Sources familiar with mediation efforts say the United States and Iran may be closer to an understanding than public statements suggest, despite not holding a second round of talks in Pakistan. Intensive behind the scenes diplomacy is ongoing, with mediators working to narrow remaining gaps.

Current discussions center on a phased framework that would first restore conditions to those that existed before the war and reopen the Strait of Hormuz without restrictions or toll charges. Iran’s nuclear program, which Washington and Israel cite as the main reason for military action, would be addressed in a later stage of negotiations.

Iran has conveyed the proposal through Pakistani intermediaries. President Donald Trump has insisted that any agreement must include Iran surrendering its stockpile of near weapons grade uranium and ending uranium enrichment, demands Tehran has repeatedly rejected.

Mediators are increasing pressure on both sides as the coming days are seen as critical. The diplomatic push is overshadowed by the possibility that Washington could abandon talks and resume military action, while Israel has warned that easing restrictions in the Strait of Hormuz could be viewed by Tehran as a sign of weakness.
