“You can’t stop the predator from attacking — but you can make sure it regrets doing so.”
In an era dominated by great-power rivalries, smaller states often face the daunting challenge of defending themselves against larger, better-equipped adversaries. The Porcupine Strategy has evolved into a logical and resilient method for deterrence and defence. It is named after the rodent whose sharp quills deter its predators. The strategy aims not to subjugate an aggressor, but to make invasion costly, protracted, and untenable. It is rooted in the principles of asymmetric warfare, adaptability, decentralisation, and resilience.
Origins. The term “porcupine strategy” entered the military lexicon through William S. Murray (a professor at the U.S. Naval War College) in 2008. It gained prominence in discussions of Taiwan’s defence policy, as the island faced mounting pressure from mainland China. However, the underlying logic of the approach (making oneself too difficult or costly to conquer) has historical precedents. Israel’s layered defences during the 1973 Yom Kippur War, and Finland’s “motti” tactics against the Soviet Union in the 1939–1940 are historical examples of a similar approach.
Conceptual Foundation. The Porcupine Strategy is built on a simple proposition: when direct confrontation is unwinnable, deterrence by denial becomes the best form of defence. Instead of trying to match a superior enemy tank-for-tank or jet-for-jet, the defender focuses on capabilities that exploit the attacker’s weaknesses—such as mobility, supply lines, and overextension. Murray formalised these ideas into a cohesive doctrine. The doctrine was for island defence (Taiwan). He theorised the concept on three pillars. These pillars are access denial, survivability through dispersion, and cost imposition.
Key Principles
The effectiveness of the Porcupine Strategy lies in its adherence to a set of interconnecting principles. These principles include asymmetry, decentralisation, resilience, and civil-military integration.
Asymmetry. Asymmetric defence recognises that smaller nations cannot win through conventional parity. Instead, they focus on low-cost, high-impact weapons and tactics. Portable anti-tank and anti-air missiles, drone swarms, and coastal defence systems are typical tools. By investing in thousands of relatively inexpensive weapons rather than a few large platforms like battleships or fighter squadrons, the defender can sustain resistance and impose continuous attrition on an invading force.
Decentralisation. Traditional militaries often depend on centralised command and control structures that can be disrupted early in a conflict. The Porcupine Strategy, by contrast, decentralises decision-making and operations. Small, autonomous units can continue fighting even if the national command structure is compromised. This approach ensures continuity of resistance. It also complicates the invader’s ability to deliver a knockout blow.
Resilience and Denial. A porcupine cannot stop a predator from attacking, but it can ensure that the experience is painful enough to deter the predator. Similarly, the Porcupine Strategy aims to deter the enemy rather than achieve a decisive victory over him. According to this concept, the defence plans rely on mobility, concealment, and attrition. The enablers of the sustained resistance include hardened infrastructure, stockpiles of ammunition, and redundant logistics networks.
Civil-Military Integration. The strategy necessitates integration of the civilian population into national defence planning. This includes reserve forces, civil defence training, cyber defence volunteers, and information resilience programs. Civilian involvement not only increases manpower and situational awareness but also reinforces national willpower—one of the most critical elements in enduring protracted conflict. In this model, every citizen becomes part of a “whole-of-society defence.”
Case Study: Taiwan’s Porcupine Strategy
Nowhere is the Porcupine Strategy more relevant today than in Taiwan, whose geographic proximity to China and democratic identity make it a potential flashpoint in global security. Facing the possibility of a large-scale amphibious invasion or blockade, Taiwan has increasingly embraced an asymmetric defence posture.
The U.S. and allied analysts have urged Taiwan to shift its focus away from high-value, easily targeted platforms—such as advanced fighter jets and large naval vessels—and toward mobile, survivable, and cost-effective systems. These include:-
Anti-ship and coastal defence missiles (e.g., Harpoon and Hsiung Feng systems)
Mobile air defence units using Stinger or Sky Sword systems
Mines and unmanned aerial vehicles for area denial
Rapidly deployable infantry and special forces for urban and guerrilla warfare
By dispersing its forces and relying on mobility rather than fixed installations, Taiwan seeks to make a full-scale invasion prohibitively difficult. Even if initial landings succeed, occupation and consolidation would face sustained resistance, both military and civilian.
Comparative Examples
Ukraine. After 2014, Ukraine’s military reforms incorporated many elements of the Porcupine theory. The country invested heavily in defensive capabilities. It also developed a strong reserve force and local defence networks. These measures played a decisive role in thwarting the initial Russian offensive in 2022. Ukraine’s experience stresses the value of distributed resistance. It also highlights the difficulty of subduing a determined population even by a superior force.
Finland. Finland’s “total defence” doctrine, developed during the Cold War, contains many aspects of the Porcupine Strategy. Finland has a strong civil defence network, with a role for every citizen in national defence. It also has an extensive reserve force and hardened infrastructure. Finland’s focus on nationwide preparedness has long served as a deterrent to potential aggressors. This approach demonstrates that the Porcupine Strategy is not limited to small island nations; it is equally applicable to continental states with strong civic cohesion.
Strategic Goals and Outcomes. The Porcupine Strategy aims to achieve four key strategic objectives. By achieving these aims, vulnerability can be easily transformed into a source of strength. The defending nation cannot match the enemy’s might, but it can erode their will and ability to achieve a decisive victory.
Deterrence by Denial. Convince the aggressor that success is unlikely and prohibitively costly.
Attrition and Delay. Force the attacker to expend vast resources for limited territorial gains.
Survivability. Ensure the defender can continue fighting even under severe attack.
Psychological Impact. Signal to the aggressor—and the international community—that the nation will resist to the end.
Limitations and Challenges.
The porcupine strategy is not without challenges. It requires long-term commitment, societal resilience, and political will. Stressing too much on asymmetric defence could lead to neglect of traditional military power. The opposite side could get emboldened by it. Additionally, external assistance is crucial for the strategy’s success. Assistance is required in the form of intelligence sharing, arms supply, and diplomatic support. In the absence of external support, even an exceptionally well-designed plan can become ineffective over time.
Conclusion
“Survival often depends not on outmatching the enemy, but on outsmarting them”.
In today’s world, military power is unevenly distributed. The Porcupine Strategy endorses that strength does not always lie in size. It is also dependent upon the ability to endure, resist, and make aggression costly to pursue. The Porcupine Strategy transforms vulnerability into deterrence. It is one of the adaptive and realistic defence doctrines for small and medium-sized states.

Bagram airbase is situated about 50 kilometers north of Kabul in Afghanistan’s Parwan Province. The fortified base has two runways and a vast support infrastructure. It has been a nerve center for every significant foreign military power to occupy the country since the Cold War. It was constructed in the 1950s and expanded significantly during the Soviet era. It became the main hub for Soviet military operations in Afghanistan during their 1979–1989 occupation.
Following the events of 9/11, the airfield was transformed into the centerpiece of the U.S.-led coalition’s operations in Afghanistan. At its peak, the facility featured runways capable of handling large transport and bomber aircraft, more than one hundred revetments, massive logistical and support infrastructures, and housed thousands of troops and aircraft. It was the launchpad for drone strikes, intelligence missions, and air support operations.
On 2 July 2021, after almost twenty years of continuous U.S. control of Bagram Airfield, the control was handed over to the Afghan authorities, marking a key moment in the coalition’s withdrawal from Afghanistan. Bagram became a symbol of the chaotic U.S. withdrawal from Afghanistan.
Four years later, the airbase has again attracted global attention. But this time, the debate isn’t about counterterrorism. It’s about geopolitical competition, regional sovereignty, and a changing balance of power in Asia.
A Strategic Asset. Bagram’s strategic appeal is noticeable. Located less than an hour’s flight from China’s western Xinjiang province and within reach of Iran, Pakistan, and Central Asia, it offers unparalleled access to some of the most contested airspace in the world. The base has two runways capable of hosting heavy bombers and long-range reconnaissance aircraft, along with hardened hangars, and infrastructure enough to house thousands of personnel. For the United States, regaining access to such a facility could restore a foothold in Central Asia. The region is now dominated by Chinese and Russian influence. For the Taliban, retaining control over it is both a matter of pride and sovereignty. For neighbouring countries, Bagram represents a potential spark that could reignite competition and instability.
Bagram’s Symbolic Power. Besides military significance, Bagram airbase has become a symbolic battlefield in the narrative wars. For the Taliban, it is a monument to victory. It symbolises foreign retreat and the restoration of national control. Military parades featuring captured U.S. hardware have been staged there annually since 2022, turning the base into both a propaganda tool and a training hub. For Western observers, Bagram remains a haunting reminder of how two decades of war ended with little enduring infrastructure or political legacy.
Renewed US Interest. In September 2025, former U.S. President Donald Trump reignited the debate over Bagram by declaring that the U.S. is “trying to get it back.” Trump, while speaking at a joint press conference (with UK Prime Minister Keir Starmer), contended that the vital airbase was “given up for nothing”. His subsequent post on his social media escalated the rhetoric. He claimed that the base needs to be reclaimed. Otherwise, the “enemies of freedom” would consolidate power across the region. The Taliban called these comments delusional. Afghanistan spokesperson Zabihullah Mujahid stated that Bagram belongs to Afghanistan and not a meter of our land will return to foreign occupation.” However, the US president’s statement rekindled speculation about Washington’s interest in regaining influence in Afghanistan. Analysts feel that any U.S. attempt to retake the base would be an undertaking politically and strategically implausible in the current climate.
The Regional Chessboard. Bagram’s fate is not just a bilateral issue between Washington and Kabul. It sits at the intersection of larger geopolitical currents.
China views any U.S. return as a potential surveillance threat to its Belt and Road investments and its sensitive Xinjiang region.
Russia, seeking to expand its influence across Central Asia, has made clear that it will not tolerate new Western military outposts in the region.
Iran shares similar concerns and has strengthened its ties with the Taliban, providing limited economic and diplomatic backing.
Pakistan is caught between its complex relationship with the Taliban and with Washington.
For India, interest in the airbase is governed by factors such as location & connectivity, regional competition, and Afghanistan’s sovereignty & stability.
Regional Powers Push Back. The strongest rebuke came from Afghanistan’s neighbours. On October 7–8, 2025 (at the 7thMoscow Format Consultations on Afghanistan), Russia, China, Iran, India, Pakistan, and the Central Asian republics issued a joint declaration. They collectively rejected the idea of any foreign military presence on Afghan soil. The statement was obviously directed at Trump’s remarks and potential U.S. ambitions. The declaration reflected a fear about upsetting the stability in Afghanistan. Moscow and Beijing view any American return as a strategic encroachment. Islamabad is concerned about the growing influence of domestic insurgents. India publicly supported Afghanistan’s sovereignty and rejected the idea of foreign bases. Indian officials emphasised the need for “regional solutions” over external interventions.
Disinformation Drive. Rumours of U.S. (even Indian) control of Bagram airbase are circulating online. A social media post purported that the Taliban had transferred limited control of Bagram to US Special Forces. The report was debunked by both Taliban and U.S. officials. Similar speculation suggested that India might be using the base. The Afghan Foreign Ministry dismissed the rumours as a disinformation campaign and reaffirmed that there is no foreign presence.
Firm Taliban Control. All official reports indicate that Bagram Airbase is firmly under Taliban control. No confirmed signs of U.S., Indian, or any other foreign presence have emerged. In official statements, Taliban leaders have pledged to maintain the base for Afghanistan’s defence forces and reject “any form of shared control.” This stance enjoys regional support, even among nations that remain wary of Taliban governance.
Spotlight Remains. The Bagram issue captures the Afghan post-war era dilemma. It is a clash between its sovereignty and strategic interest. The airbase has become a measuring stick for regional order. As of now, no U.S. re-involvement appears imminent. But the rhetoric surrounding Bagram indicates how Afghanistan continues to serve as both a symbol and a stage in the contest for influence between the world powers (Washington, Beijing, and Moscow). For Afghans, it also serves as a reminder that even during a supposed state of peace, the fight for control in Afghanistan is not yet over.
