US-Iran War: Diplomatic Talks Stall as Conflict Enters Second Month
Diplomatic efforts to end the US-Iran war have stalled after Iran formally rejected a 15-point American ceasefire proposal, as the conflict — which began on 28 February 2026 — continues to reshape global energy markets and draw in regional powers.
The war, codenamed 'Operation Epic Fury' by US Central Command, has seen extensive American and Israeli airstrikes targeting Iranian military infrastructure, nuclear facilities, and industrial sites. Iran has responded with ballistic missile and drone attacks on Israel and US military bases across the Gulf region.
Key Developments
On 24 March, the United States presented a 15-point ceasefire proposal to Iran via Pakistan, demanding that Tehran dismantle its nuclear programme, end uranium enrichment, limit its missile capabilities, cease support for allied militant groups, and ensure freedom of navigation through the Strait of Hormuz. The proposal also called for a month-long ceasefire to allow negotiations to proceed.
Iran rejected the proposal on 26 March, reiterating its own conditions for a ceasefire: a complete cessation of US and Israeli attacks, compensation for wartime damages, an end to strikes on allied forces, and international recognition of Iranian authority over the Strait of Hormuz. The White House responded by threatening further military action if Iran did not agree to a deal.
By 25 March, US CENTCOM Commander Admiral Brad Cooper stated that the combined US-Israeli force had struck over 10,000 sites across Iran since the war began, claiming to have destroyed more than two-thirds of Iran's missile, drone, and naval production facilities.
Background
The conflict began on 28 February 2026 with simultaneous US and Israeli strikes targeting Iran's nuclear and ballistic missile programmes. The UK government confirmed on 1 March that US forces could use British military bases at Diego Garcia and RAF Fairford for a "specific and limited defensive purpose" to intercept Iranian missiles. UK aircraft have been deployed in a defensive role in Qatar, Jordan, Iraq, and Cyprus.
The war has had significant economic consequences globally, with Iran's effective closure of the Strait of Hormuz pushing Brent crude above $116 a barrel and driving energy price surges across Europe, including in the UK and Ireland.
Why It Matters
The conflict has direct implications for the UK and Ireland, with rising energy costs already feeding into higher inflation on both sides of the Irish Sea. The UK's involvement through the use of its military bases has also drawn Britain into the geopolitical fallout, with questions being raised in Westminster about the extent of British commitment to the US-led operation.
What's Next
Diplomatic channels remain open, with Pakistan continuing to act as an intermediary. Russia has been reported to be providing modified drone components and satellite imagery to Iran, complicating the international response.
