Rethinking Israel’s Military Doctrine

The October 7 attacks exposed more than an intelligence lapse; they challenged the assumptions underpinning Israel’s modern defense strategy. The country’s emphasis on border fortifications, missile defenses, and rapid mobilization has delivered formidable tactical capabilities but has also left Israel largely reactive to threats orchestrated by regional adversaries. Israel should complement territorial defense with a limited expeditionary capability capable of disrupting hostile networks beyond its borders. Yet such a transformation would require not only new military structures but also political restraint, stronger logistical capacity, and a clear understanding of the risks inherent in projecting power. The debate is therefore less about creating an offensive military than about redefining deterrence in a region where threats increasingly originate far from Israel’s frontiers.

Wars often expose not merely tactical shortcomings but conceptual ones. The October 7 attacks did both. Israel’s intelligence failures have been extensively scrutinized. Less attention has been paid to the strategic assumptions that allowed those failures to prove so consequential.

For decades, Israel’s defense posture has rested on an increasingly familiar formula: strengthen the border, improve surveillance, intercept incoming attacks, and mobilize overwhelming force once deterrence fails. The approach has produced remarkable technological sophistication. It has also left Israel responding to threats largely on terms chosen by its adversaries.

The result is a paradox. Israel possesses one of the world’s most capable militaries, yet it increasingly finds itself fighting defensively. Missile-defense systems blunt attacks but cannot prevent them. Border barriers complicate infiltration but cannot eliminate it. Air power inflicts heavy costs but rarely alters the strategic environment on its own.

This is the logic of the fortress: formidable, resilient—and fundamentally reactive.

That model may have been sufficient when threats originated primarily along Israel’s immediate borders. It is less convincing in an era defined by long-range drones, precision missiles, proxy militias, cyber operations, maritime disruption, and increasingly integrated regional networks. Iran’s strategy depends precisely on dispersing military capabilities across several countries while avoiding direct confrontation. Other regional actors have also expanded their reach through naval modernization, proxy relationships, and asymmetric warfare.

The implication is uncomfortable. Israel’s adversaries have become increasingly adept at projecting power beyond their own territory, while Israel remains structured primarily to defend its own.

The proposed solution—a permanent expeditionary command capable of operating beyond Israel’s borders—deserves serious consideration, although perhaps for different reasons than its advocates suggest.

The proposal is not one of territorial expansion or prolonged occupation. Rather, it seeks to fill the gap between clandestine special operations and full-scale conventional war. Such a force would be designed to conduct limited operations against the logistical networks, maritime corridors, launch sites, and command infrastructure that enable sustained pressure against Israel.

The strategic logic is straightforward. Rather than waiting for missiles to be launched, disrupt the systems that produce and sustain them.

Whether this requires an entirely new command structure is another matter.

Modern expeditionary warfare is among the most demanding military enterprises. Success depends less on elite combat units than on logistics, transport, engineering, intelligence integration, air defense, coalition interoperability, and political discipline. These are expensive capabilities that small states often struggle to maintain, particularly when their primary security obligations remain close to home.

Supporters of the concept argue that Israel’s size strengthens rather than weakens the case. A geographically narrow country has limited tolerance for prolonged conflict on its own territory and therefore benefits from pushing military competition outward whenever possible.

The argument has merit. But it also carries risks.

History is replete with examples of limited military interventions evolving into open-ended commitments. Tactical success frequently proves easier than defining political end states or executing orderly withdrawals. Expeditionary capabilities expand strategic options, but they also increase the temptation to use them.

That places political judgment—not military capability—at the center of the debate.

The article identifies Kharg Island, Iran’s principal oil-export terminal, as a useful thought experiment. The question is not whether Israel should seize the facility. Rather, it asks whether Israel possesses the ability to isolate, temporarily secure, and then transfer control of such a strategically significant asset during a wider regional conflict.

The answer today is probably not.

Israel retains the ability to strike distant targets with considerable precision. Sustaining military operations far from home, protecting supply lines, integrating naval and air assets, and managing coalition operations represent a different level of military complexity. The gap illustrates the difference between destroying infrastructure and shaping the political consequences that follow.

The same logic extends to the Eastern Mediterranean. Israel’s growing security relationships with Greece and Cyprus reflect an increasingly shared interest in maritime security and regional stability. Yet partnerships become strategically meaningful only when they are backed by credible operational capabilities rather than diplomatic declarations alone.

Even so, military innovation cannot substitute for strategic clarity.

The greatest lesson of October 7 may not be that Israel requires a new military command, but that deterrence itself has become more complicated. Modern conflicts increasingly blur the distinction between front lines and rear areas, military and civilian infrastructure, state and non-state actors. Defensive technologies remain indispensable, but they rarely determine political outcomes by themselves.

Nor should policymakers assume that greater operational reach automatically produces greater security. Expeditionary forces create opportunities to shape events beyond national borders, but they also introduce new vulnerabilities, financial costs, and escalation risks. Every increase in military flexibility carries corresponding political obligations.

Israel therefore faces a broader strategic question than organizational reform alone can answer. Should its future security continue to rely primarily on defending its borders, or should it place greater emphasis on disrupting threats before they mature? The answer is unlikely to lie exclusively in either approach.

The region’s security environment has undoubtedly changed. The institutions designed to manage it must evolve accordingly. But successful adaptation requires more than new commands or new platforms. It requires a coherent doctrine that balances operational reach with political restraint, military innovation with strategic discipline, and tactical success with long-term regional stability.

That debate is only beginning.
