The New Year’s Eve attack on the U.S. Embassy compound in Baghdad has exposed a deepening divide between the United States and Iraq over Iran’s role there, even as the Pentagon embarks on a more aggressive mission to counter Iranian influence across the Mideast. “The game has changed,” Defense Secretary Mark Esper said Thursday, telling reporters that violent acts by Iran-backed Shiite militias in Iraq — including a rocket attack on Dec. 27 that killed one American — will be met with U.S. military force. Esper said they are “defensive support” that can be used if there is more trouble in Baghdad or elsewhere in the region.
