Poland Warns NATO That Russia and Belarus Are Weaponizing Illegal Migration Against the Alliance

In August 2021, something unprecedented began happening on Poland's 418-kilometer border with Belarus. Thousands of people — Iraqis, Syrians, Afghans, Yemenis, and nationals of several African countries — started appearing at the frontier, guided through Belarusian forests by border guards working not to stop them but to push them forward [1]. The numbers were staggering: from roughly 120 attempted crossings in all of 2020, the figure surged to 35,000 in 2021 [2]. By early 2026, the cumulative total of attempted illegal crossings at the borders of Poland, Lithuania, and Latvia had exceeded 200,000 [3].

Polish officials and NATO allies call it weaponized migration — the deliberate use of human beings as instruments of geopolitical pressure. Critics counter that the "weapon" framing obscures Poland's own legal obligations to asylum seekers and the genuine humanitarian crises driving people from their home countries. Both sides cite evidence. Neither is entirely wrong.

The Numbers: A Border Crisis in Scale

The scale of attempted crossings at the Poland-Belarus border has remained elevated since the initial surge, though the year-to-year trajectory tells a more complex story than a simple escalation.

After the 2021 peak of 35,000 attempts, crossings dropped to 15,700 in 2022 following Poland's initial barrier construction [2]. But the numbers climbed again — to 26,000 in 2023 and 30,090 in 2024, a 16% year-over-year increase [4]. In 2025, roughly 29,900 attempts were recorded [5]. Then came a dramatic collapse: in the first quarter of 2026, only 158 attempts were logged, compared to 3,306 in the same period of 2022 — a 96% decline that Polish authorities attribute to new legal measures and hardened infrastructure [6].

Pre-crisis, these numbers were negligible. The Polish Border Guard's annual reports for 2018 and 2019 recorded only a few hundred irregular crossing attempts along the Belarus frontier. The current figures represent an increase of several orders of magnitude.

Poland bears the heaviest burden among NATO's eastern flank states, but it is not alone. Lithuania recorded 4,100 irregular crossings in 2021 — a twelvefold increase from the prior year [7]. Latvia saw applications for international protection more than triple [7]. Finland faced a separate but related campaign beginning in late 2023, when nearly 1,000 third-country nationals crossed from Russia, many arriving on bicycles in Arctic temperatures of minus 20 degrees Celsius [8]. Helsinki closed its entire 1,340-kilometer border with Russia in December 2023, calling the arrivals an act of hybrid warfare [9].

The Evidence for State Direction

The case that Belarus is orchestrating — rather than merely tolerating — irregular migration rests on several categories of evidence.

First, Belarusian President Alexander Lukashenko has been remarkably candid. After videos surfaced in 2021 showing Belarusian border guards assisting migrants in crossing into EU territory, Lukashenko acknowledged it was "absolutely possible" that his forces were involved [1]. His government had, in May 2021, begun issuing automatic entry visas to Iraqi and Syrian nationals, creating what investigators have called "asylum tourism" [10].

Second, operational evidence has accumulated. Frontex helicopter footage captured a group of migrants accompanied by a Belarusian border guard vehicle near the Polish border [7]. Lithuanian officials and migrants themselves have reported that some smugglers transporting people to the border were being paid by the Belarusian state, and that soldiers were "directly involved" in the logistics [1]. In December 2025, Polish authorities discovered a hidden tunnel through which over 180 migrants had crossed — the fourth such tunnel found that year, with construction attributed to Belarusian hybrid warfare tactics [11].

Third, the logistical infrastructure has a clear state footprint. Belarusian state tourism agencies were implicated in issuing flight tickets and entry guarantees. The route was industrialized: migrants flew to Minsk from Iraq's Kurdish region — primarily from Erbil, Shiladze, and Sulaymaniyah — via Dubai, Turkey, Lebanon, or Ukraine after Iraq suspended direct flights under EU pressure [10]. Once in Belarus, they were bused to the border.

Russia's role is less operationally visible but strategically central. The Foundation for Defense of Democracies, in testimony before the U.S. House Foreign Affairs Committee in February 2026, described the campaign as coordinated between Moscow and Minsk, with migration surges correlating to Russian battlefield setbacks in Ukraine and periods of intensified Western sanctions [12]. The Henry Jackson Society's November 2025 analysis concluded that Russia "deliberately engineers migration surges to pressure NATO states and compensate for its battlefield reversals" [13].

Who Comes, and What Happens to Them

The migrants channeled through Belarus are predominantly from countries experiencing armed conflict or severe instability. Iraqi Kurds have constituted the largest single group, followed by Syrians, Afghans, Yemenis, and nationals of several African countries including Cameroon and the Democratic Republic of Congo [10] [1].

Many of these individuals would have had legitimate grounds to claim asylum under the 1951 Refugee Convention — particularly Syrians, Afghans, and Iraqis from conflict-affected regions. Before the Belarus route emerged, the primary pathways for these populations into the EU ran through Turkey and the Mediterranean, or through the Balkans. The Belarus route offered something faster and, initially, cheaper: a complete package including visa, flight, and guided border crossing costing between €12,000 and €15,000 [10].

Individual smugglers have profited substantially. A Belarusian smuggler who confessed to Polish prosecutors reported earning €5,000 to €6,000 per migrant [14]. Europol operations have dismantled multiple networks: in one case, 61 people were arrested across the EU for running a criminal network worth an estimated €16 million in money flows, focused on smuggling along the EU-Belarus border [15]. Another operation netted 11 suspects — Polish, Russian, Ukrainian, and Georgian nationals — who were organizing crossings and laundering proceeds through property investments and cryptocurrencies [16].

The extent to which money flows trace back to the Belarusian or Russian state, versus independent criminal enterprises, remains partially unresolved. Europol investigations have established that the networks rely on both state-facilitated infrastructure (visas, flights, border access) and private criminal logistics (transport within the EU, document fraud, laundering). The state provides the permissive environment; organized crime fills in the operational details.

The Human Cost

The toll on migrants themselves has been severe, and is documented by multiple human rights organizations.

At least 87 deaths have been recorded in the border zone since 2021, though the true figure is likely higher because independent observers, journalists, and aid organizations have had limited access to the Belarusian side [17]. Causes of death include hypothermia, drowning in border marshlands, and injuries sustained during crossing attempts or encounters with security forces.

Human Rights Watch, in a December 2024 report, documented what it called "brutal pushbacks" — Polish border and law enforcement officials unlawfully forcing people back into Belarus without considering their protection needs [17]. Asylum seekers described a pattern of abuse including beatings with batons, pepper spray, rubber bullets, dogs set on them, and confiscation or destruction of mobile phones [17]. Oxfam's reporting corroborated these accounts, describing people "trapped, pushed back and tortured" [18].

In 2024 alone, NGOs recorded 13,600 pushbacks by Poland, 5,388 by Latvia, and 1,002 by Lithuania [19]. These summary collective expulsions violate the EU Charter of Fundamental Rights, Article 3 of the European Convention on Human Rights, and the prohibition on refoulement under international refugee law, according to the European Council on Refugees and Exiles [20].

Poland's position is that the border constitutes an active security threat. In May 2024, a Polish soldier was fatally stabbed by an individual attempting to cross the border — an event that prompted the reinstatement of a buffer zone and intensified enforcement [21]. Polish authorities have reported multiple incidents of migrants armed with improvised weapons, including Molotov cocktails [5].

Poland's Response: Walls, Shields, and Asylum Suspension

Poland has responded with the most extensive border fortification program in the EU's history, spanning three phases of escalating investment.

The first phase, completed in 2022, was a 180-kilometer steel barrier costing approximately €370 million [22]. The second phase added a 206-kilometer electronic surveillance system — 3,000 cameras with night vision and motion sensors — at a cost of €71.8 million, completed in early 2023 [22]. The third and most ambitious phase is East Shield, a €2.3 billion defensive network launched in November 2024 spanning 700 kilometers along borders with both Belarus and Russia's Kaliningrad exclave. East Shield includes intelligence, surveillance, and reconnaissance systems, forward operating bases, logistics nodes, and anti-drone systems with radar-controlled guns and missiles [23] [24].

The physical infrastructure has been effective at reducing successful crossings. Despite nearly 30,000 attempted breaches in 2025, the actual number of successful illegal entries dropped to negligible levels [5]. But the most dramatic reduction — the 96% drop recorded in early 2026 — followed a legal rather than physical measure.

In March 2025, Poland's government implemented a regulation suspending the right to seek asylum along the entire Belarus border for 60 days, with provisions for indefinite parliamentary renewal [25]. The law allows border guards to reject asylum claims outright in the border zone. In its first week, 12 asylum claims were rejected under the new framework [26].

This measure drew sharp condemnation. Amnesty International called the suspension "flagrantly unlawful," arguing that "EU member states like Poland are playing politics with the rights of refugees and migrants" [27]. Human Rights Watch urged Poland to scrap the bill entirely [28]. The European Council on Refugees and Exiles warned it created a risk of "chain refoulement" — return to possible abuse in countries of origin [20].

Poland's government, now led by Prime Minister Donald Tusk's centrist Civic Coalition, has maintained the policy. The EU's commissioner for internal affairs and migration praised Poland for protecting the EU's eastern frontier from "weaponised" migration, calling it "Europe's first line of defence" [21] — a framing that illustrates how the security narrative has gained acceptance even among EU institutions traditionally committed to asylum rights.

The Strategic Calculus: What Moscow Wants

Analysts identify several overlapping Russian objectives behind the weaponized migration campaign.

The most immediate goal is to strain NATO cohesion by exploiting the alliance's internal fault lines on refugee policy. Migration has been among the most divisive issues in European politics since 2015, and Russia's campaign deliberately reactivates those divisions [12]. When Poland or Finland closes borders and suspends asylum rights, it creates friction with Western European allies and human rights institutions — friction that costs diplomatic capital regardless of which side prevails.

A second objective is resource diversion. Poland now deploys thousands of soldiers and border guards along the Belarus frontier. The East Shield program alone will absorb €2.3 billion in defense spending that might otherwise go toward conventional military capabilities or NATO force contributions [23]. For Russia, the cost of facilitating a few thousand migrants is trivial compared to the security expenditure it forces on Poland.

Third, the campaign serves as a testing ground for hybrid warfare techniques. The Global Initiative Against Transnational Organized Crime has documented how weaponized migration is paired with other tools — cyberattacks, drone incursions, sabotage of undersea cables and transport infrastructure, and information operations [29]. Poland's 2025 presidential election coincided with a surge in both border crossing attempts and Russian-origin disinformation on Polish social media [5].

The timing of migration surges supports the strategic interpretation. Spikes have correlated with EU sanctions decisions, NATO expansion milestones (particularly Finland's 2023 accession), and periods of intensified fighting in Ukraine [13] [12].

The Counterargument: Overstating Russian Agency

The strongest case against the "weaponization" framing does not deny Belarusian state involvement — the evidence for that is substantial — but questions whether the security narrative overstates Russian strategic control and understates other factors.

First, the source countries — Syria, Iraq, Afghanistan, Yemen, the DRC — are experiencing genuine humanitarian crises that generate migration pressure independent of any state orchestration. The people arriving at the Polish border are not manufactured; their desperation is real. The UNHCR's 2025 data shows global refugee populations continuing to grow, with Germany hosting 2.7 million and even Poland itself hosting over 1 million — predominantly Ukrainians [30].

Second, Poland's domestic political incentives to frame border policy as a national security matter are considerable. The migration crisis has been electorally potent for both the previous Law and Justice (PiS) government and the current Civic Coalition administration. Tusk's decision to suspend asylum rights — after campaigning partly on restoring rule-of-law norms — suggests that the political rewards of a hardline border stance transcend party lines [21] [27].

Third, the EU's own visa and asylum architecture contains gaps that migration networks exploit regardless of state sponsorship. Before the Belarus route, many of the same nationalities used the Balkans or Mediterranean routes. The Belarus pathway was more efficient and briefly cheaper, but the underlying demand for passage into the EU existed — and will continue to exist — independently of Lukashenko or Putin.

Oxfam's assessment captures this critique directly: Poland is viewing the border "from a national security perspective" rather than as a humanitarian and asylum issue, and "people should be able to apply for asylum, irrespective of the political game at hand" [18].

What Remains Unresolved

Several critical questions lack definitive answers.

The precise chain of command between Moscow and Minsk on migration operations remains partly opaque. While the strategic alignment is clear, whether specific surges are directed by the Kremlin or initiated independently by Belarusian authorities is difficult to establish from open-source evidence alone.

The true death toll at the border is unknown. The 87 documented deaths almost certainly undercount the actual figure, given restricted access to the Belarusian side and the dense, marshy terrain of the Białowieża Forest region where many crossings occur [17].

Lithuania's referral of the matter to the International Court of Justice — seeking to establish state accountability for Belarus's role in human smuggling — could set a legal precedent, but the case remains in early stages [31].

And the fundamental tension at the center of this story — between sovereign border security and international obligations to refugees — remains unresolved. Poland has built one of the most formidable border defense systems in Europe. It has also, according to multiple international human rights bodies, violated the rights of thousands of people in the process. Both statements are supported by evidence. The question of which takes precedence has no easy answer, and the people caught between the two imperatives continue to pay the highest price.
