Slavery ended not because the white man intended to free slaves but because machines were invented which did the work that slaves hitherto did, and keeping slaves became more expensive than using these machines.
So, if a time ever comes when human labour is required en masse to do jobs that machines cannot do, the white man would invade Africa again and enslave the continent. When that happens, we are nothing but sitting ducks.
Only the threat of mutually assured destruction can prevent this from happening. Which is why Africa must build núclear weàpons like the future of our continent depends on it, because it actually does.
It is better to build a weapon that we might never need than need them one day and not have them.
If we don’t, our children will ask what we did to protect their future.
