US-Iran deal leaves core sticking points unresolved - and a $300bn question

June 18, 2026

The United States and Iran have signed a memorandum of understanding that temporarily reopens the Strait of Hormuz and establishes a 60-day negotiation window to pursue a comprehensive peace agreement. While President Trump has portrayed this as a major diplomatic victory that prevents Iran from developing nuclear weapons, the actual agreement only commits Iran to reducing its enriched uranium stockpile under international supervision, leaving critical details unresolved. The deal has drawn criticism from members of Trump's own party who argue it gives too much to Iran without securing sufficient concessions, particularly regarding nuclear capabilities, proxy militias, and missile programs.

Who is affected

  • President Donald Trump and Vice-President JD Vance
  • The United States and Iran (both governments and populations)
  • International Atomic Energy Agency (IAEA)
  • Israel and Prime Minister Benjamin Netanyahu
  • Hezbollah and other Iranian-backed proxy groups
  • Regional partners involved in potential reconstruction funding
  • Congressional lawmakers demanding briefings
  • Senator Bill Cassidy and other Republican critics
  • Trump's anti-interventionist base (Maga supporters)
  • The Obama administration (referenced comparatively)

What action is being taken

  • Iran is "downblending" its stockpile of highly enriched uranium under IAEA supervision
  • The Strait of Hormuz is being reopened
  • A cessation of hostilities extending to Hezbollah is in effect
  • US officials are conducting calls with reporters to release details
  • Lawmakers in Congress are demanding briefings and information from the Trump administration
  • The two countries have commenced a 60-day negotiation period for a comprehensive agreement

Why it matters

  • This agreement represents a significant shift in US-Iran relations and has major geopolitical implications for Middle East stability and global energy security. The reopening of the Strait of Hormuz, a critical waterway for global oil shipments, immediately affects international energy markets and commerce. The deal's success or failure will shape Trump's foreign policy legacy and determine whether the region moves toward lasting peace or returns to military confrontation. The political ramifications are substantial, as the agreement's ambiguities regarding financial commitments and nuclear restrictions could undermine Trump's domestic support and contradict his campaign promises of non-intervention and fiscal restraint toward adversaries.

What's next

  • A formal signing is scheduled to take place on Friday
  • The two countries have 60 days to negotiate a comprehensive final peace agreement
  • Technical details regarding uranium downblending, including methods and timeline, must be worked out during the 60-day negotiation period
  • The US will work with regional partners to develop a plan regarding the $300 billion reconstruction funding
  • The 60-day deadline is subject to possible extension if necessary
  • If negotiations fail, Trump has indicated the US will resume military action ("go back to bombing")
