On last weeks Question Time, this was put to the Labour panelist, could be wrong, but I think it was O'Brian, he said that regardless of what Mugabe does, he was elected, so we can't interfere. Thats Labours stance anyway.
because of our imperial past in the region, we can't militarily intervene, but I think Nato as a whole, should encourage, maybe with bribes, the neighbouring countries to take action.
The one thing that is blatently clear, is that Mugabe should be deposed.
