On the 16th day of Operation Epic Fury, the United States military announced a significant intelligence breakthrough by reverse-engineering captured Iranian drones. This development is expected to bolster defenses against Tehran's unmanned aerial capabilities. Simultaneously, the Pentagon issued a formal nuclear warning to Iran, signaling a heightened level of strategic deterrence. President Trump stated that while Iran appears to be seeking a ceasefire, current terms remain unacceptable, and he reiterated threats of further strikes on Kharg Island. The global economic impact remains severe as Iran's blockade of the Strait of Hormuz continues to disrupt one-fifth of the world's oil transit. In response, India has placed its navy on standby to escort merchant vessels, and President Trump has urged a multinational coalition—including China, France, and Britain—to deploy warships to reopen the waterway. Regionally, the conflict has triggered a humanitarian crisis in Pakistan, where war-fueled inflation has caused a surge in food prices and civil unrest. On the tactical front, the conflict has expanded geographically. Hezbollah launched dozens of rockets from Lebanon into Israel, while U.S. strikes reportedly hit targets in Shiraz and Isfahan, resulting in at least 15 civilian casualties at a factory. Domestically, Iran has moved to arrest 20 individuals accused of spying for Israel. Amidst these escalations, the U.S. has authorized a $10 million bounty for information on Iranian leadership, focusing on high-level regime figures like potential successor Mojtaba Khamenei.
