Oh also, the HK letting the SH be feels like kind of a meme
First of all, why not use them as hostages themselves?
Second, why even fear a war if you're flooding the world anyway?
Lastly, Why would this be the breaking point that starts a "war"? CP0 tried killing Luffy in Wano, in Egghead the Gorosei tried killing the crew, if the SH wanted a war they would have already started it, lol
