Ceasefire Stalls as Iran’s Internal Power Struggle Shapes Negotiations

The United States extended its ceasefire with Iran while a second round of talks in Islamabad was canceled after Tehran failed to submit a unified proposal, underscoring an intra-regime struggle between IRGC figures like Esmail Vahidi and parliamentary leadership. Iran-backed Iraqi militias continue drone attacks on Gulf states, Hezbollah has clashed with Israeli forces as tensions rise across the region, and the US-Israel campaign against Iran’s drone/missile programs proceeds with sanctions and strikes on bases such as Bid Ganeh. CENTCOM also reports maritime interdictions and vessel turnbacks to enforce the blockade of Iranian ports. Some Iranian clerics publicly advocate diplomacy, but hardliners and broader regional actors appear prepared for renewed hostilities, keeping escalation risks high.
