There’s also the problem of borders. It makes sense for the people of Wano to not want their borders open (even though this appears to be Kaido propaganda), but there is a logic to it. Why would the World Government not want the country of Wano open?
“An open country lets in ideas that are harmful to the nation,” – to paraphrase Kaido-Ganda.
Now again, looping in Clover: “The idea of the Ancient Kingdom is harmful to the World Government.”
[Sidenote: The Big Lie – The Ancient Kingdom was not destroyed, but was forced into isolation. A deal was struck to preserve the people of Wano as long as they agreed never to leave. A crime on both sides. One crime to delve into the history of said Kingdom, another crime to leave said Kingdom. Cut off from the world, Wano lost its resources and influence and became insular, leaving it ripe to be overtaken by Kaido.]
Before I end, I want to bring in our dear old Professor Clover once more. This is Gomu Gomu no reaching, but in this panel he focuses on the past and confronting history.
Then this panel focuses on Wano’s importance.
In other words, the Wano Kingdom Arc could also be described as “The Restoration of The Ancient Kingdom Arc”, befitting of a battle that affects the fate of the world. Or it could be completely wrong, but that’s how theories be.
