It has taken  to long already: the world has been silent and did nothing while the people of Zimbabwe suffered and were beaten up and killed. Why doesn't the UN intervene? It is clear that the African countries are not doing anything and just let Mugabe to trigger a civil war. That won't help the neighboring countries where already millions has fled to (with devasting consequences for South Africa e.g.). Clearly Tsvangirai is the rightfull president.
