Abstract

A comparison of Malta and Palau confirms that indigenous military power and sovereign capacity in the security domain are not the same thing. Despite its low military score, Malta retains its own armed forces, constitutional neutrality, and the right to participate selectively in European cooperation. Palau delegates a substantially broader range of defense functions to the United States and receives external deterrence, strategic significance, and long-term support in return, but pays for these benefits by limiting its choice of military partners.

The aggregate index scores—480.5 for Malta and 374.3 for Palau—show a difference in the resource base, but by themselves they do not answer the central question: who determines the terms of security, and can those terms be changed without losing vital functions? The central conclusion is that delegation strengthens emergent sovereignty only when it is legally bounded, functionally diversified, supported by domestic capabilities, and subject to a practically feasible course correction.

Research Problem

Traditional approaches tend to associate sovereignty with the state’s monopoly over military resources. Small states, however, are rarely capable of independently reproducing the full defense cycle—from intelligence and airspace control to cyber defense, maritime surveillance, and strategic deterrence. Analytically, therefore, what matters is not external dependence as such, but the architecture through which authority, risk, and decision-making rights are distributed.

Malta and Palau represent two different types of delegation. Malta retains a domestic security core while supplementing it with EU capabilities and international cooperation; under the Compact of Free Association, Palau has transferred defense authority and responsibility to the United States. The first case produces a model of selective cooperative delegation; the second, a compact-based model of strategic patronage.

The research question is therefore: under what conditions does transferring security functions to an external actor expand a state’s room for choice, and under what conditions does the protection received become a channel of structural control?

Data and Method

The quantitative analysis is based on the supplied seven-dimensional profiles. Each score is treated as a resource precondition rather than as a ready-made measure of emergent sovereignty.

Malta scores higher than Palau in six of the seven dimensions, with the largest gap in the technological profile—27.8 points. Palau’s only advantage is in the military dimension, by 7 points. This inversion is especially significant: a country that has delegated broad defense responsibility to the United States receives a higher military score than neutral Malta, which maintains its own armed forces. The score may therefore reflect not only domestic assets but also access to an external security system.

The qualitative analysis uses seven mechanisms: Conversion Sovereignty, Dependence Architecture Sovereignty, Alternative Sovereignty, Reversibility Sovereignty, Boundary Sovereignty, Second-Order Sovereignty, and Reproductive Sovereignty. They are treated as a causal chain: resource → delegated function → dependence architecture → alternatives → reversibility → boundaries → influence over rules → reproduction of capacity.

Security Architectures

Malta: Cooperation Without Alliance

The Constitution defines Malta as a neutral state pursuing a policy of nonalignment and declining participation in military alliances. It prohibits foreign military bases, while permitting foreign forces to use facilities at the government’s request for self-defense, in the event of a threat to sovereignty and territorial integrity, or in implementation of decisions of the UN Security Council.

EU accession did not remove this boundary. In its declaration on neutrality, Malta affirmed its participation in the EU’s Common Foreign and Security Policy while stipulating that such participation must not prejudice its neutral status. Malta does not participate in PESCO, although participation is voluntary, and the country has not ruled out changing its position in the future.

The Maltese system therefore cannot be described as full delegation of defense. The state retains its own operational core and a political-legal filter, while using external cooperation to expand capabilities it lacks. What is delegated or jointly produced is not the ultimate decision to use force, but specific capabilities: information sharing, maritime-security coordination, cyber resilience, training, and access to EU-wide instruments.

Palau: Defense Through the Compact

The Compact of Free Association provides that the United States has full responsibility and authority for Palau’s security and defense. Palau’s territory is closed to the armed forces of other states except the United States and forces invited by the United States under its control; the United States also receives military operating rights and the ability to establish defense facilities.

These provisions exhibit substantial institutional inertia. According to the GAO, defense-site rights and key security provisions remain in force through 2044 even in the event of unilateral termination of the Compact; the strategic-denial regime applies through 2044 and thereafter until modified by mutual agreement.

At the same time, delegation does not eliminate constitutional control. Palau’s Constitution permits the transfer of major governmental powers, including defense, security, and foreign affairs, only with the approval of at least two-thirds of each house of the legislature and a majority of voters in a nationwide referendum. Agreements involving certain categories of weapons are subject to a higher threshold of three-fourths of the votes cast in a referendum.

Seven Mechanisms

Conversion Sovereignty

Malta: a limited stock of military resources is converted into capacity through a combination of neutrality, domestic coastal and territorial functions, EU membership, and international cooperation. The conversion asset is not the size of the armed forces but legal control over access: foreign forces may use infrastructure only under conditions established by the Constitution and by government decision.

Malta’s technological and informational resources are likewise converted into security capacity. The National Cybersecurity Strategy integrates governance, cyber defense, capabilities, and international cooperation, while NIS2 implementation and participation in Locked Shields exercises expand functionality without requiring a large military apparatus.

Palau: the principal conversion resource is geostrategic location. Palau grants the United States access and a strategic-denial regime and receives external deterrence, assistance, and access to security infrastructure in return. International partners also help convert Palau’s ocean territory into monitoring capacity: Australia supports aerial surveillance and efforts to combat illegal fishing in Palau’s exclusive economic zone.

The difference lies in the direction of conversion. Malta converts institutional and cognitive resources into domestically controlled cooperation; Palau converts territory and strategic value into an external guarantee. The first model is procedurally more autonomous; the second is potentially stronger as a deterrent.

Dependence Architecture Sovereignty

Malta distributes functions among national institutions, the EU, the UN, and bilateral cooperation. No external partner formally holds exclusive responsibility for its defense. Even energy security is built through a combination of domestic generation, interconnection with Italy, a planned second interconnector, storage, and renewable sources; the N−1 criterion is applied, requiring continuity of supply if the system’s largest component fails.

Palau diversifies assistance and nonmilitary functions among the United States, Japan, Australia, and Taiwan, but the defense core remains an American monopoly. Japan explicitly views coordination with the United States, Australia, and Taiwan as a means of increasing the effectiveness of assistance to Palau. The architecture is thus diversified at the periphery but concentrated at the strategic center.

The fiscal dimension reinforces the asymmetry: the IMF notes Palau’s dependence on tourism, imports, and external grants, while more than half of public spending relies on foreign assistance, primarily from the United States. Defense and budgetary dependencies therefore partly correlate, reducing the ability of one external relationship to hedge another.

Alternative Sovereignty

Malta has several ways to obtain the functional equivalent of security: its own forces, EU structures, bilateral cooperation, UN mechanisms, and the diplomatic capital of a neutral mediator. Rejecting a particular instrument—for example, remaining outside PESCO—does not terminate the other security circuits.

Palau’s alternatives are uneven. In maritime surveillance, development, and climate policy, the state works with Australia, Japan, Taiwan, and multilateral organizations. In strategic defense, however, the Compact precludes fully replacing the United States with another partner without a fundamental redesign of the entire arrangement.

This is where the distinction between having multiple partners and possessing a strategic alternative becomes clear. Palau has a portfolio of partners but not a portfolio of defense guarantors; Malta has no single guarantor but retains several partial functional alternatives.

Reversibility Sovereignty

Malta’s reversibility is relatively high at the level of individual programs: the state can join particular formats or remain outside them while retaining EU membership and its national security core. A wholesale change of course, however, is constrained by economic, energy, and regulatory integration with the EU; dependence on the European market and Italian interconnectors makes abrupt exit costly.

Palau has a legal possibility of revision, but material reversibility is low. Even unilateral termination of the Compact does not immediately end certain U.S. defense rights, while constructing an alternative deterrence system would require resources, institutions, and a partner of comparable power.

Referendum-based legitimation and a legal right of termination are therefore not equivalent to practical reversibility. The latter requires backup providers of functions, transition mechanisms, national capabilities, and financial reserves.

Boundary Sovereignty

Malta’s strongest mechanism is its ability to define the limits of participation. The Constitution specifies who may use its territory, under what circumstances foreign forces may be present, and which forms of permanent deployment are prohibited. Neutrality functions as a legal boundary on delegation rather than as isolation.

Palau’s boundaries are also constitutionally entrenched, but they are structured differently. The transfer of major powers requires a parliamentary supermajority and a referendum, while provisions concerning nuclear and other hazardous substances impose a higher approval threshold. Once the Compact entered into force, however, a substantial share of the operational authority to determine permissible military actors shifted to the United States through the strategic-denial regime.

Thus, Malta retains direct control over the entry of external force, whereas Palau primarily retains constituent control over the regime itself, after which a long-term treaty constraint applies. This does not eliminate Palau’s sovereignty, but it shifts sovereignty from everyday operational decisions to infrequent constitutional and treaty moments.

Second-Order Sovereignty

Malta uses neutrality as a diplomatic specialization. Its foreign-policy strategy links neutral status to the role of a reliable partner in dialogue and peacebuilding. This makes it possible to convert limited military power into influence over norms of mediation, maritime security, and the European debate over the compatibility of neutrality with a common security policy.

Palau possesses a different second-order resource: international-law and climate diplomacy. In written submissions in the advisory proceedings before the International Court of Justice, Palau sought recognition that principles of transboundary harm and state responsibility apply to climate change. The small state thus seeks to influence not only the distribution of assistance but also the rules defining the obligations of major emitters.

In the defense architecture, however, Palau’s ability to change the rules is constrained by the asymmetry of the Compact. Its geostrategic value creates bargaining leverage, but the regime of exclusive U.S. access simultaneously narrows the range of permissible defense combinations.

Reproductive Sovereignty

Malta reproduces capacity through the legal continuity of neutrality, domestic institutions, education, cyber capabilities, and integration into European regulatory frameworks. The National Cybersecurity Strategy explicitly links resilience to the development of governance, capabilities, and international cooperation.

Palau reproduces the system through the Compact, a long-term trust fund, partner assistance, and constitutional procedures. The 2023 agreement expanded fiscal space and replenished the Compact Trust Fund, but budgetary dependence on grants means that resilience remains sensitive to decisions by external donors.

The key risk is a gap between receiving a function and reproducing the domestic capacity to govern it. If an external party provides defense, surveillance, and a substantial share of financing, the domestic state must retain at least the capabilities needed to define tasks, monitor implementation, negotiate agreements, and conduct scenario planning. Otherwise, delegation shifts from an instrument of sovereignty to a mechanism of institutional substitution.

Systemic Comparison

The systemic picture cannot be reduced to the 106.2-point gap. Malta generates a strong emergent effect by combining political, economic, informational, and cognitive resources: these dimensions support legal control, negotiating competence, and the ability to choose forms of cooperation. Its weak military dimension is offset not by a single patron but by a combination of domestic and external mechanisms.

Palau displays the reverse configuration. Its higher military score relative to Malta does not imply greater autonomy in defense decision-making; rather, it reflects access to a powerful external system. At the same time, political and cultural resources, constitutional referendum barriers, ocean diplomacy, and relations with multiple partners prevent Palau from being reduced to a passive protectorate.

Typology of Delegation

The comparison identifies four types of security architecture:

Modular delegation—specific functions are transferred while the state retains the governance core and can replace the provider.

Cooperative production—security is jointly produced by multiple institutions without an exclusive external center.

Compact-based delegation—a single partner assumes broad responsibility in exchange for guarantees and support.

Substitutive delegation—the external system does not supplement but displaces national capabilities, making revision practically impossible.

Malta lies between the modular and cooperative models. Palau fits the compact-based type but risks moving toward substitutive delegation if it does not reproduce its own capacity to oversee the agreement, maritime space, critical infrastructure, and external financing.

Testable Hypotheses

1. The constitutional-boundary hypothesis: delegation increases emergent sovereignty when the limits of external access are entrenched in rules that the partner cannot alter unilaterally.
2. The functional-diversification hypothesis: multiple providers of different functions increase autonomy only when dependencies do not concentrate around a single strategic center.
3. The retained-core hypothesis: a minimum domestic core of command, control, intelligence assessment, and treaty competence is a necessary condition for sovereign delegation.
4. The practical-reversibility hypothesis: the right to terminate an agreement increases sovereign agency only when a transition period, reserves, and an alternative provider of the function are available.
5. The correlated-dependence hypothesis: combining defense, budgetary, infrastructure, and diplomatic dependence on a single partner reduces emergent sovereignty more than each dependency does separately.
6. The geostrategic-rent hypothesis: strategic location can compensate for limited military resources if the state can repeatedly convert access into guarantees, financing, and institutional concessions.
7. The second-order hypothesis: a small state can partly offset the delegation of defense by influencing international rules in niches where it possesses legitimacy—neutrality, climate, ocean governance, or international law.
8. The reproduction hypothesis: delegated security remains sovereign only when the state reproduces the capacity to assess threats and revise the terms of the agreement independently of the guarantor.

Operationalization

An aggregate index alone is insufficient to test these hypotheses. Additional variables are required:

A specifically important counterfactual test asks what would happen during the first 6, 24, and 60 months after external support ended. If the state retains basic functions and can transition to another security circuit, delegation remains an instrument of autonomy. If termination produces an immediate defense, budgetary, and infrastructure collapse, the formal right of exit does not provide real sovereignty.

Conclusion

The comparison confirms the model’s central proposition: externally provided security is neither an automatic loss nor an automatic enhancement of sovereignty. Its effect is determined by the interaction of the seven mechanisms.

Malta exhibits a more autonomous architecture of delegation. Constitutional neutrality establishes boundaries, European integration expands resources, and domestic institutions support reproduction and the ability to choose among specific forms of cooperation. Its constraints remain a limited military base and structural dependence on external markets, energy, and European infrastructure.

Palau presents the sharper paradox. Delegation to the United States creates real deterrence and increases the state’s strategic value despite its minimal domestic defense base. Yet the exclusivity of the guarantor, the residual duration of U.S. defense rights, and their correlation with financial assistance reduce alternatives and reversibility. Constitutional referendum mechanisms preserve constituent sovereignty but do not eliminate the material cost of changing course.

The decisive criterion, therefore, is not who physically produces security, but who can determine its objectives, boundaries, providers, and terms of revision. Delegation becomes a source of emergent sovereignty when external protection expands the range of available choices without destroying the domestic capacity to alter the architecture.
