Iranian-backed militants in Iraq and Syria have launched over 60 attacks on bases housing U.S. personnel since Oct. 17, resulting in minor injuries to at least 60 U.S. personnel. The U.S. has responded with limited strikes on Iranian Revolutionary Guard sites in Syria, aiming to pressure Iran to stop the attacks. The U.S. is cautious about striking within Iraq to avoid alienating the Iraqi government. Critics argue that the U.S. response has failed to deter the groups and that more substantial retaliation is needed.
