Heard the one about the Polack who started WWII?

Next time you're at a Soviet Embassy party in Poland, ask the Ambassador to tell you about it;

Russian Ambassador Sergey Andreev on Friday described the Soviet’s 1939 invasion of Poland as an act of self-defense, not aggression. The comment prompted Poland’s Foreign Ministry to declare Saturday that the ambassador “undermines historical truth” and seems to be trying to justify Stalinist crimes.

World War II began after Nazi Germany and the Soviet Union sealed a pact in 1939 that included a secret provision to carve up Poland and other parts of Eastern Europe. Germany soon invaded Poland from the West, followed by a Soviet invasion from the east 16 days later. Millions of Poles were killed in the war.

It made sense to Lillian Hellman, Dalton Trumbo and John Howard Lawson.
