One would hope that, at this point, some good might come of the controversial "engagement" approach taken by South Africa and others where African heads of state might indicate to Mugabe that a further crackdown at this point would be unacceptable.
But isn't this the problem? I lean towards engagement policies over isolationism, if for no other reason than the latter doesn't seem to have an end-game to me. But it does always seem that the countries who "engage" with dictatorships, with the purported justification that it gives them more leverage, are never actually willing to step up and put the hammer down. And so we get stalemates like this one.
I guess it's better that someone probably could step up and force an end to the Zimbabwe crisis than for there to be literally nobody the international community could turn to. But that's pretty weak sauce when that someone refuses to step up to the plate.
