The fragile peace between Iran and the United States has unravelled with startling speed. In a dramatic reversal of hopes raised by the signing of a 14-point interim agreement just under two weeks ago, both nations have resumed military operations across the Persian Gulf, trading accusations of ceasefire violations while threatening far graver consequences. The collapse of the nascent deal exposes the deep mistrust that continues to define relations between Washington and Tehran, with each side interpreting the other's military actions as provocative breaches of good faith.
The latest escalation began when United States Central Command announced it had conducted fresh strikes against Iranian military facilities in response to what it characterised as ongoing Iranian attacks on commercial shipping in the vital Strait of Hormuz. American forces targeted Iranian surveillance systems, communications infrastructure, air defence networks, and facilities used for storing drones and laying naval mines. The strikes came shortly after a Panama-flagged tanker was attacked by an Iranian drone, continuing a pattern of incidents that have plagued one of the world's most critical maritime chokepoints. For Washington, these operations represented necessary enforcement of the ceasefire terms, demonstrating resolve to protect international shipping lanes.
Iran responded with overwhelming force and rhetoric. Hours after United States President Donald Trump warned on social media that America might "militarily complete the job" started in February and that "the Islamic Republic of Iran will no longer exist," the Iranian Islamic Revolutionary Guard Corps launched a coordinated barrage of missiles and drones targeting American military installations in Kuwait and Bahrain. Kuwaiti air defences activated to counter incoming projectiles, while sirens wailed across Bahrain as residents sought shelter. The Guard Corps framed its operations as a proportionate response to American violations of the ceasefire, vowing that Washington's bases would "experience hell in the coming days."
The accusations flowing between capitals reveal the fundamental disagreements undermining the agreement. Iran contends that the United States, despite signing the accord, has failed to uphold its obligations to enforce a complete cessation of hostilities throughout the region. Tehran specifically points to Israeli military operations in southern Lebanon against Hezbollah, an Iran-backed militia, arguing that Washington tacitly permits these strikes by failing to pressure its ally. The United States, conversely, insists that Iran has consistently attacked shipping and American facilities, thus breaching the very arrangement both sides committed to honouring. These competing narratives suggest that neither party genuinely abandoned its strategic objectives when signing the interim deal.
The negotiations that produced the 14-point agreement had taken place in Switzerland just one week prior, with mediation conducted by United States Vice President JD Vance and Iran's parliamentary speaker, Mohammad Baqer Qalibaf. Following those talks, Washington lifted certain sanctions on Tehran as a gesture of goodwill. Yet the period since has seen mounting tensions rather than consolidation of peace. The agreement was designed to halt the four-month conflict that erupted on February 28 when United States and Israeli forces initiated military operations, while simultaneously reopening the Strait of Hormuz to international commerce and creating space for discussions on deeper issues such as Iran's nuclear programme. None of these objectives appears within reach now.
The Strait of Hormuz remains at the heart of the regional competition. Before the conflict began, this narrow waterway carried roughly one-fifth of globally traded oil and liquefied natural gas, making it irreplaceable to the international economy. During months of active hostilities, Iran had effectively blockaded the passage, trapping hundreds of vessels laden with cargo inside the Persian Gulf. As the ceasefire took hold, shipping companies cautiously began moving these accumulated tankers and container vessels through the strait, triggering a rapid decline in oil prices that reflected the surge in available supply. Yet this nascent reopening now faces jeopardy from renewed military operations and counter-operations.
The struggle for control of the strait reveals divergent strategic interests that no interim agreement can easily reconcile. Washington has promoted a southern shipping corridor that runs along the Omani coast, keeping vessels away from Iranian territorial waters and reducing Tehran's leverage over global commerce. Iran, however, seeks to establish a northern route that passes through its own maritime domain, positioning itself as an essential and potentially lucrative authority through which the world's energy supplies must flow. This fundamental disagreement about the legitimate use of the strait transcends ceasefire language and reflects competing visions of regional power and influence.
Israeli military operations in Lebanon add another layer of complexity to the unravelling agreement. On Sunday, Israel announced it had struck Hezbollah militants in the southern Lebanese district of Nabatieh, destroying rocket launchers and killing armed fighters. This continued a pattern of incursions that Israel initiated in March as part of its campaign against the Iranian-backed militant organisation. Iran views these operations as violations of the ceasefire terms, since the agreement implicitly obligated the United States to ensure that its Israeli ally would cease military operations. Israel, which was never formally a party to the Iran-United States accord, maintains its right to pursue military objectives against groups it designates as threats. The result is a disagreement about whether the ceasefire extends to proxy conflicts or applies only to direct United States-Iran hostilities.
Lebanese efforts to establish stability through successive ceasefire agreements have proven ineffectual. The most recent arrangement was brokered by Washington on Friday, yet fighting continued almost immediately. Hezbollah refuses to disarm unless Israeli troops withdraw from Lebanese territory they have occupied, while Israel insists that it will not relinquish control of seized areas until Hezbollah poses no military threat. These contradictory demands mean that any ceasefire in Lebanon remains temporary and fragile, dependent upon constant international mediation and vulnerable to collapse when either side perceives a strategic opportunity.
The broader Middle Eastern security architecture, already strained by years of United States-Iran antagonism, faces renewed destabilisation from this renewed cycle of escalation. Regional states including Saudi Arabia, the United Arab Emirates, and other Gulf monarchies have watched carefully as negotiations proceeded, hoping that a United States-Iran accommodation might reduce the volatility that has characterised their region. Instead, they now confront a situation potentially more dangerous than before the deal was signed, because both sides have already demonstrated their unwillingness to abide by mutually agreed constraints. The credibility of mediation efforts, whether conducted by the United Nations, regional powers, or the United States itself, has been damaged by the rapid deterioration of the latest arrangement.
SEA shipping companies operating through the Strait of Hormuz face mounting commercial and security pressures as military operations resume. The CMA CGM shipping corporation hailed the transit of its Galapagos container ship through the strait as "an important milestone," yet that milestone appears increasingly precarious. Insurers will likely demand higher premiums for vessels traversing these waters, companies may reroute shipments at greater expense and delay, and the anticipated recovery in global supply that prompted oil prices to decline will stall if attacks and counter-attacks escalate further. The economic costs of geopolitical instability in this region are distributed across global supply chains and energy consumers worldwide.
For Malaysia and Southeast Asian readers, the renewed instability in the Persian Gulf carries direct economic implications. The region remains dependent on Middle Eastern energy supplies, and disruptions to the Strait of Hormuz flow ultimately through to petroleum and natural gas prices in Southeast Asia. Additionally, Malaysia's substantial shipping and maritime industries depend on unimpeded passage through critical chokepoints, making regional stability an essential factor in economic planning and commercial viability. The failure of the United States and Iran to maintain their ceasefire agreement suggests that the region will remain volatile for the foreseeable future, requiring careful navigation by nations seeking to maintain commercial and diplomatic relationships across the Gulf divide.
The trajectory of the coming weeks appears set toward further deterioration unless both parties fundamentally alter their approach. The United States has signalled its willingness to escalate beyond recent strikes, while Iran has matched American rhetoric with promises of expanded military operations. The structures created by the interim agreement lack enforcement mechanisms beyond mutual accusations and recriminations. Without a meaningful shift in the underlying interests driving United States and Iranian competition for regional influence, the ceasefire appears destined to remain a temporary pause rather than the foundation for lasting peace. The challenge now lies in whether either side possesses sufficient political will or diplomatic incentive to reverse course and rebuild confidence in the arrangement they so recently signed.
