Don't know what to suggest on a personal or a more general level.

I know that a lot of my friends regard Africa as somewhere we should just seal off, and let them get on with killing each other. Well, that is a bit extreme, but I can see their point as most of Africa does not even remotely conform to western standards.

The ridiculous thing in Zimbabwe is that for years the British government has said it is prepared to pay at least £10M (about 17M US $) to enable the government of Zimbabwe to sell off white owned farms to black people, as long as it is done in an ethical & lawful manner.

Mugabwe is of course still pursuing his campaign that it must be the UK's fault - after all if you are running a corrupt regime, where you are paying bribes to the army, it is a bit difficult to stop. And from what I hear, even if he wanted to stop the cycle of violence, it is too late.

At least the EU renewed its sanctions against Zimbabwe recently, despite French opposition.
I'm afraid that is all you can expect most of the EU to do.
