Iran’s resilience during its recent four-month conflict against Israel and the United States highlights a shift in modern warfare, proving that a middle power can sustain its regime and industrial output despite intense external pressure. According to UNSW Sydney professor David Kilcullen, the conflict demonstrates how decentralized command structures, proxy networks, and “mosaic defense” strategies allow nations to maintain control even when facing superior military forces. These developments suggest that traditional military hierarchies may be increasingly vulnerable to asymmetric tactics.
How does unconventional deterrence work in modern conflict?
Unconventional deterrence relies on the strategic use of proxy networks to create costs for an adversary that exceed the benefits of a direct attack. As Kilcullen notes, Iran’s “axis of resistance”—comprising groups like the Houthis, Hezbollah, and Hamas—provided the regime with strategic depth for decades. By threatening to sabotage infrastructure or strike bases, these proxies forced adversaries to calculate the potential for regional escalation before acting. While Australia maintains different ethical and legal standards, Kilcullen suggests that adopting similar irregular warfare capabilities, such as small, amphibious teams or undersea drone swarms, could similarly influence an adversary’s decision-making process.
The “mosaic defense” strategy allows a military to remain operational even if central leadership is neutralized. By delegating authority to 31 regional commanders, Iran ensured its forces could continue to strike pre-identified targets without waiting for orders from Tehran.
Why is intra-war deterrence critical for national survival?
Deterrence is not merely a pre-war strategy; it must function throughout the duration of a conflict to limit an enemy’s actions. Intra-war deterrence involves using specific assets—such as mines or precision drones—to force an opponent to change their tactical behavior. Kilcullen points to Iran’s use of mines to keep US naval vessels out of the Persian Gulf as a primary example. For Australia, this underscores the necessity of maintaining the ability to deny an enemy their objectives even after hostilities have commenced, potentially preventing the use of certain weapons or specific strikes on sovereign territory.
How can regional relationships act as a buffer during war?
Regional diplomacy serves as a secondary line of defense when formal military alliances are tested. Despite Iran’s aggressive posturing toward its neighbors, its diplomatic engagement with Pakistan and Oman facilitated negotiations that helped restrain the conflict. Furthermore, Iran successfully pressured regional countries to deny the US and Israel access to their bases or airspace. For a middle power like Australia, Kilcullen argues that regional relationships are often overlooked assets that can provide critical support, mediation, and logistical denial during a time of crisis.
To improve national resilience, focus on “magazine depth.” This means stockpiling low-cost, mass-produced drones and missiles rather than relying exclusively on a small number of high-tech, expensive platforms that are difficult to replace during a prolonged conflict.
What lessons exist for decentralized defense and industry?
Centralized command structures are often the first targets in modern air campaigns, making decentralization a necessity for survival. Iran’s ability to continue missile and drone production from concealed, dispersed facilities proved that a decentralized industrial base is harder to destroy than large, centralized factories. Australia currently favors a central command model based in Canberra and Bungendore, which is effective for expeditionary operations but may lack the resilience required for a major conflict on Australian soil. Kilcullen advocates for a return to World War II-era thinking: stockpiling critical components and integrating dual-use facilities into the national defense infrastructure.
Frequently Asked Questions
What is “mosaic defense”?
It is a military strategy where authority is delegated to regional commanders, allowing them to operate independently if central command is destroyed. This prevents the “decapitation” of a military force.
Why does “magazine depth” matter?
Magazine depth refers to the quantity of munitions a country has on hand. In modern warfare, the ability to sustain high-volume fire with low-cost, rapidly manufactured weapons is often more decisive than having a few high-tech, irreplaceable systems.
How does Australia’s defense strategy differ from Iran’s?
Australia maintains a high-tech military with advanced capabilities but limited capacity, focusing on expeditionary roles. In contrast, Iran utilizes a large mobilization base and a decentralized industrial model to endure sustained conflict, a shift Kilcullen suggests Australia may need to emulate.
