Tehran with Love Achievement

[Literally Me]

Does anyone know what exactly the strategy for this is? It seems that in current game state it's might not be possible.

Play on Non-historical, Germany and Soviet Union must start a civil war so they wouldn't think about Poland. In settings set Poland (to avoid communists or fascists in the government), Czechoslovakia (they can attack Poland, ♥♥♥♥♥♥ up my 1st run), Lithuania (to avoid monarchist civil war) and Romania to historical. As for Iran, play as democrats or Pehlevi. In my successful run I chose his son and conquered Turkey for industry to make a huge army. Then was invited into Allies and waited till 1945.

Thank you, I totally forgot that non-historical is a thing!

I gave this achievement a few tries but it seems to be bugged.
In my last attempt I set the game settings to non-historical in a way so that only Germany and the Soviet Union go their non-historical ways while every other country follows the historical focuses.
Then I waited for both countries to have a civil war or I reloaded. I got around 4 games running until after 1945 this way.

What I observed every game was:
Suddenly Poland gets a surge of Communist or Fascist supporters out of nowhere who start a civil war sooner or later. My guarantee does not matter and I can't support them in their civil war so they flip fascist or communist and when I wait until 1945 the achievement doesn't pop.

And this actually happens when I set the Polish AI to follow the historical focuses while all the others that could influence it negatively like Lithuania or Austria (monarchist paths) are turned off.

I guess you have to reload full non-historical games and guarantee Poland again and again until you get this lucky one in which Poland dominates Europe.

There's also the option that Germany turns democratic and invites Poland when it doesn't have a civil war to its faction which makes it more or less invincible.

But I don't see any legit way to get it done without needing a lot of luck right now.
