International law and international organization
In recent times, major powers have disengaged from conflict resolution in areas considered non-core to their interest. In many cases,major powers are unwilling to contribute troops to UN peacekeeping missions (Druckman, and Stern 2000). Some recent interventions by the major powers have been the exemption, and even in these interventions full commitment of ground troops is rare. In the Libyan conflict and the ongoing Syrian conflict, NATO only contributed to by carrying out bombing campaigns.
The increasing condemnation of nations that participate in international interventions is also a major reason for the increasing disengagement. The UN and its backers have been accused of comprising the sovereignty of conflict prone states by intervening (Druckman, and Stern 2000).Conflicting parties are ever keen to highlight interventions as invasion of their sovereign lands by foreign armies. For example, foreign intervention forces in Somalia have been locally branded “infidels”, amidst plundering accusations.
Response to first post
I agree the problem of consensus building is arguably one of the greatest challenges of conflict resolution by International organizations. It is rare for all the nations of an international organization like the UN to agree on the same course of action in a particular conflict (Woodhouse,Miall andRamsbotham 2005). In many instances, there are deep divisions between nations which advocate for intervention and opposing forces. Often, the reasons for opposing or supporting non-intervention are different. For example, the United States was opposed to a military intervention in Syria as the incumbent is an ally of the former. Other nations with trade, political or military ties also block interventions that target their allies.
