I guess I am wasting my time here attempting to argue with somebody which has your shocking level of historical ignorance, but anyway. South West Africa was an SA territory, and being invaded out of Angola by Swapo terrorists. SA clearly had an interest in neutralizing a military threat in Angola, therefore. 

What you're not responding to is my point about black people being murdered in townships or dying in cowardly terrorist bombings. The war was here, boet. 

DO try and read some more, especially about history, and not only the back pages of the Sunday newspapers.
