You think 3 SN + sanji + zoro + killer + retainers will take down kaido and BM + commanders + vets + numbers + flyers?
You are underestimating An Emperor just like y all did during WCI,
here we have 2 emperors , both can control the weather too.
You really think Navy wont come?
Wano war will be greater than MF ,
Of course Navy is coming.
Oda never said in a month luffy and co will win but via Hawkins, their chances of survival will be low.
Especially seeing BM presence too.
Wano is gonna last 6/7 weeks, we are already 2 weeks , 2 more left according Hawkins predictions, then 2 more to have another full moon.
