It would not be possible to invade Zimbabwe except via at least one neighbouring country, and large numbers of Mugabe's very numerous tribesmen and clansmen would in any case fight to the death against any such invasion. For that is what it would be: an invasion. Who has invited us in?
So instead, the Movement for Democratic Change and all other concerned Zimbabweans should issue an appeal to all their fellow-subjects of "Her Majesty Queen Elizabeth II of Zimbabwe and of her other Realms and Territories", to aid them in overthrowing the usurpatious tyrant, Robert Mugabe. Is it conceivable that we would not then go to their aid?
Her Majesty would not have to do anything. That is the point: this would come from within Zimbabwe, and would place moral and political obligations on governments and people in 16 sovereign states (only four of them predominantly, and none entirely, white), and in numerous other territories besides, not only in these islands, but also in the Americas and in the Pacific.
So not only would this rescue the basket case of Africa and make it once more the bread basket, but it would also constitute a formal tie between Africa and her diaspora in the Caribbean. God Save The African Queen!
