Washington has alerted Warsaw that Russia is allegedly planning an armed incursion into Polish territory as a test of NATO's response, according to reports.

Sources close to Polish President Karol Nawrocki indicated that the United States has been providing ongoing warnings to Poland about this potential provocation. The alleged Russian plan involves crossing into Polish territory, with vital infrastructure possibly targeted by missiles and drones. The goal of this maneuver would be to create a crisis that could pressure Western nations into halting their support for Ukraine.

Polish security experts have also raised concerns, suggesting that Russia and Belarus might orchestrate a limited incursion involving a small number of troops across the NATO border. Such an incursion could involve air strikes on critical infrastructure like power stations, forcing Poland to activate its air defense systems.

According to Polish sources cited by Onet, Russia might attempt to frame a territorial incursion as an accidental GPS navigation error or an emergency helicopter recovery. The underlying strategy reportedly assumes that the U.S. would compel Poland to negotiate rather than engage militarily, which the Kremlin could then present as a strategic victory to demand an end to Western military assistance for Ukraine.

A worst-case scenario for NATO, as described by sources, would involve Russia undermining Polish sovereignty, forcing the withdrawal of Western support for Ukraine, and exposing NATO as ineffective.

Such ground-based attacks could originate from Kaliningrad, which borders northern Poland, or from Belarus to the east. Russia's approach relies on targeted, limited provocations to probe NATO's defenses, given its substantial military commitments in Ukraine, which preclude a large-scale war.

While Poland is a critical security partner for Ukraine, recent strains have emerged over agricultural trade and historical grievances. Moscow is reportedly expected to attempt to exacerbate these divisions.

A source close to the Polish president stated that the U.S. is "systematically informing Poland about ever-new Russian plans for a conventional attack on Nato's eastern flank, from which Poland is by no means excluded." Two other sources, an ambassador to a NATO ally and a source within the Polish defense ministry, confirmed a significant risk of incursions into Poland and the Baltic states. However, European security sources suggest that a provocation targeting Poland would be more strategically advantageous for Russia than targeting the Baltics.

A Baltic security source indicated that these plans are currently under discussion in Moscow. Russia may also attempt to attribute the provocation to Ukraine after it occurs.

Recent naval exercises in Latvia, involving the U.S. Navy and Marines, were reportedly intended to signal to Russia that an attack on NATO's eastern flank would be considered an attack on U.S. troops. Poland has conducted similar exercises, according to a member of the Polish Ministry of Defense leadership.

NATO could potentially respond to attacks by targeting locations such as Kaliningrad, as suggested by German air force chief Holger Neumann. He also identified the Kola Peninsula and the Black Sea as potential targets. Neumann affirmed that Germany would defend "every inch" of NATO territory, including Poland if necessary.

In a separate development, Ukraine's top military commander, Oleksandr Syrskyi, stated in a recent interview that Ukrainian forces are preparing for a potential new Russian attack from the north, originating from Russia's Bryansk region. He indicated that an advance on Kyiv was unlikely, as was an attack from neighboring Belarus.

Syrskyi suggested that the objective of such an operation would not be to capture Kyiv, but rather to seize territory in Ukraine's Chernihiv region. This strategy would aim to stretch the Ukrainian front line and deplete its reserves. He also noted indications of Russian troop exhaustion and a decline in the intensity of frontline battles, with Russian frontline activity decreasing by 30 percent.
