That's actually a pretty good point, would make sense too. The marines are about to basically go to war with Luffy afterall.
The World Govenment is totally out for his blood now. Luffy's subordinates infiltrated Mary Geoise during the Reverie, and attempted to assassinate a Celestial Dragon, then bragged about it afterwards to the people nearby (LOL Leo and Sai are madmen). Between this and the Sun God Nika Fruit, the Gorosei KNOW they have to take out Luffy, NOW. No more fucking around.
Fishman Island, Alabasta, Wano, and possibly Dressrosa are all in some hot shit right now.
Regarding CP0, the former CP9 members were also focused on securing what? Pluton. Reintroducing former CP9 characters after revealing Pluton's existence in Wano means they're going to get involved with it, again, IMO.
