U.S. President Donald Trump said he would make a "final determination" but left unsigned a tentative memorandum of understanding reached between U.S. and Iranian negotiators to extend a fragile ceasefire and reopen the Strait of Hormuz. The draft would extend the early-April truce for 60 days, lift a U.S. naval blockade on Iranian ports and allow shipping through Hormuz while teams negotiate more contentious issues including Iran’s nuclear programme, sanctions relief and frozen assets. Trump reiterated red lines — Tehran must never obtain a nuclear weapon, mines must be cleared and the strait reopened without tolls — demands Tehran has publicly rejected. Iranian state media and officials said no final deal has been agreed. Limited strikes and drone incidents this week, including exchanges near Bandar Abbas, underscored the ceasefire's fragility. U.S. defence officials have warned Washington remains capable of resuming hostilities if diplomacy fails. Markets reacted to the reporting, with oil prices easing on the prospect of Hormuz reopening but significant hurdles remain, including sequencing of nuclear safeguards, sanctions relief and Lebanon-related security concerns.

President Donald Trump has offered to replace a string of musical acts who cancelled appearances at the White House-backed Freedom 250 “Great American State Fair,” saying he may give a major speech or stage an “AMERICA IS BACK” rally on the National Mall. The multi-week fair, organised by Freedom 250 to mark the United States’ 250th anniversary, is due to run late June into July; organisers said Trump will now kick off the opening ceremony on June 24. Several performers including Young MC, Morris Day and The Time, the Commodores, Martina McBride and Bret Michaels publicly withdrew this week, saying they were misled about the event’s political ties or citing safety concerns. A handful of acts — notably Vanilla Ice, Flo Rida, Fab Morvan and C+C Music Factory’s Freedom Williams — remain on the bill. Trump posted on his Truth Social account disparaging the artists as “third rate,” suggested cancelling musical performances altogether and ordered aides to assess the feasibility of holding a rally in place of concerts. Freedom 250 insists the fair is nonpartisan; critics point to the group’s Trump-era origins and leadership. The controversy has raised questions about security, logistics and the political framing of national commemorations.

Australia, the United States and the United Kingdom announced on May 31, 2026, that Canberra will acquire three in-service Virginia-class nuclear-powered submarines from the US rather than the previously planned mix of two used boats and one new vessel. The decision, disclosed at the Shangri-La Dialogue in Singapore and confirmed by Defence Minister Richard Marles alongside US Defence Secretary Pete Hegseth and UK Defence Secretary John Healey, is presented as a move to “streamline” the AUKUS submarine programme, simplify logistics and realise cost savings. Canberra expects the first Virginia-class to arrive in the early 2030s (previous schedules indicated 2032) with further deliveries over the following years; under the 2021 AUKUS framework Australia was to receive at least three US submarines within 15 years. Officials cited US shipyard production constraints and the benefits of operating a single variant for training, maintenance and supply chains. Critics warn the second-hand boats will be less capable and have shorter service lives than new Block upgrades, and questions remain about whether US fleet requirements and industrial capacity will allow the planned transfers without affecting American readiness.

An Iranian ballistic missile struck near the Ali Al Salem air base in Kuwait on May 30, 2026, injuring about five Americans — a mix of U.S. service members and contractors — and damaging two MQ-9 Reaper strike drones, one of which was destroyed. Kuwaiti air defences intercepted the Fateh-110 missile, but falling debris hit the base, causing the casualties and equipment losses; MQ-9s are valued at roughly $30 million each. The incident occurred as U.S. and Iranian envoys weighed a possible extension of a fragile ceasefire. A White House Situation Room meeting on May 29 ended without an announcement, despite President Donald Trump saying he was prepared to make a “final determination” on a preliminary deal that Washington says would require Iranian concessions on its nuclear programme and reopening the Strait of Hormuz. U.S. officials said the strike represents a ceasefire violation and comes amid ongoing tit-for-tat strikes across the region. The attack has added urgency to talks while raising fresh concerns about munitions depletion, costly equipment losses and the security of strategic shipping lanes.

US media reported on May 30-31 that President Donald Trump asked aides to amend a proposed memorandum of understanding that would pause the US‑Israel military campaign against Iran and begin talks on Tehran’s nuclear programme. The White House Situation Room meeting lasted about two hours; officials told outlets the president sought tougher language on handling Iran’s enriched uranium stockpile, clearer timing and mechanics for transfer or disposal of material, and firmer guarantees on reopening the Strait of Hormuz for unrestricted shipping. Trump also raised concerns about provisions that could involve unfreezing Iranian funds. The revised draft was sent back to Tehran for consideration, with US officials estimating a response could take several days. Negotiators had reportedly agreed a 60‑day window to negotiate nuclear commitments and sanctions relief, but final approval awaits sign‑off by Trump and Iran’s supreme leader, complicating and potentially lengthening talks. Iranian leaders have reiterated demands for tangible results before making concessions.
