Is the U.S.-Iran War Expanding?

Strikes and counter-strikes between the U.S. and Iran intensified on Thursday, increasing fears that the conflict may spread across the region. For the first time in five months, suspected military action expanded to Egypt through a drone strike, marking a new front in the war. While violence is escalating, these developments follow familiar trends. William Brangham reports that the intensification of these military engagements signals a potentially broader expansion of the ongoing U.S.-Iran war.
