User blog:Mr. Strongworld/one piece world at war

I was thinking about the huge war that was said to involve the whole world when someone gets to mariejois, right?? and i saw through the WB-war chapters again and i was thinking something similar, only a lot more elaborated, with longer fights, more strategies, and a lot of killing. this will probably be one of the last things in one piece to happens, and i know that trying to predict something like this is very difficult but please, try and give me your opinions.

Who will be killed?

who will participate?

What is going to be the results?
