The UN’s Cruz Report on Improving Peacekeepers’ Security Goes Too Far

Since 1999, the United Nations Security Council has consistently entrusted its peacekeeping operations with clear authority to use force beyond self-defense — primarily for the protection of civilians. To fulfill the mandate, the Council expects UN peacekeeping forces to take preventive as well as responsive actions; to proactively patrol the local communities; to project a strong deterrent posture; and to be robust in defending themselves and protecting civilians.

For too long, however, there has been a clear gap between expectation and performance. Despite the failures, the Council now expects UN forces to conduct strategic and ever more aggressive operations to help stabilize increasingly hostile environments and to neutralize insurgents in the Democratic Republic of the Congo, terrorists in Mali and government forces in South Sudan.

The rising death toll among UN peacekeepers is one of many consequences of UN engagement with such actors in such environments.

In the UN’s recently published Cruz report, “Improving the Security of UN Peacekeepers,” Lt. Gen. Carlos Alberto dos Santos Cruz and his fellow authors note that 195 personnel have been killed by violence since 2013, “more than during any other 5-year period in history” — and that 56 of them were killed in 2017 alone — “the highest number since 1994.”

The authors proceed to set out concrete and comprehensive recommendations on how the UN can improve the security of UN peacekeepers. By calling on UN peacekeepers to use “overwhelming force,” as opposed to robust defensive or protective force, the Cruz report may have gone too far, potentially undermining the security of both UN personnel and the civilians they are meant to protect. (A UN Security Council session on protecting civilians in armed conflict is scheduled for May 22.)

While UN peace operations must be proactive in preventing and decisive in responding to attacks on civilians and against UN personnel, property and premises, UN peacekeepers should not be called on to use overwhelming or aggressive force.

Here is why:

First, the UN calls on the troops of one country to fight and possibly die for the cause of peace in another country. The willingness to make the ultimate sacrifice under such circumstances is already difficult to achieve when there is no peace to keep. Calling on the troops to actively participate in warlike behavior will destroy their impartiality, hinder their peace efforts and more likely increase rather than decrease their vulnerability. Without prejudice to its inherent right of self-defense and its protection of civilian mandate, a UN peacekeeping operation should be more concerned about being an impartial agent of peace rather than as a successful force of war. It may therefore be far better for the security of UN personnel and civilians alike for peacekeepers to be more useful as peacemakers rather than as peace enforcers — to be more proactive in proposing peace plans and more aggressive in bringing parties to peace talks.

Second, as a legal matter, using “overwhelming force” may constitute excessive force, contravening the standard UN rules of engagement on the use of targeted, proportionate, graduated and minimum force necessary to achieve the authorized military objective.

Third, calling on UN peacekeeping operations to use overwhelming force also increases the likelihood of their becoming parties to the conflicts under international humanitarian law. The Cruz report does not take into account that, at least once, a current peacekeeping mission has become a party to the conflict. As a result of aggressive operations that its forces have conducted against the M23 militia, the UN mission in the Congo, called Monusco, has become a party to the conflict in the country. As such, its forces have lost their protected status and have become legitimate military targets under international humanitarian law.

By ignoring the legal consequences of using aggressive force, the Cruz report has mirrored the Security Council’s own disregard for the applicability of international humanitarian law to Monusco. The report insists on referring to all attacks on UN peacekeeping operations as “war crimes” while the Council continues to impose Chapter VII sanctions on those planning, directing or conducting such attacks.

Without prejudice to the Council’s prerogatives in this regard, and to the extent that its resolutions call on all parties to respect international humanitarian law, a clear understanding of IHL’s implications is necessary to ensure that UN forces are aware of the loss of their protected status under the law and that, as such, they become exposed to direct attack and thus pose a greater threat to the very civilians they are meant to protect.

Lastly, while the Cruz report calls for accountability for crimes against UN peacekeepers, it fails to call equally for accountability for crimes committed by UN peacekeepers. The lack of criminal accountability for the latter crimes — including sexual crimes — has demonstrably diminished the credibility and legitimacy of UN peacekeeping operations in the hearts and minds of the local populations they are supposed to protect, further increasing peacekeepers’ vulnerability to attack.

It does not have to be all or nothing. My article maintains that UNPKO forces can and should fully and robustly use force in self-defense and for the protection of civilians – against hostile actors and hostile acts especially in the face of such atrocities as have been committed in places like DRC, South Sudan, Mali and CAR. Using the necessary and proportionate force to achieve these legitimate military objectives does not, however have to be overwhelming, aggressive or offensive in order to be credible and effective.

dont quite agree with the findings and the comments. i was srsg at monusco with general cruz as force commander at monusco in the congo. we were responsible for the m23 operations. i am convinced: the UN is impartial when it comes to politics, but we are not neutral when it comes to human rights violations. the UN has to become a party. the UN is party to protect human rights, to protect women who are subject to mass rape, we are party to protect children who are drugged by armed groups and forced to commit cruelties you dont even dream of. UN peacekeepers cannot stand idle – as i have seen – 9 km from a place of massacre and just let it happen. i witnessed that we lost so much credibility by NOT intervening. being partial when it comes to the values of human rights is what the UN stands for!

It’s clear that the UN will not take up the Cruz report recommendations. They have had ample time to do so, or to moderate any action suggested. It is also clear that UN forces will remain ineffective against the type of conflict perpetrated in Eastern DRC, and elsewhere. As noted, there is no peace for peacekeepers to keep. In the DRC, when President Kabila decides to end the violence and commit his military forces against the rebels, there may be peace to keep. But, in many cases, the relationships between the government and its rebels is not always clear. Crimes and abuses by UN forces must be dealt with swiftly and effectively. The accused must be sent back to their country of origin immediately to take away the monies they hoped to gain. If they are cleared, they may return. In some cases, research has suggested, however, that such abuses are tolerated as a way create unit cohesiveness, especially when forces remain unpaid. This is potentially true for national forces like the FARDC – where the research was completed. While the analysis has excellent points, it does not provide any concrete suggestion how the UN might be effective in its deployed missions. To do what they have been doing is the classic definition of insanity.

A very cogent analysis. The UNO is already dealing with the crises in missions, agencies, funds and programs, brought about by its response to, and handling of, sexual exploitation and abuse by peacekeepers and other staff members. It doesn’t need to add any more self-inflicted wounds to its credibility and legitimacy.

Bravo to the author.
The Security Council’s mandates on such aggressive use of force go far beyond Charter letter and spirt. The consequences, felt harshly by all concerned, will hit the UN’s overall legitimacy the hardest, probably irreversibly. Council experiments these past years have created a Jurassic Park of freakish and failed operations costing lives and compromising UN credibility and purpose.
