Problem: The United Nations is often criticized for its inability to stop states from using military force. While it is true that the United Nations cannot force states to comply, it can raise the costs associated with using military force when the use of force is not sanctioned by the United Nations. Which of the following best describes how the United Nations can affect the costs of unilateral uses of military force? While the United Nations cannot forcibly prevent states from using military force, UN approval often leads to greater burden sharing, thereby reducing the economic and military costs associated with the use of military force. The United Nations can use its own military forces to stop states from engaging in acts of aggression, thereby raising the potential costs of a conflict. United Nations approval of military operations means that troops used in military operations will come equally from each member state. Accordingly, a lack of UN approval means that one state will always shoulder more of the burden. The United Nations can impose sanctions without member-state approval, thereby increasing the costs of taking action. Need Assignment Help?
