Let's remember WHY the WG/Marines never invaded Wano to begin with:
A: Kaido
B: The Samurai being an unknown factor (along with Oden's legacy with Roger and Whitebeard falsely inflating the strength of Samurai in the WG/Marines eyes)
We are no longer living in this era of uncertainty: Aramaki kicked the fucking shit out of the Scabbards, with only Yamato doing AAAAAANYTHING to him (don't bring up Momo like the the FUCKING LYING LEAKERS).
Kaido is long gone
And Green Bull just proved he can low diff the Red Scabbards without really trying.
The Marines have nothing to fear regarding Wano's Samurai presence, and the country's security is so bad that Who's Who is out here stealing Katana's and shit from randos.
The Marines should be heading to Wano soon, especially with Elbaph being attacked. The WG is trying to get ahead of the pirates by controlling the end of the Grand Line, to keep people from reaching Lode Star.
Also, if the Gorosei know about Pluton, which I think they do:
Expect for them to move on Pluton when Teach does, after learning of Pluton from Caribou.
Since, when Teach learns of Pluton from Caribou, a certain spy for Sword will call up the WG, and tell them...
"Hey, Sakazuki... bad news. Blackbeard is attacking Wano... for Pluton."
