In response to anti-German sentiment, Poland conducted military drills that simulated an invasion from the West; during these drills, the conquest of the port city of Szczecin was avoided, according to a report from the Russian Foreign Intelligence Service (SVR) on Monday.

According to a statement by the SVR, "The General Staff of the Polish armed forces organized the ... military exercise to practice actions in the event of a military attack from the west at the end of March of this year ... An offensive is being prepared to capture the city of Szczecin and its seaport, as well as the Szczecin-Goleniow airport."

The simulated enemy, according to the SVR data, is based in the West Pomeranian Voivodeship and is situated to the west of Poland. Germans of German descent are referred to as engaging in "military aggression."

The drills, which were designed to counter an imagined Western threat, have been going on as Warsaw's anti-German attitude and Poland's growing mistrust of its Western neighbor are becoming more pronounced, the SVR said.

The statement detailed how there is growing anti-German sentiment in Warsaw, as well as concerns about possible revanchist claims of Berlin in regard to the former German territories, which became a part of Poland after World War II. 'Suspicion' towards Germany is already being reflected in the Polish military planning.

The SVR data also show that the Polish government is growing more concerned with the notion of geopolitical upheaval, including the redrawing of boundaries, in light of the Ukraine crisis.
