No list, but there's a general protocol:This has made me curious, what warlords are able to peacefully unite with each other? Is there a list somewhere?
All dems can peacefully reunite with each other.
Batov can reunify with all commies and dems, but draws the line at hard right-wing regimes (excluding despotism).
Commies can reunify with each other, up to LibSoc.
No right ideologies (fascist onwards) can peacefully reunify with each other.
