U.S. Intensifies Airstrikes on Iran; Trump Warns of Infrastructure Attacks

The conflict between the United States and Iran escalated sharply on July 15 as U.S. Central Command (CENTCOM) conducted a fifth day of airstrikes targeting Iranian military assets. The 90-minute offensive focused on coastal defense systems and cruise missile storage on Greater Tunb Island, as well as three sites in Bushehr, the city housing Iran’s civilian nuclear power plant. In a significant policy shift, President Trump announced the reimposition of a total naval blockade on all Iranian ports, abandoning a previous plan to charge tolls in the Strait of Hormuz. The President further warned that if negotiations do not resume, the U.S. will begin targeting Iranian civilian infrastructure, including bridges and power plants, as early as next week. Iran has responded with both military and diplomatic escalation. The Islamic Revolutionary Guard Corps (IRGC) warned it would halt all energy exports from the Middle East, stating that regional resources would be "denied to all" if Iran is blocked from the market. This follows Iranian missile attacks on U.S. allies in Kuwait, Bahrain, and Jordan on July 14. Iranian officials described the current state of hostilities as an "existential war" and reported that the latest strikes resulted in 262 casualties, including two confirmed deaths. The economic fallout of the escalation is intensifying, with global crude oil prices rising to nearly $80 a barrel. The U.S. Treasury Department complemented the military action by sanctioning a network of 50 individuals, vessels, and nations—including Russia and Nigeria—accused of facilitating IRGC illicit activities and weapon procurement. While the White House has not dismissed the possibility of deploying ground troops to force a diplomatic resolution, it continues to focus on degrading Iran's maritime strike capabilities and exerting maximum economic pressure through the newly reinstated blockade.
