Khalilzad Describes Fragile Progress in US-Iran Tensions Amid Shift to Negotiations

Zalmay Khalilzad posted on social media late Monday that US-Iran tensions have shifted toward a combination of fighting and negotiations, describing the change as fragile progress.

He cited recent developments including a five-week ceasefire, the reopening of the Strait of Hormuz to all international shipping, renewed talks between Washington and Tehran on issues of mutual concern, and US President Donald Trump's agreement to delay a previously threatened escalation.

Khalilzad said obstacles persist, with Iran insisting on guarantees preventing a return to war in any agreement. The US, he noted, wants to preserve the option of resuming hostilities if negotiations fail.

Khalilzad proposed that both sides commit not to return to war during the negotiations. He added that Iran has previously accused the US of launching attacks during ongoing negotiations.
