THE PEERLESS ADVANTAGE OF UN PEACEKEEPING

UN peacekeeping is one of the most important tools at the UN’s disposal for conflict mitigation and stabilization. Peacekeeping operations are authorized by the UN Security Council, where the U.S. has long used its position as a permanent member to advocate for strong, clear peacekeeping mandates to effectively meet the world’s evolving security and civilian protection challenges.

At one-eighth the cost of U.S. military operations, UN peacekeeping provides stability in crisis zones key to U.S. national interests but often out of the public eye. In the Democratic Republic of Congo, home to the world’s richest critical mineral deposits essential for U.S. technological dominance, the UN has successfully prevented a relapse of one of the world’s worst conflicts since World War II, in which more than six million civilians were killed. In South Sudan, a Christian majority nation that separated from an authoritarian Islamic regime with bipartisan U.S. support, the UN supported the creation of an independent state in the heart of the strategic Nile basin. In Somalia, where terrorism and piracy threatens maritime shipping lanes critical for U.S. commerce, the UN has contained threats to international security. In disputed Kashmir, a flashpoint for rival nuclear powers who are both significant security partners for the U.S., the UN has successfully sustained deconfliction for decades.

In every case, as a permanent member of the UN Security Council with veto power and unique political capital, the U.S. has an outsized voice in globally shaping every UN mission on the ground while paying a fraction of the cost – roughly equivalent to what the U.S. spends on the defense of Guam each year. That’s why both Republican and Democratic presidents and lawmakers have long acknowledged the value of UN peacekeeping to U.S. national interests.

Women in Peacekeeping

Women in Peacekeeping

Women are deployed in all areas of peacekeeping – police, military and civilian – and positively impact operations. While the number of women in uniformed positions has grown over the years, the UN is actively increasing their representation. By 2028, they aim to have women comprise at least 15% of military, 25% of military observers and staff officers and 20% of police units.

The Security Council has also adopted ten resolutions since 2000 –  many introduced by the U.S. – supporting women in conflict prevention, peace and security and advancing human rights.

Protection of Civilians

The protection of civilians (POC) is an essential part of many peacekeeping mandates that authorizes missions to take any necessary means – including deadly use of force – to prevent, deter and respond to threats of physical violence against civilians. In most cases, the ability to use that force must be explicitly granted by the host country. POC activities require coordination among civilian, police and military components of a mission. Since POC mandates were established by the Security Council in 1999, the Council has launched 16 such operations, which are strictly guided by the Department of Peace Operations POC policy.

Ceasefire

Ceasefire Monitoring

Leveraging the impartiality of UN peacekeeping, ceasefire monitors observe ceasefire arrangements, accurately record and report incidents and mediate among parties. Observers can be deployed to monitor a truce, cessation of hostilities or ceasefire agreements. These may involve demilitarized and temporary security zones, as well as military cantonment arrangements.
Eight missions currently have ceasefire monitoring within their mandate, including UNIFIL (Israel and Lebanon), UNMOGIP (India and Pakistan) and MINURSO (Western Sahara).

PKO Election Assistance

Election and Security Assistance

Elections are a critical transition stage from conflict to peace and often a milestone for the strategic drawdown of international support. UN electoral assistance ensures a secure environment for credible elections and can include technical assistance to national election commissions, support to national police and authorities responsible for a security context for free and fair campaigning, panels of experts, electoral observation and operational support to international observers. Since 1991, the UN has responded to the requests of 115 countries to assist with elections.

PKO Human Rights

Human Rights Reporting

In the world’s most repressive crisis zones, UN human rights reporting is often the only public source of credible information on atrocities. Monitors provide evidence of rights violations to the Security Council, support early warning mechanisms through monitoring and data collection and advise government and local actors on institutional reform to build national capacity and strengthen domestic accountability. Current missions with human rights components include MONUSCO (Democratic Republic of Congo), MINUSCA (Central African Republic), UNMISS (South Sudan) and UNMIK (Kosovo), as well as political missions in Afghanistan, Haiti, Iraq, Libya, Somalia and Sudan.

PKO SSR

Security Sector Reform

Security sector reform (SSR) is an essential part of UN peacekeeping operations, particularly in post conflict settings, and enhances capacity and responsible governance structures in the security sector of states confronting threats to international peace and security. Disarmament, demobilization and reintegration (DDR) involves transitional weapons and ammunition management initiatives and the reintegration of former combatants into national armies and civil society following cessation of hostilities. DDR activities have been an important element of peace processes. Since 1989, more than 60 UN missions have been tasked with conducting such activities.
