Through a months-long squabbling and blaming, the USA and Iran has finally agreed to give peace a chance. The deal, if succeeds and ends in win-win situation for the involved actors, it would also lead towards the virtual end of approximately four decades of active hostility among them.
While peeping through the announced framework for the US-Iran peace deal—brokered under the “Islamabad MoU” umbrella and set for an official signing ceremony in Switzerland—marks an astonishing breakthrough to end over three months of active warfare. By establishing an immediate and permanent halt to military operations, unblocking the United States naval blockade, and reopening the critical Strait of Hormuz, the agreement has already stabilized global energy markets and triggered a wave of optimism.
However, looking beneath the immediate relief, evaluating the longevity and durability of this deal requires balancing the rapid diplomatic momentum against deep-seated structural vulnerabilities.
High-Stakes Economic Imperatives
For Iran, the conflict and subsequent naval blockade inflicted massive economic strain. The prospect of unfreezing $12 billion to $24 billion in frozen overseas assets and the eventual phasing out of crushing sanctions provide a profound incentive for Tehran to adhere to the initial terms. Conversely, for the U.S. and global markets, the immediate drop in oil prices and the removal of inflationary threats stemming from a closed Strait of Hormuz offer a massive political and economic win that Washington will want to preserve.
Broad Domestic Consensus within Iran
Unlike the 2015 JCPOA, which was heavily fractured by internal Iranian politics between moderates and hardliners, U.S. intelligence and regional observers note a rare, broad consensus spanning the Islamic Revolutionary Guard Corps (IRGC), civilian leadership, and conservative figures like parliamentary speaker Mohammad Bagher Ghalibaf. Because the hardline establishment is actively leading the negotiations, the deal faces less threat of being sabotaged by internal regime infighting. Irrespective of the 2015 JCPOA, the current threat to the likely negotiated peace deals stems from the USA and not the vice versa. Almost all major stakeholders and power centers are involved in the initiative, therefore, substantial chances that the peace deal may not be derailed by the Iranian side. However, given the nature and temperament of Donald Trump, there are fears that he may annul all with one sweeping statement.
Comprehensive Regional Scope
Past agreements suffered because they ignored regional proxy dynamics. This framework notably includes provisions for an immediate termination of military operations in Lebanon (targeting the Israel-Hezbollah front). Treating the crisis as an interconnected regional conflict rather than an isolated bilateral issue heavily reinforces its structural integrity.
Major Threats to Durability
Despite these promising foundations, several critical fault lines threaten to fracture the deal during its upcoming implementation phase:
The Perilous 60-Day “Technical Negotiation” Window
The agreement signed is a framework to end the active war, not a fully realized treaty. It triggers a volatile 60-day window to negotiate the most contentious, unresolved issues—most notably the complete dismantling of Iran’s nuclear program and the extraction of its weapons-grade enriched uranium. Bridging the gap between the U.S. demand for complete denuclearization and Iran’s historical insistence on nuclear sovereignty will be a monumental task.
Trump’s “Ultimate Alternative” & Hair-Trigger Snapbacks
President Donald Trump has explicitly warned that the U.S. retains its “ultimate alternative” (military force) and will resume attacks if Iran fails to reach a final nuclear accord within the stipulated timeline. Furthermore, Vice President JD Vance emphasized a strict “no compliance, no cash” stance, stating that economic benefits will only flow after Iran proves it has met its obligations. This transactional, high-pressure approach leaves almost zero margin for error or minor compliance delays. This in fact leaves many doubts in ordinary minds about the utility and longevity of the deal. As discussed in the preceding paras, the controversial personality of Donald Trump shall be at the center of all fuss if the he falters and fails in maturing his commitments.
De-mining and Verification Friction
The physical durability of the deal relies on immediate operational trust. Here are some known conditions agreed so far for confidence building measures. Iran is expected to clear its mines from the Strait of Hormuz within the first 30 days while the U.S. rolls back its blockade. Any localized miscalculation, accidental naval skirmish, or dispute over verification protocols during this high-friction period could reignite hostilities before the technical talks even begin. The deal is singed on a tight rope to walk and a slight wandering may land the parties in the same quagmire.
The Spoiler Risk (Israel and Proxies)
While the deal reportedly encompasses the Lebanon front, regional dynamics remain a wild card. If radical factions or non-state actors outside the direct command structure of Tehran execute rogue attacks, or if Israel deems the nuclear dismantling provisions insufficient, external military actions could quickly derail the fragile peace. This is a volatile point as the history proves Israel as an unguided horse often seen trampling upon the vicinities of the Arab world, particularly, the Middle East. If this unguided horse is not reigned then the developments would refuel and this time with great intensity, certainty and planning. Nevertheless, any hegemonic attempt on the part of any party may isolate its standing in the comity of nations.
The US-Iran peace deal possesses strong short-term viability because both nations desperately required an off-ramp from a devastating regional war, and the immediate reopening of global shipping lanes provides immense mutual benefit.
However, its long-term durability is highly fragile. The agreement functions essentially as a high-pressure ticking clock. If the two sides cannot codify a permanent solution for Iran’s nuclear material and proxy funding within the upcoming 60-day technical window, the peace framework risks becoming a temporary pause rather than a permanent settlement.
There is another side of the story; if Iran roams sanction free that may propel and usher it in the prospects of development more than any other regional country thereby multiplying its power to an unprecedented level thereby diminishing the role of other countries like Kingdom of Saudi Arabia to peanuts. Nevertheless, the peace deal will ensure and pave the way for stable and viable region which has all potential to become global trade hub in the years to come.
