Stalin tried until 1939 to woo the Western bourgeois democracies into his Popular Front (which, incidentally, entailed the crushing of the Spanish anarchists and the restoration of capitalism in Catalonia and Aragon to reassure France and England). The West didn't take the bait, and mere weeks after Madrid fell to the fascists in 1939, Stalin decided to cut his losses and make a deal with the Fuhrer. The two tyrants gobbled up Poland on mutually agreeable terms, and Uncle Joe took the Baltics and half Finland for good measure (thereby driving the previously neutral Finns into the Nazi camp). At this point the line of the entire world communist movement (following the Kremlin and Comintern) became pacifist, opposing Churchill as a war-monger when he came to power in 1940 and generally downplaying the Nazi threat. So, contrary to your distortions, Stalin was still upholding Molotov-Ribbentrop in the name of "peace" with Hitler after the British leadership had already repudiated Munich. This treasonous state of affairs continued to obtain until Adolf betrayed his buddy with Operation Barbarossa in June 1941. Then Stalin began aiding instead of slaughtering Polish patriots—although he was sure to hold his armies back at the very gates of Warsaw in September 1944 to give the Nazis time to put down the uprising in the city, sparing the Red Army the trouble! The facts speak for themselves. Go spread your vile lies elsewhere.
