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? Furthermore, each of the tribal groups in Zimbabwe should proclaim Her Majesty its Paramount Chief in those same terms.
Her Majesty wouldn't have to do anything. That's 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!
