Seriously?
New York, LA and Missouri are all part of the same country (have been since California was conquered from Mexico), all speak the same language, have similar levels of social and economic development, and have more or less the same culture. Liberians and Zimbabweans don’t. (Well, I suppose the elite of both countries speaks English, so I’ll give you that).
For that matter, I’d bet that New York, LA and Missouri have more in common culturally than Northern and Southern Nigeria. Let alone two countries at opposite ends of Africa.
