Even with all that you named......it's fall under having a strategic and logistical long-term plan to keep such a ""institution"" going for so long, that even till this day we are still feeling the repercussions
It's only nature to want to defend yourself and raise up under the oppression of getting kicked. But retaliating and making your "presence known" shouldn't have to be a suicide mission. That's all I'm saying.
And yeah, T'Challa seeing the problem his elders created was growth on his part.
But NEVER in the movie did he give away anything. I see folks saying this...that's just disingenuous and a gross mischaracterization of what actually happened.
As King and Head of State of his nation....T'Challa went to U.N to make his ""presence known" and to announce to the world and it's leaders that Wakanda was NOT the poor,poverty stricken 3rd country it presented itself as. But instead was a powerful and highly technological advance nation
Wasn't THAT what Killmonger ultimately was trying to do?
