I don't think people realize what's actually happening and there's been more foreshadow than the ones I am going to post but, if anyone is wondering Egghead will be an all out war. Then you might ask me the Strawhats are heavily outnumbered how will the fight the NAVY/WG fleet?
It's simple the answer is 285 chapters back.
The Grand Fleet will take on the marines/wg and they will win. That's what will shock the world.
"Oh but the incident foreshadowed in chapter 800 was The Final War" - Doubt very much, why? The final war will probably be some global shit, with everyone going against the WG, the Grand Fleet would just be more numbers there.
Stussy already warned:
"Emperors have considerable backing behind them."
"A small tiff can flare-up into an all out war."
The Navy is playing their cards as
TOTAL WAR IMMINENT.
The Grand Fleet is promised to cause a great incident
on their own.
