Joke.
And yeah, Paradox knows the history but if the German AI loses consistently to the USSR than the game basically doesn’t happen. I guess you could wait for the USSR to roll over Europe and then the Allies become the aggressor but that’s a Cold War game, not a WW2 game. The USSR won 9 out of 10 times early on and it was abortive to the campaign when it happened.
It was a similar problem with the Japanese AI. Back when they would routinely get completely bogged down in China, the Pacific theater would never materialize at all.
I think this strikes a good gameplay balance. The Allies gameplay is to build up to be able to launch and invasion to relieve the Soviets. If they wait too long, Germany might be too powerful to stop. Of course, Germany isn’t always going to win, so there’s still unpredictability.
