Professor Paul Rogers has a short commentary that opens with:
In the ashes of the caliphate lie the seeds of a new and even more dangerous ISIS.

(Concludes) But it does indicate the sheer amount of knowledge and expertise that ISIS and related groups accrued in this latest phase of conflict. Far from disappearing, these will be put to use in perhaps unexpected ways. It is another reason why the "war on terror", even as it takes different forms, is likely to continue.
