I met up with a friend who was serving as a tank gunner. He had briefly returned from fighting in Khan Younis and was set to soon return to begin the Rafah incursion. “Sure, we devastated the place,” he said, “but there’s been no fundamental policy change. I’m going to bet that twenty years from now, there will be another Gaza war.”

Defeating Terrorists and Restoring Peace

As we have seen, the Rebbe emphasized the necessity of a decisive military approach to deter and defeat terrorist groups. This strategy demands not only military action, but also unwavering determination to confront and neutralize its adversaries, preventing attacks in the first place. But is there any precedent for such an approach? Has it proved successful elsewhere in the world?

If we consult recent military history, there are numerous examples of terrorist groups around the world conducting reigns of terror against civilian populations. These groups are often hosted by sympathetic (or terrorized) local populations. Can such groups be defeated? Let’s explore two case studies from around the world.35 Notably, both groups are “terrorist,” but neither are Islamist.

A) Peace in Sri Lanka: The Tamil Tigers

Sri Lanka endured over 25 years of civil war fueled by ethnic tensions between the Sinhalese majority and the Tamil minority. Some Tamils formed a militant group, known as the Tamil Tigers, seeking to establish an independent state. From 1983 until 2002, the Tigers engaged in terrorism and controlled significant territory in Sri Lanka’s northern and eastern regions. The Tigers were notorious for their use of suicide bombers and child soldiers, as well as for pioneering the use of women in suicide attacks.36 The Tigers were far more formidable than Hamas has ever been37 and enjoyed vast streams of international aid.38

In 2002, international mediators brokered a ceasefire, leading to a temporary halt in hostilities. However, several rounds of peace talks failed to produce a lasting agreement. The ceasefire collapsed in 2006, leading to renewed heavy fighting. In response, the Sri Lankan government launched a massive military offensive against the Tigers, successfully recapturing its territory. This time, despite appeals from the international community and the Tigers for ceasefires, the Sri Lankan government did not budge.39 The conflict culminated with the Sri Lankan military defeating the Tigers decisively in 2009.40 Since then, the once fierce Tigers have ceased to exist, no longer terrorizing the Sri Lankan population.

B) Ending Gang Violence in El Salvador

To further prove the point that the Torah’s doctrine of fully neutralizing threats can be effective in real world scenarios, let’s consider another example. This case study, along with the tale of the Tigers, shows that these principles are effective against domestic terrorism across ethnic and cultural lines. In recent years, El Salvador has experienced a victory in its battle against gang violence, primarily driven by President Nayib Bukele’s aggressive tactics to combat violent gangs like MS-1341 and Barrio 18.42

Before Bukele’s presidency, El Salvador grappled with one of the world’s highest homicide rates, largely due to gang violence. The gangs were deeply rooted in Salvadoran society, committing extortion, drug trafficking, and brutal violence. The government’s previous efforts, including the “Gang Truce of 2012,”43 failed to lower the murder rates.

Upon assuming office in 2019, Bukele launched a forceful and comprehensive initiative to address gang violence. His approach, known as the “Territorial Control Plan,” placed enhanced law enforcement and military intervention in gang-dominated areas. The plan culminated in the establishment of the “Terrorism Confinement Center” and the arrest of over 71,000 suspected gang members. This unyielding approach resulted in a significant drop in homicide rates and weakened the gangs’ influence.44

Securing Stability:National Security Overrides External Pressure

Both Sri Lanka and El Salvador faced condemnation from the “international community” – including the U.N.45 and media outlets like Al Jazeera – for their seemingly aggressive strategies. However, by prioritizing national security over external pressures, both nations successfully achieved peace and improved public safety. These examples suggest that if Israel consistently adopted similar tactics against terrorist threats,46 it could create a more tranquil and stable environment, allowing both sides of the conflict to lead peaceful, productive lives.

Conclusion

Military strength and strategy, while important, are not the ultimate keys to winning a war – G‑d ultimately grants victories.47 On the other hand, G‑d created a natural world and wants us to operate within its principles. As such, we must strike a balance between faith and practical action.

We see that the only way to end the cycle of violence is decisive military action. Ideally, this should be accomplished through military deterrence, stopping the battle before it starts. This deterrence should stem from a formidable military force and the perception that Israel will use it unqualifiedly if provoked. If faced with the possibility of a real threat, Israel must preemptively neutralize it. Finally if Israel is attacked, it must retaliate until the enemy has been neutralized and cannot regroup to fight another day. While other paths may appear more benevolent, they perpetuate the cycle of conflict. We must end the cycle and make peace.
