The cancellation of Friday’s Iran-US talks in Switzerland, coming just days after the memorandum of understanding was signed by Masoud Pezeshkian and Donald Trump, may at first glance appear to signal the fragility of the deal, or even the beginning of its collapse. The timing, alongside new Israeli attacks on Lebanon and rising regional tensions, has reinforced that perception. The reality, however, is likely more complex than the headlines suggest.
In diplomacy, particularly when dealing with decades-long disputes and issues as complex as Iran-US relations, not every delay or suspension should be interpreted as failure. The history of major international negotiations shows that the most difficult phase is often not the start of talks, but the period after an initial agreement is reached, when broad commitments must be translated into implementation mechanisms, timelines, and verifiable guarantees.
The signing of the Tehran-Washington memorandum was not the end of a process but the beginning of a new and far more sensitive phase. Fundamental questions now arise, from the timing and sequencing of sanctions relief to verification mechanisms, regional security arrangements, and the scope of mutual commitments. Under such circumstances, any difference in interpretation or any development on the ground can disrupt the negotiating process.
Beyond these technical complexities, the role of third parties cannot be ignored. The latest Israeli attacks on Lebanon occurred precisely when implementation talks were set to begin in Switzerland. Regardless of whether the timing was deliberate, one fact is clear: parts of Israel’s political and security establishment are concerned about any reduction in tensions between Iran and the US. Over the past two decades, much of Tel Aviv’s regional standing has been built around portraying Iran as the primary threat to Middle East security. Any agreement that reduces that confrontation would naturally alter regional power dynamics.
At the same time, Tehran cannot view developments in Lebanon as entirely separate. The Islamic Republic has consistently maintained that the security of its regional allies is part of its national security equation. Entering sensitive negotiations while one of its key allies faces military pressure could, from the perspective of Iranian decision-makers, send conflicting signals.
Washington also faces a difficult balancing act. The Trump administration has presented the agreement with Iran as a major foreign policy achievement and wants to see it succeed. At the same time, it is reluctant to bear the political cost of an open confrontation with Israel. The White House is therefore compelled to balance two sometimes competing objectives: advancing the agreement with Iran while preserving cohesion within its traditional regional alliance structure.
Another factor is domestic opposition to the agreement in both countries. In Iran, memories of the US withdrawal from the JCPOA remain vivid, and many continue to question the durability of any new deal. In the US, powerful political and security circles view any compromise with Tehran as a concession to a rival. Under such conditions, every new step toward an agreement is likely to face political and media resistance.
From this perspective, the greatest analytical mistake may be to treat the cancellation of the Switzerland talks as the endpoint of a process. What we are seeing today resembles the first serious post-agreement crisis rather than a weakening of the agreement’s foundations. The true value of any agreement is measured not on the day it is signed, but by the parties’ ability to navigate the inevitable crises that follow.
The three principal actors are now testing one another’s resolve and capabilities. Israel seeks to demonstrate that no new regional order can emerge without accounting for its security concerns. Iran is attempting to show that an agreement with the US does not mean abandoning its regional and security considerations. And the US is trying to establish a sustainable balance between these competing realities.
For that reason, what happened in Switzerland should be viewed less as a diplomatic failure and more as part of a broader struggle over the future shape of the regional order. The fate of the agreement will not be determined by the cancellation of a single meeting, but by how these crises are managed. If the parties can navigate this challenge, the agreement may enter a phase of consolidation. If battlefield tensions and pressure from opponents overwhelm diplomacy, however, this temporary pause could mark the beginning of a gradual erosion of an agreement still in its earliest stages.
