It is a truism familiar to peacemakers: that the solution to an ethnic conflict is drawn long before the parties are willing to accept it. In Northern Ireland, the solution was sketched 20 years before the Belfast Peace Agreement. In Bosnia, the contours of a solution—one that the international community could force upon the warring parties—were discussed even before the war broke out. In Sudan, the solution was mooted 30 years before the Comprehensive Peace Agreement.
