The question of who conceded more in a peace agreement is less interesting than the question that precedes it: what kind of agreement produces durable peace? The history of twentieth and twenty-first century conflicts offers an uncomfortable answer for the architects of the US–Iran MoU. The agreements that lasted were not, in general, those that distributed concessions most equitably. They were those that structurally transformed one or both parties — their institutions, their military capacity, their place in the international system. The agreements that did not last were, with a disturbing consistency, those that froze the conflict without resolving its causes.
Two models emerge with sufficient clarity to be useful. The first is structural capitulation as the foundation of peace: one side surrenders not merely territory or instruments of pressure, but the architecture that made conflict possible and recurrent. The second is the ceasefire as a factory of recurrence: the parties stop fighting without resolving what led them to fight, and the interval serves to reconstitute capacity and await more favourable conditions.
Model I — Structural Capitulation as the Foundation of Peace
Germany, 1945
Unconditional surrender in May 1945. Physical occupation of the territory. Denazification. A new constitution imposed from outside. The Marshall Plan. Integration into NATO and the emerging European structures. Seventy years of peace at the heart of the continent that had been the epicentre of two world conflicts in three decades.
The German peace lasted not because the concessions were balanced — they were not, from any angle — but because the defeat was sufficiently total to permit the refoundation of the state and of collective identity. The Allies did not lift the pressure after the surrender; they increased it, deliberately and sustainedly, until systemic transformation was achieved. The reversibility of Germany's concessions was zero: there is no way to unconstitute a constitution that has become the basis of the political legitimacy of a democratic state.
Japan, 1945
General MacArthur imposed a constitution, complete disarmament, land reform and commercial opening. Article 9 of the Japanese constitution renounced war as an instrument of state policy. The surrender was total and the subsequent institutional framework was designed by the victor without negotiation.
Eighty years of relative regional peace — with all their tensions and ambiguities — resulted not from a balance of concessions but from a reconfiguration that Japan internalised and made its own across generations. The initial political cost for Tokyo was immense. The durability was proportional to the depth of the transformation.
Finland, 1944
The Moscow Peace imposed on Finland substantial territorial concessions — Karelia —, war reparations paid over years, and limitations on its foreign policy (the so-called "Finlandisation"). Finland's concessions were disproportionately larger than the Soviet Union's. The peace lasted because Helsinki complied fully and Moscow calculated that the cost of continuing outweighed the marginal gain of a new offensive.
The Finnish case is instructive for a different reason: it demonstrates that asymmetry of concessions does not preclude durability, provided the weaker side complies credibly and the stronger side has no incentive to restart the conflict. It is a model of peace through calculated subordination, not through mutual transformation.
Model II — Ceasefire as a Factory of Recurrence
Korea, 1953
The armistice of July 1953 stopped the fighting along the 38th parallel. There was no peace treaty. The peninsula remains technically at war. North Korea developed nuclear capability precisely because the 1953 framework did not address the structural causes — only the line of fire. The armistice managed the conflict; it did not resolve it.
Lebanon, 2006
The ceasefire between Israel and Hezbollah after 34 days of war in 2006 was enshrined in UN Security Council Resolution 1701, which demanded Hezbollah's disarmament south of the Litani River. Twenty years later, Hezbollah had reached an unprecedented arsenal capacity before the 2024 conflict. Resolution 1701 survived as text; it died as a mechanism in the very moment it was adopted.
Iran–Iraq, 1988
The ceasefire that ended eight years of war between Iran and Iraq was not accompanied by a treaty, territorial resolution, or robust verification mechanism. The structural causes — the Shatt al-Arab border, regional ambitions, sectarian identity — remained intact. Saddam Hussein invaded Kuwait two years later. The ceasefire created the interval; it did not create the conditions for that interval to become peace.
Ukraine, Minsk I and II, 2014–2015
The Minsk Agreements were signed in September 2014 and February 2015 following Russia's annexation of Crimea and the start of the Donbas conflict. Neither party complied fully. Russia used the period of formal validity to reposition forces and consolidate control over occupied territories. The large-scale invasion of February 2022 was, among other things, the final collapse of a framework that had never addressed the fundamental question: Ukrainian sovereignty and its choice of geopolitical alignment.
A ceasefire manages the conflict. It does not resolve it. The difference between the two is not semantic — it is the difference between seventy years of peace and seventy years of armistice.
The pattern that emerges from historical comparison
The Pattern and Its Variables
Durable peace correlates, in the historical evidence, with three variables that ceasefires rarely produce. The first is institutional transformation — of the defeated party, of both parties, or of the systemic framework in which the conflict occurred. The second is verification with real coercive power — not the promise of inspection, but the mechanism that makes violation costly before it occurs. The third is resolution of structural causes — not their management, not their postponement, but their direct address, even if partial and imperfect.
The cases in Model I share at least two of these three variables. The cases in Model II share the absence of at least two of the three. Korea 1953 had no institutional transformation of the North, no robust verification and no resolution of structural causes. Lebanon 2006 had no verification with teeth and no resolution of Hezbollah as an armed non-state actor. Minsk did not resolve the question of Ukrainian sovereignty. Iran–Iraq 1988 resolved none of the three.
The US–Iran MoU: Which Model?
Applied to the US–Iran MoU, this analytical framework produces an uncomfortable diagnosis. The agreement has a ceasefire — Points 1 to 5, the confirmed hard core. It has wider framework language — Point 14, with a Medium/Low confidence rating. It has a 60-day follow-on clause — Point 13, the structural hinge on which everything else depends.
What it does not have is institutional transformation. The Iranian nuclear programme is not being dismantled — it is being paused, with moratoriums whose verification terms have not been confirmed. The proxy architecture — Hezbollah, the Houthis, Shia militia in Iraq and Syria — is not being substantively addressed. And the structural causes of the regional conflict — the question of Iran's legitimacy in the Middle East security system, the relationship between Tehran and Tel Aviv, the role of the Gulf monarchies in a new regional balance — are left to future negotiations whose calendar and scope are, at this moment, aspirational.
This is not a criticism of the agreement. It is a reading of its nature. A ceasefire that opens space for substantive negotiation is valuable — more valuable than the alternative of continued conflict. But the space it opens only converts into peace if it is filled with the elements that history demonstrates are necessary. The interval between the Geneva signing and the 60-day follow-on talks is exactly that: an interval. What happens in that interval will determine whether the MoU is the beginning of something or merely the latest in a series.
History is not deterministic. Germany and Japan in 1945 were cases that no one, in 1944, would have wagered would produce seventy years of peace. But the peace they produced was not an accident — it was the result of deliberate choices about the depth of transformation that was required.
The US–Iran MoU has not yet made those choices. It may make them in the 60 days that follow. Or it may join the long list of agreements that history remembers for what they promised rather than for what they delivered.
Geneva is a date.
Peace is an architecture.
