Why the Era of Institutional Peacemaking Has Come to an End

The metrics are stark: state-to-state conflicts reached a post-1945 record of 65 last year, and global military spending has expanded by 41 percent over the past decade. The United Nations Security Council — nominally the guarantor of international peace — has failed to contain crises in Ukraine, Myanmar, Gaza, and Sudan.

What the institutional model cannot fix

The post-1990s "peace industry" — the U.N., regional bodies, NGOs deploying frameworks for sustainable peacebuilding — depended on geopolitical conditions that no longer exist. The boom that ended civil wars from Liberia to Timor-Leste was less a permanent achievement than an anomalous byproduct of temporarily reduced great-power tension. When the underlying equilibrium shifts, the institutions built on top of it lose their leverage.

The last comprehensive peace deal — Colombia, signed roughly a decade ago — marks the dividing line. Since then, institutional peacemaking has lost momentum.

Where the levers might actually be

The historical record offers a guide. During the Cold War, superpowers fueled proxy wars across continents yet still found off-ramps and signed arms-control agreements. Peace efforts in that era were not driven by ideologically committed institutions but by the practical calculations of states with something to lose.

For today's observers, the implication is uncomfortable: useful peacemaking will not come from the institutions that defined the previous era. It will come from actors — great powers and regional players — operating on cold strategic logic.

That demands a different literacy. Former Singapore diplomat Bilahari Kausikan, in a recent address, identified two recurring failure modes in public discussion of foreign policy: confusing opinions with facts, and fixating on events without reading the structural conditions that produce them. Both mistakes make coherent responses harder.

The same erosion hollowing out international peace structures plays out at every scale. The mechanisms we rely on to safeguard stability — from the Security Council down to the systems guarding personal data — are exhibiting identical fragility. A parallel pattern of institutional leakage appears in more mundane contexts, where trusted financial structures quietly lose their grip on the information they were designed to protect.

What to watch

Three signals will indicate whether the shift toward power-politics peacemaking stabilizes or deepens:

1. Whether any major-power brokered agreement emerges from active conflict zones — Ukraine, Gaza, Sudan — resembling a Cold War-era off-ramp.

2. Whether military spending growth continues its decade-long trajectory, or begins to plateau under economic constraints.

3. Whether regional organizations develop genuine mediation capacity independent of the Security Council's paralysis.

Waiting for institutional revival is not a workable strategy. The structural conditions that produced the post-Cold War peace boom have already shifted. The actors willing to operate within new conditions — not the institutions clinging to the old framework — will shape what comes next.
