The United States seems to be succeeding in putting more and more pressure on ISIS. Although it is far from clear when ISIS will be defeated in either Syria or Iraq, the combination of anti-ISIS forces in each country now seems likely to inflict a series of steady defeats, and ISIS may lose control of a number of major population centers at some point between the end of the year and mid-2017.

Any such victory, however, depends on the various anti-ISIS factions in Syria and Iraq avoiding deeper conflict among themselves. Victory also will be limited even in terms of the defeat of ISIS. Many ISIS fighters will escape. ISIS already has cells and affiliates in other countries. And—just as Al Qa’ida in Mesopotamia transformed itself into ISIS—there will still be movements committed to equally violent forms of Islamist extremism such as the Al Nusra Front. The “war against terrorism” will go on, perhaps focusing even more on outside states, while the vengeful fighters will disperse to other countries.
