Media headlines often make it seem as if peacekeeping is not going well; they tend to highlight violence, displacement and abuse. The quantitative data, however, tell a different story. Peacekeepers are saving lives and helping to keep the peace.
I have studied peacekeeping since the early 1990s, when I worked at the United Nations in New York during the devastating failures in Somalia and Rwanda. I have since applied a scholarly lens to peacekeeping – examining all cases, not only failures – and found that more missions were succeeding than failing. I have also witnessed peacekeepers in action in a variety of conflicts in Africa, the Middle East and Europe.
The narrative that peacekeeping is failing has contributed to decreasing budgets and stalemates in the UN Security Council. The council has not authorised a new, major peacekeeping mission in eight years.
Although UN peacekeeping has many challenges, it remains an important instrument of peace.
Peacekeeping in Africa
During the 2000s, South Asian countries – Bangladesh, India, Nepal and Pakistan – supplied the most peacekeeping troops. By the 2010s, however, both top troop contributions and the locations of the most complex missions had shifted to Africa.
Most UN troops now come from the continent and it is home to six of the 12 current missions, including the largest four. These missions are in the Democratic Republic of Congo, the Central African Republic, Mali and South Sudan.
This shift in numbers reflects two trends.
First, it embodies the institutionalisation of the idea of “African solutions to African problems”. This idea was coined by the late Ghanaian economist George Ayittey in the wake of the United States’ disastrous operation in Somalia, and has been widely debated ever since. It represents a response to the legacies of slavery, colonialism and, more recently, exploitative and abusive practices.
Second, it reflects a shift in some basic principles. Research on the transition from the Organisation of African Unity to the African Union traces a move from the principle of “non-interference” to “non-indifference”. Regional and other organisations were expected to help prevent conflict within states and save lives.
Similar shifts occurred in the UN system more broadly. These were reflected in the 2005 adoption of the Responsibility to Protect doctrine.
The overall mission and troop numbers have diminished since then – to 12 missions and about 90,000 personnel – for a variety of reasons. Most notable is the absence of financial support during US president Donald Trump’s administration between 2017 and 2021.
About half of the current UN peacekeeping operations are simple cease-fire monitoring missions, and the others are more complex state-building efforts in civil wars.
The three most complex missions – in Mali, the Democratic Republic of Congo and the Central African Republic – are termed “stabilisation” missions. These missions face a wide array of challenges, including undemocratic political transitions, illicit networks and terrorists. But all else being equal, they are saving lives and preventing the spread of violence.
The trouble with peacekeeping
There are also other problems. Mercenaries have been deployed in Central Africa and Mali, and even well-intentioned external forces can bring negative, unintended consequences.
But that is not the end of the story.
The good news
More than a dozen quantitative studies published in top peer-reviewed journals have shown – using different datasets, metrics, time periods and controls – that peacekeepers are protecting civilians. It is one of the most robust findings in the field of international relations, and most of these studies narrow the case selection to peacekeeping in Africa.
There is a connection between diversity in peacekeeping and fewer civilian deaths. Whereas military fighting requires unity of command and training, peacekeeping doesn’t work the same way. In peacekeeping, diversity of skills and experience are connected to better outcomes.
It has also prevented violence from recurring, reduced the duration of wars and helped foster the growth of robust civil societies. Peacekeeping is additionally associated with less sexual and gender-based violence during violent conflict.
Since the end of the Cold War, the UN has completed complex peacekeeping missions in 16 conflicts. Of these, 11 successfully implemented mandates and departed the countries. None of those countries has returned to civil war. That is a two-thirds success rate.
The most notable failed missions are the ones people remember vividly – in Somalia, Rwanda, Bosnia and more recently Haiti. As tragically as those missions ended, they are not the norm.
More frequently – such as in Namibia, Sierra Leone, Côte d’Ivoire, Liberia, El Salvador, Cambodia, Eastern Slavonia/Croatia and Timor Leste – the UN’s state-building missions have succeeded at fulfilling complex mandates and departing.
Years later, these countries are not all perfect democracies, but neither are they at war.
The future of peacekeeping
Peacekeeping is not war fighting.
The doctrine of peacekeeping has three parts: consent of the parties, impartiality and the limited use of force.
It is fundamentally unlike counterinsurgency or counter-terrorism missions, which deploy without consent, take the side of the government and often employ offensive force to achieve military gains.
Although UN peacekeeping has been effective, it is not figuring in diplomatic efforts to end conflicts or assist in major transitions, such as those in Ethiopia, Sudan or Libya.
Third-party peacekeepers are not at the table, despite that fact that academic research over the decades has demonstrated that the promise of peacekeeping helps parties agree to peace.
