Explore what exactly considering it has 0 relation to the real world?
Except that in England the queen is pretty much powerless while the power of the king in Wakanda is absolute. If you want to compare those two countries you have to compare the election of the prime minister to ritual, possibly deadly, combat with spears and clubs.
Absolute monarchies, the like of which Wakanda has, are rather rare nowadays. So if you want to compare Wakanda to a real world country you have to use Saudi-Arabia (and they do not use ritual combat).
And yes, England also has several archaic traditions, starting with the hostage and ending with the wicks judges wear. Still, such things are inconsequential while the combat in Wakanda not only have far flung consequences, it can also be deadly.
Honestly, it's getting kind of hard to follow your single minded defence of BP which includes defending the practice of choosing the head of state based on how good he is at bashing heads in.
You're just trolling now... aren't you?
