The cease-fire agreement between the United States and Iran, announced last month to facilitate the reopening of the Strait of Hormuz, has largely unraveled amid ongoing military operations and escalating tensions. The memorandum of understanding, signed on June 17, established a 60-day deadline for negotiating limits on Iran’s nuclear program in exchange for economic relief. However, most provisions of the deal have been violated, with both sides accusing the other of breaching terms, and President Donald Trump himself declaring the agreement effectively over.

The cease-fire aimed to halt military activity on all fronts, including in Lebanon, and to ensure the territorial integrity and sovereignty of Lebanon. Despite this, military operations persist. The U.S. has conducted airstrikes targeting Iranian positions for nearly two consecutive weeks, while Iran continues to retaliate by targeting countries hosting American troops—actions that have resulted in the deaths of 18 U.S. service members since the conflict began on February 28. In Lebanon, Israeli forces have maintained strikes against Hezbollah targets despite the cease-fire, with the militant group responding through attacks on Israeli troops in southern Lebanon.

Efforts to respect each other’s sovereignty, as outlined in the agreement, have faltered, and substantive negotiations toward a comprehensive deal appear stalled. With less than three weeks remaining before the 60-day window expires, no major talks have transpired. U.S. Secretary of State Marco Rubio characterized Iran as lacking seriousness in negotiations, warning that the United States would act to protect its interests and those of its allies if necessary.

The memorandum also called for the removal of the U.S. naval blockade within 30 days, allowing for the uninhibited passage of commercial vessels through the Strait of Hormuz. However, after attacks on commercial oil and gas ships in early July—attacks Tehran did not claim responsibility for but blamed on U.S. actions—the United States reinstated the blockade on July 13. This development has severely limited commercial shipping, with maritime tracking data showing only six vessels passing through the strait recently, compared to a pre-conflict average of roughly 130 per day.

Economic provisions of the deal, such as waiving U.S. sanctions on Iranian oil sales and releasing frozen Iranian assets, have also encountered obstacles. President Trump’s administration initially granted temporary licenses allowing Iran to sell oil, but these were rescinded following attacks in the strait. Iran denies any agreement to allow the U.S. to control or monitor the use of its unfrozen assets. Vice President JD Vance has emphasized that reconstruction funding would depend on Iran ending its nuclear program and submitting to rigorous inspections, tying economic relief directly to nuclear negotiations.

On the nuclear front, the agreement reiterated Iran’s commitment not to develop nuclear weapons and called for a mutually agreed framework for managing enriched material and monitoring compliance. Nonetheless, no progress has been made in nuclear talks since the cease-fire’s breakdown. Experts note that previous international deals on Iran’s nuclear program took years to devise, rendering rapid resolution unlikely.

Efforts to establish a mechanism for monitoring compliance and implementing the memorandum have not materialized. While mediators from Pakistan and Qatar continue to work toward reducing hostilities, meaningful diplomacy has yet to resume.

Separately, the Pentagon has revised its reporting on U.S. military casualties in the ongoing conflict with Iran following criticism over transparency. The number of wounded U.S. service members since July 7 has been updated to 207, an increase of 142 from earlier reports, while the total fatalities remain at 18. These figures are now categorized under a new “overseas operations casualties” designation, complicating efforts to assess the full human cost of the conflict. Critics, including lawmakers, have called for a more comprehensive and timely accounting of U.S. casualties amidst the continuing military engagements in the region.

As the cease-fire agreement approaches its expiration, the prospects for a final deal that addresses the complex issues of military activity, economic sanctions, and nuclear limitations remain uncertain, with significant diplomatic and security challenges ahead.
