I’m inclined to agree, but it would be “racist” and “colonialist” and god (Karl Marx) forbid that.
That's why China will do the colonial intervention this time. This will be lauded as "one developing nation helping another."
I would like nothing better than to sort Mugabe and his clique out, but that won’t work either. How on earth can there be military intervention in Zimbabwe? There are no bases within thousands of miles. How would we get an army there? It’s a land-locked country - we couldn’t do a d-day type landing on the beaches. We’d need permission from one or more of the neighboring countries to move troops through them. That would take weeks to do, even if we could get them to agree to it. Mugabe would have all the time in the world to prepare, both his army and to yell “neo-colonialism” at the top of his voice, and there’s plenty of fools who would believe him. If we couldnt get permission to move through Botswana or Mozambique or wherever, it would have to be done by paratroops - the initial attacks would have to be anyway. But that would mean having to move all the troops, all their reinforcements, arms, ammunition, fuel, supplies by air, over thousands of miles. And we’d have to get permission to overfly half a dozen countries airspace. Supposing they refused? Supposing they agreed, but then, under pressure from Mugabe or the OAC, withdrew their permission half way through the operation? We could end up with a battlegroup stranded in the middle of Africa. It doesn’t bear thinking of.
The only ending I can see to this is if things continue to deteriorate in Zimbabwe, eventually folk will vote with their feet and leave. Once the problem begins to be exported to the neighboring nations, then they will have to take action.
