Are you trying to be equitable or based on power? If it’s the latter then unfortunately no nation in Africa currently has equivalent power.

Australia would be a better option in either case since they are a continent in of themselves and within spitting distance from being a nuclear power after Biden fucked over the French and beat them to a deal for nuclear subs with Australia.

And re: Britain’s nuclear power being controlled by the US. That’s just the maintenance. They still have the nukes and could easily turn to France as the refurbisher if the US denies them. Might even work out as a conciliatory point for the return to the EU that Burnham is harking about.
