The U.S. has reimposed a naval blockade on Iran and intensified its airstrike campaign in retaliation for Tehran’s attacks on ships trying to pass through the Strait of Hormuz. Iranian officials said the American strikes on Wednesday hit an Iranian army barracks, killed at least seven troops and wounded hundreds of people across the country. Mac McCorkle, from the Duke University Sanford School of Public Policy, joined Jeff Hamlin to discuss the latest developments in Iran.
