Have US-Iran talks failed? Why no deal yet doesn’t mean diplomacy is dead

US-Iran diplomacy remains in a deadlock as efforts to translate a fragile ceasefire into a permanent agreement have stalled. A planned visit by US envoys to Islamabad was cancelled due to excessive demands from both sides, particularly over Iran's nuclear programme and control of the Strait of Hormuz. Diplomats say the impasse reflects a slowdown in negotiations rather than a collapse, with both sides remaining steadfast in their positions.
