Russia on Wednesday expressed anger that President Vladimir Putin has not been invited to ceremonies marking the 80th anniversary of the outbreak of World War II in Poland later this year.

The foreign ministry voiced its “bewilderment” upon learning of Warsaw’s plan to mark the anniversary of the start of WWII only with Poland’s close allies — members of the European Union and NATO and several ex-Soviet nations.

Russia accused the Polish authorities of ignoring “historic logic” and seeking to turn the September commemorations into a “secret” meeting.

“Despite our Homeland’s unquestionably decisive contribution to the defeat of Hitler’s Reich and the liberation of Poland from the Nazi aggressors there is no place for Russia in this plan,” the foreign ministry said in a statement.

“Let it be on the current Polish authorities’ conscience.”

Polish President Andrzej Duda’s press office said “the key to the invitations isn’t historical but rather, contemporary.”

“These dramatic events will be commemorated by Poland and the countries we work closely with today for peace in a world based on the principles of observing international law,” the press office told AFP.

Ahead of the German invasion of Poland on 1 September, 1939 Germany and the Soviet Union agreed to carve up eastern Europe between them in a secret clause of the infamous Molotov-Ribbentrop Pact.

The USSR, allied with Nazi Germany, attacked Poland on September 17, 1939, and occupied part of its territory before Hitler launched a surprise attack against the Soviet Union on June 22, 1941.

Duda’s aide Krzysztof Szczerski suggested that invoking historical logic “in the context of September, 1939 is problematic,” adding Poland and its allies respected international law.

“Breaking these rules was the mark of the aggressors in 1939 and remains the biggest threat to peace today,” he was quoted as saying.

Moscow has faced Western condemnation for its 2014 annexation of Crimea and support for separatists in eastern Ukraine as well as military support for President Bashar Assad in Syria, among other crises.

Moscow insists the West often forgets that the Soviet Union saved the world from Hitler.

An estimated 27 million of the former Soviet Union’s soldiers and civilians were killed in WWII and the Red Army’s triumph in the deadliest war in history is seen as a huge point of pride in Russia.
