Making AMITY Better (And Ourselves Rich And Powerful)
We should try and seal as many trade deals with as many clans in different villages as possible. And get as many summoners to join the summoner trade network as possible. Massive amounts of trade between villages will cement this alliance and take it from something that could fall apart any second to something that will live on and truly become the basis for how geopolitics is done.
AMITY as it is doesn't really have much to facilitate negotiations between villages. If one village is mad at another for doing something, and the other doesn't want to stop, negotiation without war can only get them so far. Trade, and sanctions/tariffs, will naturally fill in that gap. If things go well, we'll be able to negotiate with other villages by using trade as leverage, just like irl sanctions are being used against Russia. And the Gōketsu can make sure it gets to that point by establishing as many trade deals as possible, as fast as possible.
Being the major Leaf hub for trade with other villages will also give us lots of money and political power. Trade with every village will boost the Gōketsu's income back into 'not quite able to buy a small country' range, for one thing, and quite possibly into the 'Ooh, Grass is looking pretty cheap' range. And whenever Asuma wants to sanction another village or increase tariffs against one to increase pressure on them? Guess who he'll have to negotiate with first. That will give us enormous political power, on the level that Tsunade or Naruto hold right now. After all, if AMITY works then the equivalent of war won't be waged by S rankers, it will be waged through trade deals and tariffs. That makes the International Trade clan the most powerful people in the village.
With that kind of power, we could negotiate for scrolls, do as much uplift as we want, make sure that Akane et al won't need to go on dangerous missions, focus on killing dragons, and have plenty of time to FOOM without worrying about being killboxed or something. And then we can expand. This only covers the villages in our general section of the EN. Someone is going to need to go to Bear and get them to join. Who knows what's beyond the EN? This will give us the breathing room to go exploring, and punch new and interesting things!
