Iran warned on May 10 that its military would deliver a 'decisive and immediate response' if France and Britain deployed forces to the Strait of Hormuz. French President Emmanuel Macron responded by assuring that France had 'never considered' such a deployment.
Maritime tensions have intensified in the Strait of Hormuz with attacks involving drones, contributing to security concerns and the need for international coordination on protecting shipping lanes.
Israeli Prime Minister Benjamin Netanyahu stated that the war that began on February 28 has accomplished much but is not finished because enriched uranium and uranium enrichment sites remain in Iran that must be removed and dismantled. When asked how Israel would remove the uranium from Iran, Netanyahu responded that 'we go and remove it.'
Iran submitted a written response to US proposals aimed at ending the war that began on February 28. The Iranian response was not publicly detailed but Iranian state media indicated it emphasized Iran's fundamental national rights and included demands for war reparations, sanctions relief, unfreezing of assets, and control of the Strait of Hormuz. Iran stated willingness to suspend uranium enrichment but for a period shorter than the 20-year moratorium proposed by the US, and refused to dismantle nuclear facilities.
US President Donald Trump rejected Iran's written response to American peace proposals on May 10, posting on Truth Social that the Iranian response was 'totally unacceptable' and that 'Iran has been leading the United States and the rest of the world on for 47 years.' Trump did not specify which aspects of the proposal were unacceptable, but his rejection indicates the fundamental impasse between the two sides remains unresolved.
According to the Wall Street Journal, the question of Iran's nuclear program is expected to be negotiated over the course of the next 30 days, indicating ongoing diplomatic efforts focused on resolving disputes over uranium enrichment and nuclear facilities.
French and British defense ministers will co-chair a videoconference meeting on Tuesday with counterparts from approximately 40 countries willing to contribute to a mission to secure the Strait of Hormuz. The meeting aims to discuss and define military contributions to a defensive mission to reopen and secure the strait when conditions permit.
U.S. Ambassador to the United Nations Mike Waltz stated that Trump is giving diplomacy "every chance we possibly can before going back to hostilities." Energy Secretary Wright indicated that if negotiations do not show promise in the coming days, the U.S. would resume military operations to open the strait.
The United Nations nuclear agency reports Iran has more than 440 kilograms of uranium enriched to 60% purity, which is a short technical step from weapons-grade material. The majority of this highly enriched uranium is likely located at Iran's Isfahan nuclear complex.
An Iranian military spokesperson stated forces were on "full readiness" to protect sites where uranium is stored. The spokesperson said Iran considered it possible that the U.S. or Israel might attempt to steal enriched uranium through infiltration or helicopter-borne operations.
Israeli Prime Minister Benjamin Netanyahu said in a CBS interview that the war cannot end while enriched uranium remains in Iran. Netanyahu stated that Trump told him "I want to go in there" and that he believes uranium removal can be accomplished physically.
Iran and armed allied groups like Hezbollah in Lebanon have used drones to carry out hundreds of strikes since the war began with U.S. and Israeli attacks on February 28.
President Trump posted on social media that he rejected Iran's response to the latest U.S. peace proposal for ending the conflict, calling it "TOTALLY UNACCEPTABLE." Trump accused Iran of "playing games" with the United States and stated "They will be laughing no longer!"
Iran delivered a multi-page response to the U.S. peace proposal, demanding an end to the blockade, unrestricted oil exports, sanctions relief, release of frozen assets, a ceasefire in Lebanon, and continued Iranian control over the Strait of Hormuz. On nuclear issues, Iran agreed to export some highly enriched uranium to a third country and dilute the rest, agreed to an enrichment pause but rejected a 20-year moratorium, and refused to dismantle existing enrichment facilities.
Iran's deputy foreign minister warned that any French or British vessels supporting maritime security in the Strait of Hormuz after hostilities end would be met with "a decisive and immediate response from the armed forces." France's President Macron responded by clarifying it would be a civilian international mission to secure shipping, not a military deployment.
Two unidentified objects struck the South Korean-operated vessel HMM NAMU while anchored in the Strait of Hormuz, about one minute apart, causing an explosion and fire. South Korea's investigation found the objects were likely the cause but has yet to determine who was responsible.
Russian President Vladimir Putin said that Moscow's proposal to take enriched uranium from Iran to help negotiate a settlement remains on the table as part of ongoing diplomatic efforts.
The U.S. military has blockaded Iranian ports since April 13, turning back 61 commercial vessels and disabling four. On Friday, the U.S. struck two Iranian oil tankers it said were attempting to breach the blockade. Iran has largely blocked the Strait of Hormuz since the war began on February 28.
The fragile ceasefire faced test when a drone ignited a small fire on a ship off Qatar. The United Arab Emirates and Kuwait reported drones entering their airspace. The UAE shot down two drones and blamed Iran. No casualties were reported, and no one immediately claimed responsibility. Qatar called the ship attack a "dangerous and unacceptable escalation that threatens maritime trade routes."
Iran's new supreme leader, Mojtaba Khamenei, met with the head of the joint military command and issued "new and decisive directives for the continuation of operations and the powerful confrontation with the enemies," according to state media. Khamenei has remained out of public view since the war began.
