The liberal democracies of Europe made similar agreements with Hitler before the USSR, and shot down Stalin's suggestions of an anti-fascist alliance. Furthermore, US industrialists were directly inspired by Fascist Germany and Italy to carry out the failed Business Plot against FDR. The USA also paid reparations to German industrialists for their destroyed property after the war was over (Yes, even German industrialists who used Holocaust slave labor, like Krupp).

Stalin with regards to this said:
"Indeed, it would be ridiculous and stupid to close our eyes to the capitalist encirclement and think that our external enemies, the fascists, for example, will not, if the opportunity arises, make an attempt at an attack upon the USSR. Only blind braggarts or masked enemies who desire to lull the vigilance of our people can think like that."
Even the US state department confirmed Stalin's rationale for a pact with Hitler
"The Soviets signed the Molotov-Ribbentrop Pact with Nazi Germany after the British and French rejected Soviet offers to establish a military alliance against Germany"

Doesn't matter for the libs; ultimately, they both invaded Poland and they took photos of each other smiling and celebrating after meeting halfway across Poland with swastikas and hammers and sickles side-by-side, something the other nations didn't do, so no matter how complex the situation may have been, that's the bit that will stick
don't care, I'm documenting history instead of forgetting it. Liberals demand we forget history or else be deemed with some dreaded nonsense epithet. "Tankie" or "Stalinist."
also, from one of these articles "Poland, whose territory the vast Russian army would have had to cross to confront Germany, was firmly against such an anti-fascist alliance." So you can see how the annexation of Poland's territory was the outcome of refusing to let the USSR cross their territory to fight Nazi Germany earlier. What you refer to as smiling and celebrating was an uneasy truce at a newly established front line which lasted less than a year. The USSR wanted to pack up the factories and move east to slow down what would become Operation Barbarossa, but neither the Polish nor the Finnish would allow cooperation with the USSR.
