On Wednesday, the U.S. said that its war with Iran has only just begun. The war expanded again as Iran fired a drone into NATO territory, and the U.S. used a torpedo fired by a submarine to sink a warship for the first time since World War II. The U.S. says it has struck more than 2,000 targets and Iran’s health ministry says more than 920 people there have been killed. Nick Schifrin reports.
