U.S. Challenges Iran’s Border Closure Claims as Diplomatic Deadline Looms
Tehran signals maritime leverage while the Trump administration maintains conditional sanctions relief and military pressure.
Tensions between Washington and Tehran escalated over the last 24 hours as Iran’s joint military command declared the Strait of Hormuz 'closed' in response to Israeli military activity in Lebanon. U.S. Central Command quickly disputed the claim, asserting that the critical energy transit route remains open and that global shipping traffic continues to flow under U.S. monitoring. The maritime friction comes as Iranian officials express renewed skepticism regarding the current interim deal, framing the upcoming Switzerland summit as a demand for U.S. compliance rather than a diplomatic breakthrough.
The Trump administration has signaled a dual-track approach of conditional diplomacy backed by military deterrence. Vice President JD Vance emphasized that the current memorandum allows the U.S. to adjust sanctions relief based on Iran's adherence to international inspections and its cessation of support for regional proxies. President Trump further heightened the stakes by issuing a 60-day ultimatum for a lasting deal, while simultaneously pressing Israel to accept a ceasefire in Lebanon to prevent regional escalation from derailing the nuclear negotiations.
On the ground, continued Israeli strikes in southern Lebanon remain a significant diplomatic hurdle, with Iranian leadership conditioning further progress on the cessation of attacks against Hezbollah. While the Iranian Foreign Ministry continues to route consultations through mediators, Deputy Foreign Minister Saeed Khatibzadeh stated that Tehran intends to manage shipping services in coordination with Oman during the 60-day interim period. The next round of formal negotiations is expected to take place between Tuesday and Thursday.
