That's stupid though, because T'Challa OS the exception
In the comics, and the driving force. To have everyone all of a sudden be all about the rest of the world without T'Challa takes away what made him the GOAT BP of all time. Plus we saw in IW two years after opening Wakanda the idea Okoye had was very minimal in terms of opening the borders and EG when T'Challa was gone Wakanda closed up shop again.
So I highly doubt now for the sequel all these people are going to be pushing forward with Wakandan involvement, this is T'Challas vision, he should be the force behind it, even in the Comics T'Challa is very careful with how much WK is involved with world events and most of the time he isn't putting it in harms way directly minus empyre
