Diplomatic efforts between the United States and Iran are stalling as a two-week ceasefire approaches its Wednesday expiration date. Iranian officials, including Parliament Speaker Mohammad Bagher Ghalibaf, have indicated that a final agreement remains distant despite ongoing talks. The situation is further complicated by Supreme Leader Ayatollah Mojtaba Khamenei’s warning that Iran’s navy is prepared for military confrontation, signaling Tehran's readiness for the expiration of the truce. On the water, the U.S. continues to strictly enforce a naval blockade. U.S. Central Command reports that 23 ships have been turned back toward Iran since Monday. In response, Iran has re-closed the Strait of Hormuz, a critical transit point for one-fifth of the world's oil supply. The Revolutionary Guard warned that any vessel attempting to cross will be considered an enemy combatant and targeted, a move that has caused significant volatility in global energy markets. The regional stability is further pressured by the deterioration of a separate U.S.-brokered ceasefire between Israel and Lebanon. Fresh Israeli strikes against perceived threats south of the "yellow line" have raised fears of a broader conflict. Iranian Deputy Foreign Minister Saeed Khatibzadeh warned that continued U.S. insistence on the blockade is a "miscalculation" that risks the collapse of the entire regional ceasefire package.
