Meh...almost all of Europe signed non-aggression pacts with Germany prior to WW2, including Poland in 1934. A fact which almost always get forgotten by Western propagandists.
Japan is a single nation which honored her non-aggression pact.
Uhhh, I think the world knew a lot more about Hitler in 1939, than they did in 1934, don'cha think?
Nice try comrade but you “forgot” that “almost all of Europe” didn't sign a secret protocol dividing a large part of Europe between them and “Nazis”, didn't invade half a dozen of countries, didn't send millions of people from those countries to concentration camps in Siberia and didn't supply “Nazis” with millions tonnes of natural resources when they were launching Auschwitz.
