The U.N. and France are negotiating what appears to be the departure of the defiant incumbent president, Laurent Gbagbo. He refused to step down after losing re-election in November. Since then, his supporters have engaged in a deadly duel with forces backing Alassane Ouattara, the internationally recognized winner of that election. Monday, U.N. airstrikes backed by French firepower ratcheted up the pressure on Gbagbo, leading to Tuesday talk of a ceasefire and his negotiated exit.
