why did apartheid last so long

the whites went from a sizable minority to a tiny minority in 80 years... other african countries could supply the sa blacks with ak47s rpgs mortars what would they need more to overthrow the whites... its easy to recognize the enemy... the color of their uniform is the color of their skin... yet they didn't, the whites gave up themselves... i really don't understand this

And when it wasn't the US or the USSR, it's the World Bank. (hint: when a loan shark insists that your schools are insignificant and you should spend no money on them, he's not on your side)
