The global commentary machine erupted in predictable outrage when Iran’s Supreme Leader declared that American presidential signatures are "worthless," pointing to the collapse of the Joint Comprehensive Plan of Action (JCPOA) under the Trump administration. Pundits wrung their hands, weeping over the tragic demise of international trust and the sudden fragility of American diplomacy.
They are missing the entire point.
The lazy consensus insists that a change in White House occupancy shattered a perfectly stable, binding agreement. This narrative is comforting because it blames a single, volatile individual for a systemic reality. The uncomfortable truth? A U.S. presidential signature on a non-treaty executive agreement has always been fundamentally worthless for long-term strategic planning. It is not a flaw in the system; it is the system operating exactly as designed. Treating a political handshake as an immutable law is a failure of basic geopolitical literacy.
The Executive Agreement Delusion
International relations novices confuse executive agreements with ratified treaties. Having spent decades analyzing structural foreign policy shifts, I have watched foreign ministries and corporate boards repeatedly burn billions of dollars by betting on the permanence of executive pen strokes.
Under the U.S. Constitution, a formal treaty requires the advice and consent of two-thirds of the Senate. This high bar ensures broad, bipartisan buy-in that survives shifting political tides. The JCPOA was explicitly structured as a non-binding political commitment precisely because its architects knew it could never clear the Senate hurdle.
When an American president signs a political commitment, they are not signing on behalf of the United States as a permanent state apparatus. They are signing on behalf of their specific administration. Expecting a subsequent administration from an opposing party to honor that deal is like expecting a new corporate CEO to honor a casual verbal agreement made by their predecessor before they were fired.
The Myth of "International Trust"
Diplomats love to talk about "credibility" and "trust" as if they are tangible commodities traded on a global exchange. They are not. Nations do not act out of loyalty or honor; they act out of calculated self-interest, constrained by domestic pressures.
Consider the baseline mechanics of state behavior. The concept of anarchy in international relations, articulated by political scientists like John Mearsheimer, dictates that there is no global police force to enforce contracts between sovereign states. Security and survival dictate policy, not sentimentality.
When the U.S. walked away from the Iran deal, it was not an unprecedented betrayal that permanently broke global diplomacy. It was the predictable result of a structural flaw in the deal itself: it lacked domestic legislative institutionalization.
Imagine a scenario where a company signs a massive vendor contract, but the bylaws state the contract can be vetoed by any internal manager at any time without penalty. No serious CFO would invest capital based on that contract. Yet, the entire geopolitical commentariat expected Iran, Europe, and global markets to treat the JCPOA as holy writ. The mistake was not the exit; the mistake was the naive belief that the entrance was permanent.
The Flawed Premise of "People Also Ask"
Look at the questions dominating public discourse surrounding this friction:
- Can the US be trusted to keep international agreements?
- How do changes in US presidency affect foreign policy stability?
- Why did the US pull out of the Iran nuclear deal?
Every single one of these questions is fundamentally flawed because they presume stability is the default state of international pacts.
The brutal answer to whether the U.S. can be trusted is: Yes, but only when an agreement is backed by structural incentives or formal ratification. The U.S. rarely abandons ratified treaties because the domestic political and legal costs of doing so are prohibitively high. The U.S. routinely shifts stances on political commitments because the domestic political cost of maintaining them often outweighs the benefits when power changes hands.
Foreign policy stability is an anomaly, not the rule. The presidency is a structural pendulum. If a foreign adversary or an international ally builds a long-term strategy on the assumption that the pendulum will remain static, they are committing strategic malpractice.
The Downside of Structural Realism
Admitting that signatures are temporary political instruments comes with a brutal downside. It means negotiating lasting deals with adversaries becomes nearly impossible in a polarized domestic environment. If you cannot offer permanence, you cannot demand long-term concessions.
This reality forces diplomacy to become purely transactional, short-term, and cynical. It replaces grand visions of regional transformation with mercenary, tit-for-tat arrangements. But acknowledging this bleak reality is infinitely safer than pretending a signed piece of paper offers a shield against structural political shifts.
Stop Reading the Ink, Look at the Incentives
Stop analyzing the rhetoric of supreme leaders or the tweets of former presidents. The ink on the paper means nothing.
If you want to know if an international agreement will survive the next election cycle, ignore the signing ceremony. Look at the domestic legislative support. Look at the economic alignment of the industries inside the signing nations. Look at whether the deal creates a coalition of domestic stakeholders who will lose money if the deal dies.
If a deal relies entirely on the political survival of the person who signed it, the agreement is already dead. It just hasn't been buried yet. Stop mourning the breakdown of worthless signatures and start measuring the hard calculus of national self-interest. That is the only contract that ever gets honored.
