World leaders and senior US lawmakers on 20 June broadly welcomed a Memorandum of Understanding signed between the United States and Iran, with supporters calling it a breakthrough that could reopen the Strait of Hormuz, ease regional tensions, and advance negotiations over Tehran's nuclear programme.
What the Memorandum Covers
The White House said President Donald Trump and Vice President JD Vance had secured the agreement, which commits Iran to never obtaining a nuclear weapon, reopens the Strait of Hormuz to free navigation, and establishes a framework for future diplomacy. The accord also provides for an immediate and permanent ceasefire, according to a statement from UN Secretary-General António Guterres' spokesman, who described it as 'a critical step towards the peaceful settlement of the conflict.'
G7 and European Response
A joint statement from G7 leaders welcomed what they called 'the breakthrough and the opportunity that currently exist in the Middle East', describing the agreement as 'an historic opportunity to prevent Iran from acquiring any nuclear weapon and tackling the threats related to its regional and ballistic activities.' The leaders said they stood ready to support its implementation.
British Prime Minister Keir Starmer called the accord 'a hugely important step forward in ending the war, ensuring regional stability and re-opening the Strait of Hormuz', congratulating Trump and mediators from Pakistan, Qatar, and other countries involved. European Commission President Ursula von der Leyen said the agreement should mean 'a definitive end to Iran's nuclear programme', adding: 'The Strait will reopen. Oil prices are falling. And that's how diplomacy delivers.'
French President Emmanuel Macron said the agreement 'paves the way for lasting peace and allows the reopening of the Strait of Hormuz', while German Chancellor Friedrich Merz called it 'an opportunity — for the stability of the region and for the global economy.' Japanese Prime Minister Sanae Takaichi welcomed the cessation of hostilities and stressed that 'free and safe navigation in the Strait of Hormuz be promptly resumed', expressing hope that future talks would lead to a final settlement of Iran's nuclear issue.
Regional Voices
Qatar's Ministry of Foreign Affairs welcomed the signing, saying it reflected both sides' commitment to resolving differences through negotiation and peaceful means while promoting regional stability and economic growth. Switzerland described the memorandum as 'an important step toward de-escalation in the region.' Notably, Qatar and Pakistan were among the key mediators credited with facilitating the agreement.
US Congressional Reaction
Republican lawmakers broadly backed the accord. Senate Republican Conference Chairman John Barrasso said Trump had brought Iran to the table 'from a position of American strength.' Senator Lindsey Graham called the signing 'an essential step' that could help create 'a pathway to peace well beyond the Iranian conflict.' Senator Rand Paul stated: 'This war must end. I stand with President Trump on peace.'
In the House of Representatives, Representative Robert Aderholt said the deal would reopen the Strait and require Iran to abandon its nuclear programme, while Representative Andy Harris described it as 'a remarkable day for America and the world.' The accord now moves toward implementation, with the framework for further negotiations expected to take shape in the coming weeks.
Point of View
Enforceable nuclear agreement is where every previous Iran deal has either succeeded or unravelled. The Strait of Hormuz dimension adds economic urgency: falling oil prices on the news are a market vote of confidence, but markets have been wrong on Middle East diplomacy before. The real test will be whether the 'framework for future negotiations' produces binding commitments on enrichment limits and inspection access — the hard specifics that past accords have struggled to lock in.
