Iran-US Diplomacy: Beyond the 'Who Moves First' Stalemate

For almost two decades, a persistent question has loomed over Iran-US diplomacy: who should make the initial move? Since the early 2000s, Washington and Tehran have grappled with the same dilemma: should Iran curtail its nuclear activities in exchange for economic relief, or should the United States ease pressure before expecting Iranian concessions? However, the current diplomatic crisis suggests these questions may be outdated. The true challenge lies not in who moves first, but whether both sides can move in tandem. This issue has regained urgency amidst the latest dispute concerning the Strait of Hormuz. Tehran has proposed reopening the waterway, contingent upon Washington fulfilling a series of conditions, including the lifting of the naval blockade, easing sanctions, and providing assurances against further attacks. Iran contends that negotiations cannot commence under duress and confrontation. Conversely, Washington maintains that any renewed diplomatic process must address the nuclear issue from the outset. This divergence highlights the central problem in current negotiations: both parties demand confidence-building measures before taking any initial step. Historical precedent indicates that this deadlock has been resolved previously through mechanisms predicated on reciprocal actions. The 2013 Joint Plan of Action between Iran and the P5+1 (comprising the five permanent members of the United Nations Security Council and Germany) was founded on an interim strategy where both sides adopted limited and reversible measures. Iran agreed to specific restrictions on its nuclear program, including limitations on enrichment levels and enhanced monitoring, while the US and its allies offered partial sanctions relief. This approach subsequently evolved into the 2015 Joint Comprehensive Plan of Action (JCPOA). The agreement imposed stringent limits on Iran’s uranium enrichment, capping it at 3.67 percent, while expanding International Atomic Energy Agency (IAEA) monitoring and providing sanctions relief in return for nuclear restraints. The implementation of the JCPOA followed a phased progression. The agreement was reached in July 2015, followed by Adoption Day in October, and then Implementation Day in January 2016, after the IAEA verified Iran’s initial nuclear commitments. Only after this verification did significant sanctions relief commence. The key takeaway from this experience is not that agreements based on sequencing are inherently doomed to fail. Rather, it is that sequencing without robust political guarantees is inherently vulnerable. When the US withdrew from the JCPOA in 2018 and reimposed sanctions, Iran concluded that technical commitments alone were insufficient. From Iran's perspective, the core issue became the lack of guarantees that a future agreement would withstand political shifts in Washington. The US, however, has its own apprehensions. American policymakers argue that sanctions relief must be tied to verifiable Iranian commitments, particularly concerning the nuclear program. They fear that providing economic benefits prematurely could diminish Washington's negotiating leverage. This argument forms the strongest objection to synchronized steps: critics assert that deep-seated mistrust renders simultaneous implementation impractical. They warn that Iran might exploit economic relief to bolster its capabilities, while Washington worries about losing its negotiating advantage. Yet, the solution is not to abandon reciprocity. Instead, the answer lies in designing more effective verification mechanisms. A viable model would not depend solely on trust but on verification. For instance, the reopening of the Strait of Hormuz could be coupled with a phased easing of restrictions, with each phase subject to third-party monitoring. Qatar, given its role as a mediator, could facilitate communication, while technical nuclear matters could remain under international verification by the IAEA. The underlying principle would be straightforward: every Iranian action would correspond to a clearly defined US response, and every US step would be matched by a measurable Iranian obligation. This strategy is more pragmatic than demanding unilateral concessions, as it affords both governments domestic political leeway. Neither side would appear to be capitulating under pressure; both could claim to be receiving reciprocal benefits. Recent diplomatic efforts have already partially moved in this direction. The memorandum of understanding signed in June between the US and Iran, with the backing of Qatar and other mediators, sought to establish mechanisms for de-escalating tensions, including issues related to military operations and freedom of navigation in the Strait of Hormuz. Subsequent discussions involved technical committees and monitoring mechanisms designed to manage implementation. Qatar's mediation has also grown increasingly crucial. Doha has strived to bridge the gap between Tehran's demand for confidence-building measures prior to negotiations and Washington's insistence on keeping nuclear issues at the forefront. The recent communication from US Vice President JD Vance to Iranian officials also reflected this predicament. Washington signaled a willingness to explore renewed negotiations but stressed that the nuclear issue must remain a central part of the discussion. Meanwhile, Tehran has continued to assert that pressure must be alleviated before broader talks can succeed. The question confronting both capitals, therefore, is not whether compromise is achievable, but whether they can devise a process wherein compromise is politically sustainable. The Middle East has already borne a significant cost for the conviction that pressure alone can yield strategic results. Military escalation, economic disruption, and energy uncertainty have underscored the limitations of confrontation. The next diplomatic challenge will not be determined by whether Iran or the US is willing to make the first concession, but by whether both sides are prepared to embrace a more arduous yet more practical formula: not trust preceding action, but verified action that progressively builds trust. The future of Iran-US diplomacy may hinge on replacing the politics of the first move with the discipline of the synchronized move.
