The proposed US-Iran peace deal remains on a knife edge despite positive signals from both sides. US President Donald Trump has said an agreement could be signed "over the weekend," while Iranian Foreign Minister Abbas Araghchi stated that a deal has "never been closer." However, key sticking points remain, including Iran's demands over the Strait of Hormuz, a Lebanon ceasefire, and future nuclear negotiations. Israel, which has been kept out of the talks, continues to oppose concessions and insists Iran must never acquire nuclear weapons.
