Well, if Katan tries to invade Apulia and the other Central Seas powers backs Apulia up, I would very much expect much the same to happen. Same would have gone for Hyak and the former Exaltations. As well as Jinyi and the Koreas. A Superpower usually can fight a 2 front war against regional powers with some effort and can easily overpower individual targets-depending on the intent of the orders and other stuff like that. That was... sorta my intent . You managed to win the Land war against Kush and the Sea war against the Confederation, but "lost" the desert war.
