Migration Weaponization: How Europe Can Defuse the Threat
From weaponized borders to “return hubs,” the European Union must reclaim its sovereignty without outsourcing it
Migration was long regarded as a consequence of war, poverty, persecution, or demographic imbalance. But it can also become an instrument of power. Some states organize, facilitate, or threaten to trigger population movements in order to secure financial, diplomatic, or strategic concessions.
The border then becomes a theater of operations. Migrants are not combatants. They are the involuntary hostages of a strategy that turns human distress into political leverage.
A Weapon Without Soldiers
The weaponization of migration does not necessarily require moving hundreds of thousands of people. Sometimes, it is enough to overwhelm a border crossing, disrupt reception services, and generate images capable of dividing public opinion.
The method is now familiar: visas are issued, flights or ground transportation are organized, false information is circulated suggesting that a border has been opened, people are taken to crossing points, and the security forces that might otherwise have stopped them are deliberately withdrawn. The state behind the operation can then deny any responsibility and portray the crisis as a spontaneous movement.
This strategy belongs to the realm of hybrid warfare. It uses neither tanks nor missiles. Instead, it exploits legal obligations, political divisions, and the moral sensitivities of the targeted country. It deliberately operates in a gray zone: aggressive enough to exert pressure, but not openly military enough to justify a traditional response.
American scholar Kelly Greenhill identified 56 episodes of “coercive engineered migration” between 1951 and 2006. According to her research, the instigators achieved virtually all their objectives in 57 percent of the cases and secured at least some of what they wanted in nearly three-quarters of them. Their effectiveness stems largely from their ability to exploit political and moral divisions within the targeted country.
Europe, the Ideal Target
The European Union is especially vulnerable because it has common external borders but remains politically divided over reception policies, the distribution of asylum seekers, and the enforcement of return decisions.
The objective of migration coercion is not merely to move people across a border. It is to provoke a political crisis: confrontation among European governments, conflict between humanitarian obligations and national sovereignty, the rise of protest parties, and the radicalization of public debate.
Turkey demonstrated the method in February 2020 when it announced that it would no longer prevent migrants from attempting to reach Europe. The Council of the European Union explicitly rejected Turkey’s “use of migratory pressure for political purposes,” while acknowledging the considerable burden Ankara had assumed by hosting approximately 3.7 million refugees and migrants.
In Ceuta in May 2021, more than 8,000 people, including roughly 2,000 children and unaccompanied minors, crossed the border after Moroccan controls were relaxed amid a diplomatic dispute between Rabat and Madrid.
Belarus took the process a step further by organizing flights and domestic transportation for foreign nationals and directing them toward the Lithuanian, Latvian, and Polish borders. The European Union responded by extending its sanctions to individuals and entities involved in the operation.
Finland has also accused Russia of facilitating the arrival of third-country nationals at its eastern border. Weaponized migration is therefore by no means limited to poor countries or states in the Global South.
Calling it a “weapon of the Third World” would consequently be inaccurate. It would be more appropriate to describe it as a weapon of asymmetric powers: states that use their geographical position and control over migration routes to compensate for economic, diplomatic, or military disadvantages.
Selective Immigration as Collateral Damage
When migration becomes a weapon, the destination country loses control over the number, pace, and profile of arrivals. An emergency imposed at the border takes precedence over a planned policy based on economic needs, professional qualifications, and integration capacity.
Selective immigration depends on anticipation. Its purpose is to attract physicians, engineers, researchers, entrepreneurs, or workers needed in sectors facing labor shortages. A weaponized migration wave pursues the opposite objective: unpredictability, saturation, and the perception that the state has lost control.
It also creates confusion among legal immigration, asylum applications, illegal entry, and operations deliberately organized by foreign governments. Public distrust eventually spreads to every form of immigration. Legal pathways become more restrictive, administrative delays increase, and the skilled people a country wants to attract may choose other destinations.
Europe could therefore find itself in a paradoxical position. It may need immigration to compensate for its aging population and labor shortages while becoming politically incapable of organizing it.
Migration sovereignty means neither opening every border nor closing them all. It means retaining the power to choose.
Offshore Centers: A Solution or a New Dependency?
To regain control, several European governments are considering “return hubs” in third countries. These centers would accommodate people whose asylum applications have been definitively rejected while arrangements are made for their return to their countries of origin.
The new European return framework negotiated in June 2026 allows such facilities to be established. This policy responds to a genuine weakness: Europe’s return systems remain fragmented, and removal orders are still too rarely enforced. In 2025, the European Commission estimated the effective return rate at approximately 20 percent. More recent figures nevertheless indicate some improvement, with 135,460 people returned to third countries out of 491,950 ordered to leave in 2025.
Return hubs could centralize consular procedures, prevent some rejected applicants from disappearing into the underground economy, and facilitate repatriation. But they contain a fundamental contradiction: to regain control over its borders, Europe would entrust a sovereign function to governments paid to perform it.
A host country could demand more financial assistance, additional visas, trade benefits, investments, or diplomatic support. Once it became indispensable, it could threaten to suspend the agreement, refuse further transfers, or release the people accommodated in the centers. The service provider hired to solve the problem would then acquire a new means of coercion.
Externalization may therefore relocate Europe’s vulnerability without eliminating it. Having already paid certain countries to prevent migrants from leaving, Europe would now pay them to hold those it cannot return.
The legal obstacles are equally serious. In considering the agreement between Italy and Albania, the advocates general of the European Court of Justice acknowledged that a member state may operate detention and return centers outside the European Union, but only if all protections required under European law continue to apply. Moving the center does not move the law.
The Office of the United Nations High Commissioner for Refugees likewise considers return hubs to be, at most, a complementary measure. They should be used only for people whose asylum applications have been rejected following a full and fair procedure, when direct return is temporarily impossible. Any stay must remain temporary and genuinely oriented toward departure.
Without that prospect, offshore facilities would become human parking lots: no return, no admission to Europe, and no meaningful integration into the host country.
How Can the European Union Defuse This Strategy?
The first response must be early detection. The European Union should create a permanent monitoring mechanism bringing together Frontex, Europol, diplomatic services, intelligence-sharing structures, and transportation companies. Its task would be to identify anomalies such as sudden increases in visa issuance, new airline routes, online campaigns promising easy passage, or organized transportation toward a border.
The second response should target the logistical chain. Sanctions must not be limited to the government behind the operation. They should also apply to airlines, travel agencies, hotels, transportation companies, banks, and intermediaries knowingly involved in it. The European response to Belarus showed that disrupting the supporting network can rapidly undermine such an operation.
The third response must be financial. European aid granted to transit countries should include precise conditionality: automatic suspension of certain payments when state-directed instrumentalization is demonstrated, independent oversight of the use of funds, and safeguards preventing every new crisis from triggering a general renegotiation. Foreign aid must not become tribute paid under threat.
The fourth response concerns internal European solidarity. When a member state faces an organized operation, Frontex personnel, registration capacity, judges, interpreters, and emergency reception facilities should be deployed automatically. The instigating government must understand that it is not negotiating separately with Greece, Poland, Finland, or Spain, but confronting the European Union as a whole.
The fifth priority is to accelerate asylum procedures without abandoning individual review. A decision delivered within weeks protects the right of asylum more effectively than a process lasting several years. It allows authorities to distinguish more quickly between people entitled to protection and those required to leave, while reducing the strategic value of administrative saturation.
The sixth response is a genuine European readmission policy. Visa access, development assistance, trade preferences, and consular cooperation should be coordinated at the European level. A country that systematically refuses to readmit its own nationals should not continue to receive the same benefits without conditions.
Finally, offshore return hubs should be authorized only as temporary instruments, for limited numbers of people, under clearly defined jurisdiction, permanent European monitoring, and immediate suspension in the event of violations. Agreements with several host countries might reduce dependence on a single partner.
But diversified dependence remains dependence. The ultimate objective must still be effective return to the country of origin.
Sovereignty Without Inhumanity
Europe must avoid two opposite mistakes. The first would be to deny the reality of weaponized migration for fear of undermining the right of asylum. The second would be to treat every migration movement as an attack and every migrant as an enemy.
The people transported to a border remain the first victims of these operations. Protecting the border and protecting those individuals are therefore not incompatible goals. A firm policy can remain consistent with the rule of law if it examines claims individually, rescues people in danger, and punishes the organizers rather than those they manipulate.
The migration weapon fires no projectile. It targets the political system of the adversary. Its principal objective is not always to make migrants enter, but to inject fear, division, and doubt into the heart of democratic societies.
Europe will not neutralize this strategy through uncontrolled openness or indiscriminate closure. It will do so when it becomes capable of protecting those entitled to protection, returning those who have no legal right to remain, and refusing to let foreign governments determine—on Europe’s behalf and for a price—the conditions under which its sovereignty is exercised.
