OPINION: Poland sounds the alarm — prepare for escalation

OPINION: Poland sounds the alarm — prepare for escalation

Introduction: Gdansk, eyes wide open

A summit that is anything but routine

On June 26, 2026, at the conclusion of the Eastern Flank Summit in Gdansk, Polish Prime Minister Donald Tusk delivered words that should have sent tremors through Europe's foreign ministries: "We unanimously share the conviction that the situation is highly unstable, and that various forms of escalation can be anticipated in the coming weeks and months." This was not hollow rhetoric. It was a sharp warning grounded in concrete intelligence.

Two NATO member states on the eastern flank — Poland and Latvia — jointly signaled that Moscow may be preparing a military provocation against the Baltic states or Poland. Latvia's intelligence agency was unequivocal: "We are observing signs that Russia is preparing military provocations targeting the Baltic nations or Poland."

A documented hybrid threat

Latvian intelligence specified the nature of this threat: it is not a conventional frontal invasion, but a hybrid campaign combining missiles, drones, and political messaging. The objective would be to send a brutal signal to European capitals: stop your support for Ukraine, or face your own security crises. Moscow would thus be testing the solidity of the Atlantic alliance, probing for the crack where resolve is wavering.

A senior political official from a NATO country, quoted by The Guardian on June 26, 2026, confirmed receiving intelligence that Vladimir Putin "is planning something against the Baltic states," in a desperate gamble to "go all-in" as Russia struggles on the Ukrainian front.

Pressure mounts: Moscow with its back to the wall

Ukraine strikes deep, Putin panics

The immediate geopolitical context is decisive. Ukraine has been conducting a deep-strike campaign on Russian territory for several weeks, targeting military and industrial infrastructure hundreds of kilometers from the front lines. Arms factories, fuel depots, oil installations — the pressure on Moscow is real and documented. According to the ISW (Institute for the Study of War), 28 strikes on oil infrastructure were recorded in June 2026 alone.

Facing this mounting pressure, Western military sources are expressing a specific fear: Putin may perceive this escalation on his own soil as an unbearable humiliation. The temptation to strike back at the most vulnerable flank — the Baltic states and Poland — is becoming an option that Moscow is seriously considering, according to Alliance intelligence services.

The Suwalki Corridor: maximum friction point

The Suwalki Corridor — that narrow strip of land connecting Poland to Lithuania, separating the Russian exclave of Kaliningrad from Belarus — remains NATO's geographic Achilles heel. Security experts such as Taras Zhovtenko, cited by Euromaidan Press in late 2025, had warned that Russia might seek to establish a temporary foothold over this corridor — not to occupy it permanently, but to demonstrate strength and paralyze the Alliance. That scenario is no longer theoretical.

Russian propaganda has for months been feeding the narrative of a supposed NATO blockade of Kaliningrad — a fabricated justification, designed to legitimize military action in the eyes of the Russian public and certain international partners.

NATO confronting its own fractures

Washington plays with its allies' nerves

Alongside Russian provocations, the eastern flank must contend with a fundamental uncertainty: the reliability of the United States under the Trump administration. In May 2026, the deployment of 4,000 American soldiers to Poland was cancelled at the last minute — some were already en route. Defense Secretary Pete Hegseth announced a six-month review of America's military presence in Europe, conditioning Washington's commitment on allies paying their "dues." This transactional rhetoric undermines the very foundations of collective deterrence.

According to The Guardian's in-depth investigation published on June 27, 2026, one precise scenario is now haunting Eastern European officials: what if Russia attacked, and the United States did not intervene? This question — once unthinkable in Alliance corridors — is now being voiced openly in the region's capitals.

Germany compensates, Europe adapts

In the face of partial American withdrawal, several European nations have intensified their commitments. Germany is deploying a permanent brigade to Lithuania — its first permanent overseas military base since World War II. France, the United Kingdom, and Denmark have dispatched additional fighter jets under Operation Eastern Sentry, launched after Russian drone incursions into Polish airspace in September 2025. These efforts are real, but they do not replace the sheer weight of American force.

NATO members committed at the 2025 The Hague summit to raising defense spending to 5% of GDP by 2035, with 3.5% for baseline capabilities. Poland and the Baltic states, already close to that target, are showing the way — but many Western European states remain well short of the mark.

Donald Tusk: Europe's clearest voice

A prime minister who pulls no punches

Donald Tusk has consolidated his role as Europe's most direct spokesperson on security matters. At the Gdansk summit, he declared: "Let this be a warning to all those who are planning something harmful against one of us or our countries." This blunt formulation, unmistakably addressed to Moscow, stands in sharp contrast to the usual diplomatic language. Tusk knows that clarity is itself a tool of deterrence.

Tusk had already noted in February 2026 that defending NATO's eastern flank against a potential Russian attack would cost at least 1.2 trillion euros — 24 times Poland's defense budget — according to Foreign Minister Radosław Sikorski. This colossal figure is not meant to discourage, but to dramatize the urgency of a serious collective commitment.

Poland on the front line — by choice

Poland has become, de facto, the military pivot of Eastern Europe. It hosts NATO bases, invests massively in its own defense — notably refusing to send its Patriot batteries to the Middle East despite an American request, according to AA in March 2026 — and seeks to attract more Allied troops to its soil. Tusk's government has adopted a simple doctrine: the security of Ukraine is the security of Poland, and the security of Poland is the security of all of Europe.

Defense Minister Władysław Kosiniak-Kamysz had described Operation Eastern Sentry as "one of the greatest operations in NATO's history," underscoring the breadth of the collective response to the violation of Polish airspace in September 2025. That precedent accelerated defensive coordination across the entire eastern flank.

Latvian intelligence: the alarm coming from within

Riga steps out of diplomatic restraint

Latvia's intelligence agency took an unusual step by making public, on Monday, June 22, 2026, its assessment of Russia's preparations for military provocations against the Baltic states or Poland. This transparency is not naïve — it is itself an act of deterrence. By exposing Moscow's presumed intentions, Riga forces the Alliance to respond, prevents a surprise operation, and engages allies' accountability.

The agency was precise about its limits, however: Russia does not have the capacity to open a second large-scale front. It is deeply committed in Ukraine. But a targeted hybrid operation — a few missile strikes on civilian infrastructure, a few drones penetrating an allied airspace, a few sabotage operations — could be enough to trigger political panic without setting off open war.

Sabotage: Moscow's weapon of choice

Russia has already used this arsenal in the past. DHL incendiary packages exploding in Poland, Germany, and the United Kingdom in the summer of 2024. Drones crossing the Polish border in September 2025 — 19 Russian drones penetrating the airspace of a NATO member state, forcing the evacuation of three provinces. These acts were deliberately calibrated to remain below the threshold triggering Article 5 of the North Atlantic Treaty. It is the Russian doctrine of controlled escalation, and it works.

Western military sources quoted by The Guardian have expressed concern that Moscow may respond to mounting pressure in Ukraine with reprisals against states perceived as facilitating Ukrainian strikes — particularly if long-range Ukrainian drones were to be launched from NATO countries, a scenario that Putin explicitly threatened to target on June 23, 2026.

The Ankara summit in the crosshairs

Tens of billions for collective defense

The NATO summit scheduled for July 7 and 8, 2026 in Ankara promises to be crucial. Secretary General Mark Rutte announced defense contracts worth tens of billions of dollars to be concluded at the event. It is the Alliance's opportunity to translate rhetorical commitments into concrete capabilities: ammunition, air defense systems, command and communication assets.

Some analysts, such as Simon Gros, are speaking of a "NATO 3.0" — a transatlantic rebalancing in which Europe would assume a growing share of its own security burden, with the United States in a support role rather than on the front line. This model is more robust over the long term, but its implementation in a context of strategic urgency is treacherous.

BALTOPS and the naval show of force

In parallel, the BALTOPS exercise is underway in the Baltic Sea with 20 vessels, 6,000 personnel from 15 nations. This demonstration of maritime cohesion sends a signal to Moscow: NATO's maritime flank is monitored, coordinated, and ready. Naval exercises in the Baltic have become political statements as much as military operations.

The Finnish Forward Land Forces, with the deployment of a Swedish battlegroup to Boden in June 2026, complete the picture of an Alliance extending its presence toward the northeast. The integration of Finland and Sweden into NATO has fundamentally changed the geography of deterrence in Northern Europe.

What Poland demands of Europe

Solidarity is not optional

Warsaw's message to its European partners is clear and repeated: the security of the eastern flank is not a regional matter, it is an existential question for all of Europe. Polish Foreign Minister Sikorski warned that Putin's rhetoric amounted to "an announcement of provocation," according to Euromaidan Press on June 24, 2026. There is no longer any margin for ambiguity or complacency.

Polish FM Sikorski also warned against any hostility within the EU toward Germany or Ukraine, recalling that such divisions serve only one power: Russia. European unity is the sine qua non of credible deterrence.

Preparing populations, not just armies

Beyond military mobilization, Poland advocates for increased civil preparedness. The three border provinces that suffered Russian drone incursions in September 2025 demonstrated the vulnerability of civilian populations to hybrid warfare. Alert systems, shelters, evacuation plans — these too-often-neglected dimensions of national defense are now at the heart of Polish concerns.

Warsaw made clear that it intends to "prepare in a coalition of nations directly exposed to this risk," in Tusk's words following the Gdansk summit. This is not passive defensive posturing — it is an active mobilization of national and regional resilience.

Forward military bases: a real but insufficient presence

Forces deployed on the eastern flank

NATO currently has four multinational battlegroups deployed in Estonia, Latvia, Lithuania, and Poland — the Enhanced Forward Presence (eFP), created after Russia's annexation of Crimea in 2014. These forces each number roughly 1,000 to 1,500 soldiers. In response to the events of 2022, the Alliance reinforced these battlegroups and added others in southeastern flank countries. But these numbers remain symbolic compared to the 300,000 soldiers Russia could theoretically mobilize on this flank.

The reality of forward deterrence is this: the deployed forces are not there to stop an invasion — they are there to witness it. Their presence guarantees that any Russian aggression would automatically be an aggression against multiple NATO nations, triggering the Article 5 mechanism. It is deterrence by engagement, not by firepower. It works — as long as the credibility of Article 5 is maintained.

The urgency of scaling up

US General Christopher Cavoli, Supreme Allied Commander Europe (SACEUR), warned in early 2026 that NATO forces in Europe needed to transition from "deterrence presence" to "territorial defense" — a major qualitative shift that implies larger troop numbers, pre-positioned ammunition stockpiles, and proven rapid reinforcement plans. The process is underway, but it is far from complete given the threat documented by Latvian intelligence.

Poland in particular is pushing for these battalions to be reinforced to brigade level — meaning 3,000 to 5,000 soldiers per grouping — with pre-positioned heavy armored capabilities. If this transformation materializes at the Ankara summit in July 2026, it would significantly alter Moscow's strategic calculus before any attempt at provocation on the eastern flank.

Conclusion: The alarm has sounded — who is listening?

Tusk is right, the danger is real

Poland is not inventing a peril to justify its military spending or to secure more allied support. It analyzes, documents, and warns with remarkable consistency — and the facts have systematically proven it right. The Russian aggression against Ukraine in 2022 was foreseeable to anyone who listened to Warsaw. The hybrid provocations of 2025 had been anticipated. The June 26, 2026 alert deserves the same level of seriousness.

NATO put to the test of its credibility

The Ankara summit in July 2026 will be a moment of truth. NATO allies must demonstrate through concrete actions — deployments, contracts, firm commitments — that the Alliance is prepared to defend every inch of its territory. A tepid response would be precisely the signal that Moscow is waiting for before acting. Deterrence is not a permanent state — it is a continuous performance that erodes if not maintained. Poland has sounded the alarm. It is for Europe to decide whether it hears it.

Columnist's transparency note

Who I am and where I stand

I am a columnist and analyst specializing in European defense and geopolitical affairs. I am not military personnel, I have no access to intelligence services, and I have never claimed to have direct government sources. My analysis rests on open sources — international press, research institute reports, official statements — which I strive to cross-reference and verify.

My biases and my limits

I am pro-Ukrainian and deeply convinced that defending NATO's eastern flank is a just and urgent cause. This bias colors my perspective — I do not hide it. On the precise imminence of a Russian provocation, I depend on intelligence assessments made public — and those assessments carry their own margins of error. I do not know with certainty whether a provocation will occur, when, or in exactly what form. What I do know is that the warning signals are real and documented.
