The ongoing peace talks between the United States and Iran in Islamabad, Pakistan, ended on April 12, 2026, without a conclusive agreement, leaving a 15-day ceasefire in place until April 21. Sources from the Pakistani government indicate that this ceasefire will be respected, with no violations expected during this period. Pakistan has emerged as a key guarantor, leveraging its military presence in the Gulf to exert pressure on Iran. The US peace proposal remains on the table, but discussions broke down primarily over Iran's refusal to halt its nuclear weapons development, with the US demanding 'zero enrichment' and the removal of Iran's uranium stockpile. The control over the strategic Strait of Hormuz also remains a contentious issue. Iran's position is complicated by the need to avoid further economic sanctions and military escalation, particularly with the Saudi-Pakistan military alliance strengthening. As a result, both sides are expected to exercise restraint until the ceasefire deadline, with the hope that diplomatic efforts can resume thereafter.
