THE ADMINISTRATION OF President Donald Trump promised to "restore deterrence" against Iran when it assassinated Iranian spymaster Gen. Qassem Soleimani outside Baghdad International Airport on January 3. But months later, the Iraqi militias formerly armed, trained, and advised by Soleimani seem undeterred, and American troops in Iraq find themselves in an escalating cycle of conflict with no end in sight.
In March, militia forces fired a barrage of Katyusha rockets at Camp Taji, killing a U.S. Army soldier, a U.S. Air Force airman, and a British servicewoman.
A local militia close to Iranian intelligence services called Kata'ib Hezbollah appeared to take credit for the attack in a social media diatribe invoking the "right to resist" America's "malicious project of occupation."
American forces responded with what the Pentagon calls "precision defensive strikes" against five Kata'ib Hezbollah weapons depots. Iraq accused the U.S. military of killing Iraqi soldiers and civilians instead of Kata'ib Hezbollah members during the raids, aggravating already strained U.S.-Iraqi tensions. The following weekend, Katyusha rockets slammed into Camp Taji again in broad daylight.
Assassinating Soleimani was supposed to have prevented attacks like these, yet that act was also the result of escalating retaliation: In December, a rocket killed an American translator in Iraq. The Trump administration blamed Kata'ib Hezbollah (though the Iraqi government has since cast doubt on that claim), and U.S. forces retaliated with a round of strikes that killed 25 members of the militia.
In response, the Iraqi militia incited its supporters to ransack the U.S. Embassy in Baghdad. Trump called the incident his "Anti-Benghazi," referring to the deadly 2012 attack on a U.S. consulate in Libya. And then he ordered Soleimani killed.
Iran responded by firing ballistic missiles at a U.S. airbase in Iraq, injuring more than 100 U.S. troops. Meanwhile, the Iraqi parliament passed a nonbinding resolution asking American forces to leave the country.
The Trump administration initially justified the assassination by claiming that Soleimani posed an "imminent threat" to American lives, but it was later unable to identify any specific threat posed by Soleimani. The administration then gradually changed its justification to "restoring deterrence" against Iran.
