Thank you for the response! It's really nice seeing people enjoy my work

These are some really great suggestions, and though some of them are a little bit too complex given my current (lack of) modding capabilities, I'll definetily keep these in mind as I improve.

Diplomacy modding in particulor is one of those things thats quite confusing to understand. I had originally intended for alliances to form via a button in the diplomacy menu, with AI nations being more likely to form alliances between each other if they aligned in terms of ideology, but this all turned out to be a bit complicated to program. Though I will definetily return to that idea someday.

As for spreading the revolution, base ET currently has casus bellis called "Spread Communism" and "Spread Fascism", which I modified to make it so losing nations also enter into a faction-alliance under the winning nation (if a new government is installed). So while it is very basic, it's still there to some extent. (Though admittedly I haven't bug tested this feature at all, it might be completely broken for all I know lol).

I come back after several months: the mod is progressing very well, i hope the Extended Timeline will adopt this submod as canon because it's really the best mod that try to emulate the post 1700 timeline.

I don't know if it will be possible but adding and intrigued faction system to the socialist government/ fascist/nationalist dictatorship with events may be the last step to complete the political rework.
But i don't know how much moddable is, so... You are doing great, still thank you for your mod.
