What Drives Israel’s Aggressive War Strategy? How History Still Shapes Its Military

Israel’s strategic mindset can be traced back to its creation in 1948, when it fought the Arab-Israeli war. Surrounded by hostile neighbours, Israel faced constant existential risk

When Israeli forces struck more than 100 targets in Lebanon within minutes on April 8, it underscored the scale and intensity that has come to define its military operations. The strike drew comparisons with earlier escalations in the region, including the Gaza conflict of 2023, which saw heavy casualties and a rapid cycle of retaliation.

Israel is widely regarded as one of the world’s most capable and battle-tested militaries, frequently at the centre of global security debates. It has repeatedly confronted threats from groups such as Hamas and Hezbollah, as well as tensions involving Iran.

But what explains the intensity of its response, and why does its strategy often rely on overwhelming force?

A State Born In Conflict

Israel’s strategic mindset can be traced back to its founding in 1948, when it was immediately drawn into the Arab-Israeli War. Surrounded by hostile neighbours and lacking both territorial depth and population size, the young state developed a constant awareness of existential risk.

According to historian Yaron Peleg, as quoted by The Conversation, Israel’s hardline military approach can be traced back to the early days of Zionism in the 19th century. Many Jews who arrived in Palestine were fleeing deep-rooted anti-Semitism in Europe, and in response, there was a growing emphasis on strength, self-defence and reclaiming a sense of dignity, often inspired by Biblical Jewish heroes.

This early insecurity shaped a doctrine centred on survival. Unlike larger nations, Israel could not afford prolonged wars or repeated losses. Its leadership came to view every conflict as potentially decisive, reinforcing a security-first approach that continues to define its military thinking.

What Is The Key Element Of The Israeli Military Strategy?

One of the most defining elements of Israeli strategy is the willingness to strike first when a threat is perceived as imminent. This approach is rooted in the belief that waiting can be dangerous in a volatile region.

Israel’s military strategy has long been built around three core principles– deterrence, early warning and the ability to secure a swift, decisive victory — shaped largely by its limited geographic depth and constant security pressures.

In practice, this has meant relying on pre-emptive strikes, maintaining strong air superiority and carrying out what is often described as a “campaign between wars," aimed at weakening adversaries before full-scale conflict breaks out.

The Six-Day War remains the clearest example. Israel launched a pre-emptive airstrike against Arab states, primarily Egypt, Jordan and Syria that crippled opposing air forces within hours, secured victory by capturing the Sinai Peninsula, Gaza Strip, West Bank, East Jerusalem, and Golan Heights.

In recent years, the strategy has evolved to include stronger ground operations and growing cyber capabilities. At the same time, it has drawn criticism for its use of overwhelming force in certain conflicts, often associated with what is referred to as the Dahiya doctrine.

The Dahiya Concept And The Gospel

The so-called “Dahiya Doctrine" takes its name from Beirut’s Dahiya neighbourhood, which Israel targeted heavily during the 2006 Lebanon war, identifying it as a stronghold of Hezbollah. The scale of destruction there later came to define a broader approach, using overwhelming force against infrastructure and civilian areas to send a strong deterrent message.

At its core, the doctrine is rooted in deterrence — the idea that imposing severe costs can discourage future attacks. Israeli strategy has long relied on this principle, combining technological superiority with swift, high-intensity operations to signal consequences to adversaries.

Over time, this approach has evolved with technology. Recent reports suggest the use of AI-assisted systems, such as target-generation tools, to identify and prioritise strike locations at a much faster pace than before. These systems can expand the scope and speed of operations, particularly in densely populated conflict zones like Gaza.

However, the doctrine remains deeply contested. Critics argue that such tactics risk disproportionate damage to civilian infrastructure and raise serious humanitarian concerns. Supporters, on the other hand, view it as an extension of Israel’s long-standing deterrence strategy in an increasingly complex security environment.

Despite its intent, the effectiveness of this approach in preventing future conflict remains widely debated.

Why Israeli Wars Are Have Speed And Overwhelming Force

Israel’s military doctrine has traditionally been built around the idea of fighting short, decisive wars. Given its limited geography and resources, the aim was to secure rapid victories, often through early air dominance and overwhelming force, before conflicts could stretch into prolonged battles. The Six-Day War remains a defining example of this approach.

However, the nature of conflict has shifted in recent years, particularly since late 2023. Instead of brief, high-intensity operations, Israel is now facing more prolonged, multi-front engagements that place sustained pressure on both its security apparatus and economy.

A key reason for this shift is the rise of non-state actors such as Hamas and Hezbollah. Unlike conventional armies, these groups operate within urban environments, making it far more difficult to achieve quick, decisive outcomes and often extending the duration of conflicts.

In the periods between major wars, Israel has also followed a strategy often described as “mowing the grass" — conducting periodic, limited operations to weaken adversaries rather than seeking a final, lasting resolution, particularly in Gaza.

How Israel Uses Deterrence Through Force

Another cornerstone of Israeli doctrine is deterrence. The idea is to prevent future attacks by demonstrating that any aggression will be met with a significantly stronger response.

This approach, often described as deterrence by punishment, has shaped Israel’s responses in conflicts involving groups like Hamas and Hezbollah. The goal is not only to neutralise immediate threats but also to impose long-term costs that discourage further hostility.

However, this strategy often draws criticism, particularly when it results in extensive damage in densely populated areas.

What Are The Criticisms Against Israel’s Strategy?

Israel’s military actions often sit at the centre of intense global debate. Critics argue that its use of overwhelming force leads to disproportionate civilian harm and raises serious concerns under international humanitarian law.

Supporters counter that Israel faces unique security challenges and must operate in an environment where its adversaries do not follow conventional rules of warfare. They argue that its doctrine is a response to persistent threats rather than an arbitrary choice.

This tension between military necessity and humanitarian concerns remains unresolved and continues to shape international opinion.

Why Western Allies Continue To Support Israel

Despite criticism, many Western countries, particularly the US, continue to support Israel. This backing is driven by a combination of strategic, political and historical factors.

Israel is seen as a key ally in a volatile region, with strong intelligence-sharing networks and technological cooperation. At the same time, Western governments often emphasise Israel’s right to defend itself against armed groups.

However, this support is increasingly accompanied by calls for restraint, reflecting growing pressure from global public opinion.

A Doctrine Shaped By History

Israel’s way of war is not simply about tactics, it is the product of historical experience. From its founding conflicts to modern-day asymmetric warfare, each phase has reinforced a doctrine built on speed, pre-emption and deterrence.

Understanding this context is essential to interpreting current events. It explains why Israel often acts quickly, why it prioritises overwhelming force and why its actions provoke both support and criticism.

In a region where past wars continue to shape present decisions, Israel’s military strategy remains deeply tied to its history, and that history continues to influence how conflicts unfold today.
