Polish Foreign Minister Radoslaw Sikorski said this in an interview with Kathimerini, according to Ukrinform.

"Make no mistake, Russia has already declared war on us, it just doesn't involve tanks. The Kremlin is waging a frantic campaign to fracture our societies. They use disinformation to pit Poles against Ukrainians, and they orchestrate crude provocations like throwing pig heads at mosques," he said.

According to the minister, Europe is dealing with state-sponsored sabotage, including assassination plots, attempts to derail trains, commercial arsons across Europe, and incursions by hostile drones into the airspace of EU countries.

"Just a few days ago, another Russian cruise missile violated Polish airspace," Sikorski added.

The foreign minister noted that Poland has more than five centuries of experience resisting Russian imperialism and therefore knows all of its tricks.

"What has changed is the scale and desperation. There is a clear correlation here, the worse Russia performs on the battlefields of Ukraine, the more aggressively the Kremlin tries to destabilize the West to break our solidarity with the victim of their aggression," he said.
