now lets get back on topic shall we? now, I can argue that the romans could of only stop the expansion of the Samnite League by intervening at the start. Yes, I mean the invasion of the Sidicini. It can be that the Campani could of tried to protect the Sidicini, and would of been beaten by the Samnite league. Then the Campani would go to the roman senate to beg for them to intervene in the war on the Campani side. The Romans, being those manipulative and ambitious scum that they are, would say that they would not do so because of their treaty with the Samnite League. This would force the Campani to surrender their lands, including the city of Capua, the most opulent city of the Italian Peninsula at the time. The romans would ask the Samnite League to stop attacking Campania. The Samnite League would refuse, and war would be declared. If the romans won the war, the Samnite League's lands would of been severely damaged due to pillaging, not to mention what would happen to the stability of the Samnite League . Not only that, the romans would of only gotten stronger from that, they would have the rich lands of the Campani, it could of also stabilized the Latin League. Due to the fear of retaliation by the romans if the members revolt or try to become independent. The Romans also could of taken the place of the Caudini tribe of the Samnite League. As in unite the Italian Peninsula. It would take 2 to 3 more wars to take over the Samnite League of course. But I don't know if the romans could take over the Mediterranean though. But they would need to drop the republic government to rule over the place for over a year.
