What for? Let's open the history textbook and see the following historical fact: In April 1939, the USSR invited the ambassadors of France and Great Britain to the Moscow talks. The USSR proposed a triple alliance between the USSR, France and Great Britain. Negotiations were held on the basis of the unwillingness of Poland to give the right of passage to the Soviet troops in the event of the outbreak of war. After dragging out the negotiations, the USSR signed a non-aggression pact with Germany. If Poland agreed, it could have been a completely different war, without millions and millions of victims.
For Poland, the USSR was the main threat. Also in 1938, when the USSR announced that it was ready to defend the sovereignty of Czechoslovakia - Poland, denying the right of passage of the Soviet troops and officially stated: in the event of any attempt by the USSR to assist Czechoslovakia, Poland would declare war on the USSR. This fact is enough that the USSR unilaterally withdraw from the Polish-Soviet non-aggression treaty of 1932.
- You can't learn everything.
- See, I didn't know that.
I still don't trust USSR. They were just eating all the nations then, same as Germany.
It'd be interesting to explore a what if, but, if it was on HOI4, I'd say imagine USSR
to pretend to be nice, and then surprise conquer Poland - without Germany help, too.
People said Hitler made an error, by attacking USSR.
But it is a fact that USSR was planning on eating Germany, then the rest of Europe, too.
Come to help but... never ever leave afterwards.
