I write this with a heavy heart, but also with deep gratitude for a life that gave so much to the cause of peace, justice, and human dignity.

Nicholas “Fink” Haysom, who passed away last month, was not just another senior United Nations diplomat. He belonged to a fading breed: those who approached diplomacy and peacemaking not simply as a profession, but as a vocation. For him, diplomacy was never about position or protocol. It was about purpose, conviction, and an enduring commitment to humanity.

He was shaped in the crucible of the anti-apartheid struggle — a defining historical experience that produced a generation of leaders who understood injustice intimately and resisted it with both moral clarity and political discipline. From that struggle, Fink carried forward a rare combination: a principled legal mind grounded in public service, and a political sensibility anchored in justice.

Listening as a moral act 

I first encountered Fink during the negotiations that led to the Sudan Comprehensive Peace Agreement. From the outset, I found myself under his wing. His style was neither loud nor imposing. He did not dominate the room; he steadied it. He did not rush toward solutions; he cultivated them patiently, with care, discipline, and respect for complexity.

What distinguished him most was his discipline of listening.

Fink listened not as a formality, but as a moral act. He understood that conflicts are not merely technical problems to be solved, but historical and human realities to be understood. He gave conflict, and those shaped by it, the seriousness they deserved. He was meticulous in defining the problem before attempting to resolve it — an increasingly rare quality in today’s fast-paced and often superficial diplomatic engagements.

I later had the privilege of working closely with him again when he succeeded Haile Menkerios as the United Nations envoy during the final and most delicate phase of negotiations between Sudan and South Sudan. This was a moment without precedent in Africa: a negotiated separation of two states. The stakes were immense, the tensions acute, and the risks of failure catastrophic.

In that moment, Fink’s experience and judgment proved invaluable.

A people’s negotiator grounded in the political realities of conflicts

He played a vital role not only in the negotiations themselves, but also in managing the relationship between the African Union and the United Nations Security Council. Under his stewardship, cooperation between the AU Peace and Security Council and the UN Security Council reached a level of alignment and effectiveness that remains a benchmark in multilateral peacemaking.

He enjoyed the trust of President Thabo Mbeki, who chaired the AU High-Level Implementation Panel. Their relationship, forged in shared struggle, brought both political depth and personal trust to a process that required both in equal measure.

Fink was, in every sense, a diplomat’s diplomat.

But more than that, he was what I would call a people’s negotiator.

He was accessible, persuasive, and deeply grounded in the political realities of the conflicts he engaged. He was never confined by the narrow boundaries of job descriptions. He worked tirelessly. He made time to listen. He was consistently, and quietly, the adult in the room.

Mediation and diplomacy are now losing their moral and political centers 

Yet, his passing comes at a sobering historical moment.

We are living through a period in which diplomacy — globally — has been diminished, hollowed out, and in far too many cases displaced by transactional deal-making. Multilateralism is under strain. Norm-based mediation has declined. Short-term bargains and interest-driven alignments are increasingly replacing serious, principled diplomatic engagement.

This shift is not merely institutional. Its consequences are profound and dangerous.

When diplomacy loses its moral and political center, war gains ground. When mediators are reduced to brokers of temporary arrangements rather than stewards of political solutions, peace processes lose legitimacy. Ceasefires are detached from political vision. Negotiations proceed without trust. And outcomes, even when reached, prove fragile and unsustainable.

It is precisely in contrast to this troubling trajectory that Fink’s life and work stand out so clearly.

He represented a generation of diplomats for whom diplomacy was anchored in seriousness, intellectual discipline, discretion, and a deep sense of responsibility to those whose lives were shaped by conflict. He did not practice mediation as a transactional exercise. He practiced it as a principled endeavor — one that required patience, legitimacy, and a constant awareness of the human consequences of failure.

Fink was not an elitist negotiator. He did not practice diplomacy from a distance. His approach was profoundly people-centered. He remained constantly aware that behind every negotiation were lives at stake: communities shattered, futures imperiled, and human dignity under assault.

He ensured that all parties remained mindful of these realities — not through grandstanding, but through quiet and persistent insistence on responsibility.

In mourning Fink, we are not only grieving the loss of an extraordinary individual.

We are also marking the passing of a generation.

A generation of diplomats shaped by struggle, anchored in principle, and committed to multilateralism not as a convenience, but as a necessity. A generation that understood diplomacy as a serious craft — one that required both moral clarity and political judgment.

Principled diplomats are needed in a world of upheaval and crisis 

That generation is fading at a time when it is needed most.

The erosion of such principled diplomats is increasingly at the heart of the failure of contemporary mediation to avert, manage, and resolve conflicts. Where their presence once ensured depth, legitimacy, and coherence, their absence is often filled by fragmented initiatives, externally driven agendas, and short-term arrangements that lack both vision and sustainability.

This is not inevitable. But it is deeply concerning.

Fink’s life reminds us that diplomacy, at its best, is not about managing crises — it is about resolving them. It is not about process alone — it is about purpose. And it is not about proximity to power — it is about fidelity to principle.

Beyond the negotiating table, I recall with great fondness the many conversations we shared — political, reflective, and often filled with humor. There was laughter, even in the most demanding circumstances. There was ease, but never at the expense of seriousness.

Those of us who worked with him did not only grow professionally; we became better human beings.

Fink had a particular way of addressing those he held in regard: he would call you “comrade.”

In his usage, this was never casual. It signified a shared commitment—to justice, to fairness, and to the collective struggle for a better world. It reflected a relationship grounded not merely in familiarity, but in shared purpose. In this, he embodied what we, as Africans, understand as Ubuntu—the idea that our humanity is bound up with one another.

His life traced a seamless arc — from the struggle against apartheid, to service in democratic South Africa, to global peacemaking through the United Nations. There was no rupture, no loss of moral center. The values that defined him in struggle remained intact in service.

This continuity is what made him rare.

A moment of reflection that underlies a need to revive principled diplomacy 

In a world where proximity to power often alters individuals, Fink remained anchored. He reminds us that leadership is not about office, but about the consistency of values across time and circumstance.

His passing invites not only reflection, but introspection.

Are we cultivating a new generation of diplomats capable not only of technical competence, but of moral seriousness?

Are our institutions producing mediators who can match the complexity of today’s conflicts with depth, patience, and principle?

These are not rhetorical questions. They are strategic imperatives.

Fink did not simply practice diplomacy. He dignified it.

His legacy will endure — in the peace processes he helped advance, in the institutions he strengthened, and in the lives he touched. But more importantly, it endures as a standard.

A standard of what diplomacy can be at its best.

Farewell, Comrade.

May Allah grant him eternal peace, and may we find the courage to carry forward the work to which he devoted his life.
