I wonder if the Government would be happy with this fight or not.
Either Kaido and Big mom alliance that scared them a lot will be broken, or the pirate captains Kidd, Law and Luffy will save Wano from Kaido, and they will free Wano country, and open their borders, and those strong Wano samurai will be Kidd, Law and Luffy's allies instead, remember Akainu and Kizaru were afraid of Wano samurai.
Either way, the Government will lose again unless the both sides doesn't kill each other at the same time.
