What Does the UN Do for Peace and Security?

The United Nations (UN) is an international organization established in 1945 with the primary goal of maintaining international peace and security. Since its inception, the UN has played a central role in addressing global conflicts, promoting diplomacy, and establishing norms and institutions to prevent war and violence. The UN's efforts in the realms of peace and security span conflict resolution, peacekeeping, humanitarian assistance, disarmament, and international law. This article explores the various ways in which the UN contributes to global peace and security.

The UN's Role in Peace and Security

Mandate for Peace and Security

The UN's core mandate for peace and security is outlined in its founding document, the Charter of the United Nations. The Charter established the framework for international cooperation, emphasizing the promotion of peace, security, and human rights. According to Article 1 of the Charter, the main purposes of the UN are:

• To maintain international peace and security.
• To develop friendly relations among nations based on respect for the principle of equal rights and self-determination of peoples.
• To achieve international cooperation in solving international problems of an economic, social, cultural, or humanitarian nature.

The UN Security Council: The Main Body for Peace and Security

The UN Security Council is the principal body responsible for maintaining international peace and security. It is charged with identifying threats to peace, authorizing peacekeeping missions, and imposing sanctions or military action to resolve conflicts. The Security Council consists of 15 members, 5 permanent members with veto power (China, France, Russia, the UK, and the USA) and 10 non-permanent members elected for two-year terms.

Key Responsibilities of the Security Council

• Conflict Prevention: The Security Council works to prevent the outbreak of conflicts by addressing the root causes of violence, such as political instability, poverty, and human rights abuses. It employs diplomatic measures, including special envoys, mediation, and sanctions, to resolve tensions before they escalate into armed conflicts.
• Peacekeeping and Peacebuilding: The Security Council authorizes peacekeeping missions to provide stability in post-conflict regions. These missions are designed to support the implementation of peace agreements, protect civilians, and assist in rebuilding national institutions. Examples of peacekeeping operations include the missions in Cyprus, South Sudan, and Mali.
• Sanctions and Military Action: The Security Council has the authority to impose sanctions on countries or groups that threaten peace, such as economic embargoes or travel restrictions. In cases of severe threats to international peace, the Council can authorize the use of force through military interventions, as seen in the Gulf War (1990-1991) and the NATO-led intervention in Libya (2011).

UN Peacekeeping Operations

What Are Peacekeeping Operations?

UN peacekeeping operations are deployed to areas affected by conflict to help maintain peace and security. These operations are typically authorized by the Security Council and are composed of military personnel, police officers, and civilian staff. Peacekeepers are tasked with monitoring ceasefires, protecting civilians, supporting the delivery of humanitarian aid, and assisting in the implementation of peace agreements.

Principles of UN Peacekeeping

• Consent of the Parties: Peacekeeping operations are deployed with the consent of the parties involved in the conflict. The UN does not intervene without the agreement of the governments or conflicting parties, ensuring that peacekeeping efforts are seen as legitimate.
• Impartiality: Peacekeepers must remain neutral and impartial, without taking sides in the conflict. This helps ensure that all parties can trust the UN's role in conflict resolution and peacebuilding.
• Non-use of Force Except in Self-defense: UN peacekeepers are mandated to use force only in self-defense or to protect civilians from imminent harm. Their primary role is to support political processes and maintain stability, not to fight in the conflict directly.

Notable Peacekeeping Missions

• UNIFIL (United Nations Interim Force in Lebanon): Established in 1978, UNIFIL's mission is to monitor the cessation of hostilities between Israel and Lebanon and assist in the implementation of peace agreements.
• MINUSMA (United Nations Multidimensional Integrated Stabilization Mission in Mali): Launched in 2013, MINUSMA aims to support the stabilization of Mali following the outbreak of conflict between government forces and armed groups in the northern region.
• MONUSCO (United Nations Organization Stabilization Mission in the Democratic Republic of the Congo): Operating since 1999, MONUSCO focuses on protecting civilians in conflict zones, supporting the Congolese government, and facilitating humanitarian aid delivery.

Conflict Resolution and Mediation

Diplomatic Tools for Peace

The UN employs several diplomatic tools to address conflicts and promote peaceful solutions. These include:

• Mediation and Negotiation: The UN often sends special envoys or mediators to facilitate dialogue between conflicting parties. These mediators work to build trust, propose solutions, and help parties reach agreements. Notable examples include the mediation of peace agreements in the Middle East, Colombia, and Sudan.
• Peacebuilding: The UN supports post-conflict recovery by helping countries rebuild political, economic, and social institutions. Peacebuilding efforts involve providing technical assistance, encouraging national reconciliation, and fostering the development of a functioning government and civil society.
• International Law: The UN promotes the rule of law as a foundation for peace and security. International treaties, such as the Geneva Conventions and the Arms Trade Treaty, set legal standards for the conduct of warfare, humanitarian protection, and arms regulation.

Human Rights and the Protection of Civilians

Human Rights as a Pillar of Security

Human rights are integral to the UN's efforts to maintain peace and security. The UN recognizes that violations of human rights, such as genocide, ethnic cleansing, and mass atrocities, often lead to instability and conflict. As a result, the UN works to prevent such violations through advocacy, legal frameworks, and international cooperation.

• Human Rights Council (UNHRC): The UNHRC works to address human rights violations and promote the protection of fundamental freedoms globally. It holds regular sessions where countries report on their human rights practices and address emerging challenges.
• International Criminal Court (ICC): The ICC, supported by the UN, is responsible for prosecuting individuals responsible for genocide, war crimes, and crimes against humanity. It aims to hold perpetrators accountable and deter future violations.
• Protection of Civilians: The UN's peacekeeping and humanitarian operations often include mandates to protect civilians caught in conflict zones. This may involve physical protection, humanitarian aid delivery, and the monitoring of ceasefire agreements.

Disarmament and Non-Proliferation

Efforts to Prevent the Spread of Weapons

The UN works actively to prevent the proliferation of weapons of mass destruction (WMDs), including nuclear, chemical, and biological weapons, through disarmament and non-proliferation initiatives. These efforts are aimed at reducing the likelihood of catastrophic conflict and ensuring international stability.

• Nuclear Non-Proliferation Treaty (NPT): The NPT, established in 1968, aims to prevent the spread of nuclear weapons and promote disarmament. It has been signed by nearly every country in the world and is a key framework for global nuclear security.
• Comprehensive Nuclear-Test-Ban Treaty (CTBT): The UN supports the CTBT, which seeks to ban all nuclear explosions for both military and civilian purposes. The treaty has yet to be fully ratified but remains a key goal in the effort to prevent nuclear proliferation.
• Biological and Chemical Weapons Conventions: The UN works with the Organization for the Prohibition of Chemical Weapons (OPCW) and other organizations to eliminate the use of chemical and biological weapons globally.

Challenges and Limitations of the UN in Peace and Security

Challenges Faced by the UN

Despite its significant role in global peace and security, the UN faces several challenges in fulfilling its mandate:

• Veto Power in the Security Council: The five permanent members of the UN Security Council (the U.S., Russia, China, the U.K., and France) hold veto power, which can block decisions on critical matters, including military interventions and sanctions.
• Limited Enforcement Power: The UN often lacks the authority to enforce its resolutions, relying on member states to implement decisions. This limits the UN's ability to take decisive action in certain conflicts.
• Complexity of Modern Conflicts: Many modern conflicts are not purely interstate wars but involve non-state actors, terrorism, and civil wars, making peacekeeping and resolution efforts more difficult.
