Scenario: South Africa has taken over Lesotho and Swaziland. They begin an invasion of Namibia. Does South Africa successfully take over Namibia?
I'm surprised that haven't just taken them over. I know it's tribal but even then just give them more autonomy when you take them over. So, yes they would win and I would be interested to see how it would play out.
South Africa has a decent army. They got enough power to take it I would assume.
