I got Sweden, Finland, and Poland to join ME peacefully. Later I invaded Netherlands, and set up a puppet state. Denmark joined from the UoB event, National France joined from the annexation of Commune of France event. Is there a way for the Italian Federation to join ME to reunite Italy? I'm at war with the Internationale (UoB and Syndicalist Italy), and I have +200 relations with the Italian Federation. Also, I gave back the Swiss lands to the Swiss after the war. Will they join ME or remain (supposedly) neutral?
