It really boils down to two questions:
1) Do you think the western countries that lead the world over the past century (like my one! USA! USA!🇺🇲🦅) can continue to lead the world over the next century without African resources?
2) Do you think any developed countries over the next century can continue to secure African resources through theft, conquest, and colonialism, or will they have to secure them through diplomacy?
The answer to 1) is a resounding "no." But 2) is less clear. Maybe?
