WASHINGTON The last time American diplomats locked a group of prospective founding fathers in a room with orders not to come out until they had a constitution was a decade ago, in Dayton, Ohio. The founding fathers in question represented Bosnia's Muslim, Roman Catholic and Orthodox Christian communities.Like the current efforts in Baghdad, the negotiation in Dayton went into overtime. In the end, that conference succeeded in arriving at a settlement that ended the fighting in Bosnia, but failed to produce a workable arrangement for the governance of that nation. As a result, 10 years on, Bosnia continues to be a ward of the international community, secured by an international peacekeeping force and governed by an international proconsul.
