Russia has become locked in a dispute with Poland and the Baltic States over the origins of WWII after the European Parliament passed a resolution in September on the history of the conflict. The resolution claimed that the 1939 non-aggression treaty between the Soviet Union and Nazi Germany led to the start of the war. The responsibility for WWII lies with the Polish elite who ruled the country in the 30s, who were the first to conclude a non-aggression pact with Hitler in 1934, who were allied to him, who participated in the division of Czechoslovakia with Hitler and who received territorial acquisitions from the Munich conspiracy when Czechoslovakia was surrendered to Hitler.
Historians in the West, in Poland, in Europe, in the USA even earlier have held the point of view that allegedly the Molotov–Ribbentrop Pact initiated the Second World War.
