Send in the Mercenaries

SO THE UNITED STATES has brokered a cease-fire among the warring factions in Darfur, and the U.N. Security Council has authorized the deployment of a peacekeeping force. To anyone blissfully unfamiliar with history, this sounds like a decisive step that will finally end the violence that has left at least 200,000 dead and 2 million homeless.

Alas, this is not the first cease-fire agreement in Darfur. An accord was reached in 2004 and was immediately violated. There is no reason to think that the current treaty will fare any better, especially because one of the main Darfur rebel groups has refused to sign it.
