How much, and what sort of effort will it take to found a faction with members of varying ideologies? For example, say I'm Fascist Italy, and instead of going the historical route with Germany, I want to forge a faction of traditionally Catholic European powers - Italy, France, Franco's Spain, Portugal and Ireland. What exactly does a country need to do to get others on its side, particularly if the alliance is a mish-mash of Fascist and Democratic states like this example?
