Black Panther: 13 Biggest Unanswered Questions
10. How Many Spies Does Wakanda Have Worldwide?
The Question: It's mentioned several times during the movie that Wakanda has spies embedded in every nation on Earth, with Killmonger ordering the most compliant cells in London, New York and Hong Kong to be activated. So, how many Wakandan agents are actually stationed around the world?
The Likely Answer: In the comics, Wakanda's population is estimated to be around 6 million, and assuming only a small percentage of these people are spies (as is the reality in every nation), it probably doesn't leave room for more than a few thousand of them at most to be installed around the world's 195 countries.
Even if we say 10,000 spies total, that'd only be around 50 spies per country on average, which isn't exactly a lot if Killmonger plans to decisively overthrow the world's superpowers. All that Vibranium weaponry will help, but still.
You can argue that the social structure of Wakanda perhaps allows for a greater percentage of their population to be espionage agents, but credibility really starts stretching at this point.
