But so long as Mbeki and Obasanjo are not prepared to take effective action against Mugabe, the rest of Africa will do nothing.
I am afraid that a black insurgency will get no active sympathy from outside Zim and as it is landlocked it will get no logistics without such sympathy.
Brit, European or US military intervention will be treated by Africa as neo-colonialism and will arouse opposition and will cause those who might not like Mugabe today to become his enthusiastic supporters in opposition to any such action
Brit intervention worked well in Sierra Leone but the Brits were invited in and even then it had to be under the ostensible purpose of extracting Brit and Commonwealth nationals. Also, Sierra Leone has a coastline off which a Brit taskforce could be stationed from which a Royal Marine Commando could be lifted and a Para battalion could be supplied.
Similar considerations are at work today with the French in Cote d'Ivoire.
But no one in Africa is inviting Brit intervention in Zimbabwe and the nearest place that a Brit taskforce can take station is the Mozambique Channel which is 250 km from the east border of Zimbabwe across the sovereign nation of Mozambique.
It was this anger and resentment which led ZANU-PF to throw the elections.
I have heard on first account that the elite of the party did not expect to survive if MDC came to power.
I expect they had a better chance of retaining their heads prior to the subsequent destruction of the economy, but I won't make any predictions about the outcome any more.
Look what happened in Cambodia, yet Pol Pot and his minions were never brought to justice.
Once again (just as in Uganda) it took an outside force - the North Vietnamese - to push out Pol Pot.
