Diplomacy
Trump addressed the nation at 9 p.m. ET on 1 April in his first formal prime-time speech since the war began. Hours earlier, he posted on Truth Social that Iran's president had asked the United States for a ceasefire. A spokesperson for Iranian President Masoud Pezeshkian called the claim "false and baseless." The Islamic Revolutionary Guard Corps issued a separate statement declaring the Strait of Hormuz "fully and decisively" under Iranian control.
Trump told Reuters he is "absolutely" considering withdrawing the United States from NATO and said he would voice his frustration with the alliance during the address. He singled out France, Poland and Britain for refusing to support the Iran campaign. Secretary of State Marco Rubio told Fox News that Washington would "have to reexamine" its relationship with NATO after the conflict ends.
Britain opened a different track. Prime Minister Keir Starmer announced on 1 April that 35 countries had signed a joint statement committing to restore maritime security in the Strait of Hormuz. Foreign Secretary Yvette Cooper will host the first meeting of those nations this week. Military planners will convene separately to assess operational options. Starmer said the strait's reopening "will not be easy" and would not happen automatically once fighting stopped. He drew a firm line on direct involvement: "This is not our war."
Türkiye continued to run parallel diplomatic tracks across multiple conflicts on the same day. On 31 March, Ukrainian Defence Minister Rustem Umerov met Turkish officials in Ankara on security cooperation and prisoner-of-war returns. Foreign Minister Hakan Fidan reviewed the state of negotiations with Ukraine's chief negotiator. On the same day, National Intelligence Organization chief Ibrahim Kalın met a Hamas delegation in Ankara to discuss Gaza. As Bosphorus News reported, Türkiye's ability to host Ukraine and Hamas contacts within a single day, while maintaining a separate channel in the Iran file, defines Ankara's current position as a multi-track diplomatic centre without being a party to any of the conflicts.
The Hormuz closure is reinforcing the energy architecture that bypassed Türkiye before the war began. The Cyprus-Egypt framework and Chevron's Aphrodite connection are gaining commercial urgency as European buyers accelerate the search for non-Gulf LNG. Cargo displaced by the Hormuz closure is moving through the Middle Corridor, where Türkiye sits as the western terminus. As Bosphorus News analysed, the TRIPP corridor and the Kars-Iğdır railway under construction in eastern Anatolia need to be read inside this dynamic.
NATO Cohesion
Trump's NATO withdrawal threat took concrete form on 1 April. He told The Telegraph the alliance was "beyond reconsideration" and confirmed to Reuters he was "absolutely" considering an exit. Legislation passed under the Biden administration requires two-thirds Senate approval for any withdrawal, maintaining a legal barrier. Trump's rhetoric is generating pressure to functionally sideline the alliance during an active campaign.
Starmer pushed back directly. He called NATO "the single most effective military alliance the world has ever seen" and dismissed external criticism as "noise" that would not influence British decision-making.
Germany drew its own line. Chancellor Friedrich Merz said Berlin would not contribute military assets to any Hormuz operation while the war continues. "We are not aware of any concept of how such an operation could be successful," he said.
Spain's continued closure of its bases and airspace to US Iran-linked operations is restructuring NATO logistics across the board. The importance of southeastern NATO infrastructure continues to grow inside that reconfiguration. Whether Türkiye permits US overflights linked to Operation Epic Fury remains publicly unresolved by either Ankara or Washington.
Maritime Security
Iranian strikes spread across multiple Gulf points on 1 April. A missile struck a fuel tanker leased to QatarEnergy in Qatari territorial waters. Qatar's defence ministry said three cruise missiles were launched from Iran, two intercepted and one hitting the vessel. All 21 crew members were safe and no environmental damage was reported. Separately, an Iranian drone hit fuel depots at Kuwait International Airport, causing a large fire.
UNCTAD published a rapid assessment on 1 April that puts the disruption in figures. Daily vessel transits through the Strait of Hormuz fell from approximately 130 in February to six in March, a 95 percent decline. Global merchandise trade growth is projected to slow from 4.7 percent last year to between 1.5 and 2 percent in 2026. An estimated 20,000 seafarers remain aboard vessels in the active conflict zone, with the International Maritime Organization negotiating evacuations with all parties.
Iran's parliament approved a plan to charge vessels crossing the Strait of Hormuz a transit toll on 1 April. The decision institutionalises Tehran's control over the waterway as a revenue and political instrument, separate from its military use of the strait as a pressure point.
Israel-Lebanon Front
Israeli strikes hit Beirut on 1 April. An airstrike on the Jnah neighbourhood killed at least five people and wounded 21, Lebanon's Health Ministry said. A separate strike on a vehicle in Khaldeh, just south of the capital, killed two more. The Israeli military said both operations targeted senior Hezbollah figures. Hezbollah confirmed the death of Haj Youssef Ismail Hashem, commander of the group's southern Lebanese front, calling him "a beacon of the Islamic Resistance." Hashem is the most senior Hezbollah commander killed since Lebanon was drawn into the war on 2 March.
Israeli Defence Minister Israel Katz stated in the clearest terms yet that Israel intends to maintain security control of southern Lebanon up to the Litani River after the current operation ends. Lebanese Defence Minister Michel Menassa called the declaration "a deepening of the aggression." UN aid chief Tom Fletcher told the Security Council that southern Lebanon risked becoming "another occupied territory in the Middle East."
The UN Security Council held an emergency session on 1 April following the deaths of three Indonesian UNIFIL peacekeepers in two separate incidents. Ten European countries issued a joint statement calling for the safety of UN forces to be guaranteed. A UN security source told AFP that Israeli fire killed one peacekeeper on Sunday, while a mine may have caused Monday's explosion. The investigation remains open.
***Trump's claim that Iran's president requested a ceasefire was denied by Iranian officials and has not been independently confirmed. Attribution for the three UNIFIL deaths has not been established and the investigation is ongoing. The full list of 35 nations in the Starmer coalition has not been published.
