Last week, rockets landed in what was once known as the Green Zone—the heavily fortified neighborhood in western Baghdad where the American embassy is located. It was the second such attack since May, when another rocket exploded near the massive U.S. compound.
Then as now, the Trump administration thinks the attacks were the work of Shiite militias in Iraq with close ties to Iran. Washington has long called on the Iraqi government to clamp down on these Iranian proxy forces and cut off relations with Tehran.
The U.S. response to the latest attack will likely be to double down on those calls and dial up the pressure on Baghdad.
