If you went to Doha this summer, you may have seen some militiamen from Chad. Perhaps at breakfast. For the last few months, 300 downtrodden tribesman, disaffected politicians, and madmen with guns have been staying in the city’s Sheraton Grand hotel, negotiating peace with the Chadian government. Three weeks ago they signed a ceasefire and now, having supposedly agreed not to kill each other, they are back in Chad’s capital, N’Djamena, trying to organise elections.
