Best thing to do is let other nuisances do it for you. Like propagating a world war. Propaganda is your greatest weapon; a fascist named Hitler used it. Make sure the war eliminates the strongest country, or create one during the war, only to destroy them later so your entry will be a little easier. Tip the momentum of the war in favor of the stronger country and then assassinate their leader, label him a fascist and lay down better living conditions for his countrymen. At the same time get closer to the lesser countries, they will be too drenched in victory to realize your gradual inclination to power, then ultimately unite them under a treaty of some kind or cite economic dependency. What you can do with propaganda is endless. Just remember that madness is an exception in the individual but a rule in group. A lesson in the abyss of propaganda
