The dream of a liberation is now a reality,” Iraqi Prime Minister Haider al-Abadi proclaimed last week, when his forces drove ISIS from a few final strongholds. Abadi’s declaration of victory did not seem unwarranted. After three years, Iraqi and Kurdish fighters, backed by an 80-country U.S.-led coalition, have reclaimed all of the territory ISIS once controlled in Iraq and the key cities it held in Syria. The Islamic State no longer has much of a claim to calling itself a state at all.

But the victory is incomplete—and not just when it comes to the challenges of ISIS-inspired lone-wolf attacks, foreign fighters returning home from Iraq and Syria, and  the persistence of ISIS franchises elsewhere. While such concerns are real, a more dangerous scenario also deserves some attention: ISIS could resurrect its caliphate where it was born, in Iraq and Syria. It has been planning for such a resurrection since at least 2016, and quietly preparing since well before losing Raqqa in October.

Most ominously, ISIS has a tried-and-true playbook for bringing itself back from near death. Just a few years ago, it managed to resurrect itself after apparent defeat. And the history of that resurrection should serve as a warning of what may be coming now.
