Rhodesians knew Britain was going to turn over the management to blacks (as the did in Uganda & Kenya), so they acted; they certainly never preferred to fight the war alone, but saw that as the only alternative.
I’m not sure why that is hard to understand; there is hardly an axe to grind. Britain did the same thing in their African and Asian colonies, and is attempting to in its Northern Ireland colony (which is no longer an industrial powerhouse, but rather a population on the dole). If more white Brits had moved into other colonies, that scenario would have played out all over.
You don’t know how white rule can be maintained in a country that is 95% black. “turning over management to the blacks” - or respecting the wishes of the people as those who believe in democracy call it - was inevitable.
So instead of living in reality, its a good way for you to bash the nasty Brits. Who wouldn’t have been there at all if it wasn’t for colonialism. Something which Americans are not in support of remember. So many logical flaws in your posts its pretty amazing. Keep on replying, and i’ll look forward to helping you with them.
