A Document, Not a Settlement
On Wednesday, President Trump and Iranian President Masoud Pezeshkian signed a memorandum of understanding intended to end active hostilities between the United States and Iran. Pakistan’s prime minister co-signed the document. The text is now public. Reading it against the architecture of prior agreements — the 2015 JCPOA, the Algiers Accords, the Abraham Accords — reveals what this document is and, more precisely, what it is not.
A memorandum of understanding carries no binding force under international law. It is a statement of intent, not a treaty. It does not require Senate ratification. It does not create enforceable obligations on either signatory. It is the formal record of a conversation, not the resolution of a conflict.
What the Text Commits
The memorandum, as published, commits both parties to cessation of direct military hostilities, establishment of a diplomatic channel for further negotiation, and a general framework for economic normalization discussions. These are not trivial commitments. The cessation of active hostilities — if it holds — ends a conflict that has cost both governments substantial military and economic capital.
The language on economic normalization is deliberate in its vagueness. It references the possibility of sanctions relief tied to future compliance benchmarks. It does not specify which sanctions, which benchmarks, or which body adjudicates compliance. The sanctions architecture the United States has constructed against Iran across four administrations — OFAC designations, secondary sanctions on third-country financial institutions, oil export restrictions — remains fully intact. The memorandum creates no mechanism to dismantle any of it.
What It Does Not Address
The three questions that have defined U.S.-Iran relations for two decades are absent from the operative text in any actionable form.
Iran’s nuclear enrichment program receives a reference, not a framework. The document acknowledges that enrichment is a subject for future negotiation. It does not cap enrichment levels, require IAEA access beyond existing agreements, or establish a timeline for any of these discussions. Iran currently enriches uranium to levels that, by IAEA estimates, place it weeks from weapons-grade material. The memorandum does not alter that timeline.
The sanctions regime — the primary instrument of U.S. pressure for twenty years — is mentioned as a subject for future discussion contingent on future compliance with terms not yet negotiated. This is the diplomatic equivalent of a promissory note with no specified amount, no due date, and no collateral.
Iran’s network of regional proxy forces — Hezbollah, the Houthis, Iraqi Shia militias — is not addressed in the text at all. These forces have been the primary mechanism through which Iran has projected power across the Middle East. An agreement that ends direct U.S.-Iran hostilities while leaving proxy infrastructure intact does not fundamentally alter the regional power equation.
Pakistan at the Table
The inclusion of Pakistan’s prime minister as a co-signatory is the document’s most structurally unusual feature. Pakistan is not a party to the U.S.-Iran conflict. It does not share a land border with Iran in a way that makes it a natural mediator. Its inclusion suggests a deliberate effort to frame the agreement as a regional stabilization initiative rather than a bilateral deal — which would have implications for how it is read in Riyadh, Abu Dhabi, and Tel Aviv, all of whom have compelling reasons to view any U.S.-Iran rapprochement with alarm.
Israel, which conducted its own strikes on Iranian nuclear infrastructure in the preceding months, is not party to the agreement and has not publicly endorsed it. The memorandum does not address the Israeli-Iranian dimension of the conflict, which operates on a separate military and diplomatic track.
Pakistan's prime minister co-signed the memorandum, a structural inclusion that reframes the agreement as a regional arrangement rather than a bilateral U.S.-Iran framework.

Every prior agreement with Iran has failed not because it was poorly written but because it was structurally incomplete. The JCPOA capped enrichment and provided verification but left regional proxy activity, ballistic missile development, and sunset clauses as unresolved vulnerabilities. When the United States withdrew in 2018, the agreement collapsed in months.
This memorandum is less comprehensive than the JCPOA. It addresses fewer issues, with less specificity, and carries no binding legal mechanism. The optimistic reading is that it creates a ceasefire from which a more durable agreement can be built. The structural reading is that it recreates the same dynamic that has defined every prior diplomatic episode with Tehran: an initial framework celebrated as a breakthrough, followed by years of contested implementation, followed by collapse at the point where core interests cannot be reconciled.
The Architecture of Incompleteness
Diplomacy that ends active hostilities is not nothing. Wars consume resources, generate domestic political pressure, and produce outcomes that are rarely controlled by either party. A memorandum that stops the shooting buys time. The question this document raises is what that time will be used for.
The enrichment clock does not pause during negotiations. The sanctions architecture does not soften during goodwill gestures. The proxy networks do not stand down while diplomats draft frameworks. A memorandum of understanding, signed without verification mechanisms, without Senate ratification, and without resolution of the three structural questions that produced the conflict, is a ceasefire agreement dressed in diplomatic language. Whether it becomes something more durable depends entirely on what neither document nor ceremony can guarantee: sustained political will on both sides to confront the questions the text deliberately avoids.
