What if the USSR had lots of Satellite States in WW2? - HOI4 Timelapse

I don't like it when Japan bugs and does not submit to Communists

In this case, the Communists did not have access to the largest reserves of Tungsten. Without deposits of Tungsten and the ability to buy it normally, the Comintern could not make jet planes. In the video, the Comintern lost from the beginning in the air, and then on the ground. This is the worst limitation for the Comintern in the game.

Yea I was surprised myself. I think a lot of the puppets were limited and were not able to put out their full potential.
