Rhodesia was, at one point, the most successful and developed country in all of Southern Africa. The Rhodesian Bush War wasn’t a civil race war. It was a cold war gone hot scenario where communist ZANU forces (lead by the current Zimbabwean leader Mugabe) were repelled time and time again by both Native Rhodesians and Colonial (white) Rhodesians until news outlets like those in America had falsely interpreted the Rhodesian conflict to be racially motivated. The country was forced by the UN to hold an election which Ian Smith won against Robert Mugabe. The UN then forced another election to which the ZANU had threatened to kill native Rhodesians who voted for Ian Smith again. Mugabe won and they held a co-op tp which both Smith and Mugabe had held office, until Mugabe forced him to step down.
Tl;dr, Rhodesia was not a racist regime. Rhodesia has never been a racist regime.
Rhodesia =/= South Africa.
