Though IGAD and the ICU met and published a cordial and formal communique committing the ICU to the IGAD plans on 2 December, by the time United Nations Security Council Resolution 1725 was passed on 6 December, the ICU was openly and militantly opposed to peacekeepers entering Somalia, and vowed to treat any peacekeepers as hostile forces. Because of regional divisions, there were also UIC resistance to allowing Ethiopian troops be part of the mission. Ethiopia, for its part, was leery of allowing Eritrean troops to be members of the IGAD peacekeeping force.
