You are right, this cleansing is only within their borders...

Brilliant country with a lot of potential. Psychotic leadership - it's far worse and more violent than a lot of people realise. (As in - throwing dissenters down mine shafts violent.)

The West is partly to blame. Mugabe and Zanu-PF aren't going anywhere while Zim remains a cheap under-the-counter source of diamonds and minerals.

Rhodesia was run as a segregationist society on ever level. But if you want to change that, you don't just wall off the people, throw a knife in the pit, and declare that the strongest survive. Which is exactly what we did. Both sides were forced to wage all kinds of guerilla warfare in an attempt to survive. It is no surprise that a brutal, corrupt leader like Mugabe emerged. They were the only ones that would survive such a challenge.

Rhodesia was a productive state with a developed economy. After Rhodesia became Zimbabwe, decades of progress was undone. The new regime essentially just looted the country for themselves. Everyone there is worse off now! Worse yet, the segregation of blacks was just replaced with the segregation of whites via 'land redistribution' schemes.
