Annan had already decided not to get involved long before Clinton. The death of the Belgian peacekeepers (where your Clinton involvement timeline begins) was already well into the disaster that Annan had watched unfold. It's not that Clinton is free of any blame on this, but that Annan could have nipped the problem in the bud before it grew beyond anyone's control. Of course he was promoted for his disservice both in Rwanda and Kosovo, such is the nature of the UN.
So, do you think Bush will be responsible for any massacres in Haiti?
