Invasions take months of planning. The Nazis were planning on invading not the soviets. The molotov-ribbentrop pact was signed 2 weeks before the Nazis invaded and signed 1 week before by the supreme Soviet.

Of course I’m sure you would’ve rather all of Poland go to the Nazis when they capitulated.

No they literally did not. The molotov-ribbentrop pact is declassified you can go and read it. It said nothing about a joint invasion.

A month after invading Poland together

They did not. Germany invaded Poland and poland capitulated and the government went into exile. Then, the Soviets entered the former Polish territory to prevent it getting into the hands of the Germans.

Nazi Germany and Soviet Russia signed the “Nazi–Soviet Boundary and Friendship Treaty”.

Having “friendship” in the name is not an alliance either.

It was not a literal alliance it was a non-aggression pact. You can go read it yourself.

A non-aggression pact is not the same thing as an alliance.

The guys that did a genocide care about human rights?

Why did you hentai censor the swear word?
