Just out of curiosity, I compiled a list of the countries involved in the Rhodesian (or Southern African) War and their populations. ....
This war could be similar to the Sino-Japanese War in that it will not matter how many battles the NRA wins, the other side will just refuse to give up, especially when they keep getting Soviet weapons, funds and advisors, like the Cubans. And meanwhile the bodybags keep piling up, the economy continues to deteriorate, more and more areas in Rhodesia become "no-go" areas for Whites, the Black South Africans get more and more restless...
The numbers are against them, and logically they should make some sort of peace with that as they did OTL. ITTL hotter heads have prevailed. Of course they might be figuring to change those odds a little with the use of WMD -- but that too will get messy.
The situation kind of reminds me of a "gotcha moment" that Hitler had when the British and French went against his expectations and declared war over Poland -- suddenly he had what he didn't expect on his hands.
I have no doubt that there will be dissent in Salsbury and Pretoria, but as the situation becomes more desperate, dissent will be seen more and more as treason.
Thanks for the research John.
