However, one should not be fooled into thinking that everything will return to normal once the last IS stronghold is conquered and the last fighter has surrendered. This is merely one step in a larger struggle against jihadi terrorism.
Insurgency loomsOne reason to be cautious is that jihadi Salafism has become the driving ideology behind Islamic terrorism. Which, of course, does not mean every adherent of Salafism who wants to live as ancient Muslims did is automatically a terrorist. Indeed, there are plenty of apolitical Salafists. But there are also those who believe their Muslim utopia can and must be realized through violence.
IS may be on its last legs, but its ideological underpinnings are not. Followers of a militant Salafism could rise up once again. Experts say some 30,000 IS fighters have already gone underground in the past two years.
While some may want to return to regular life in their home countries, other may just be waiting for a fresh opportunity to wage an insurgency, which could present itself when warring parties inadvertently create a military vacuum, or when the US withdraws its troops from Syria. Jihadi fighters would quickly seize such an opportunity, just as they did in 2014.
Past rebirthIS, and the organizations that preceded it, have repeatedly been underestimated. When IS was defeated in 2008, few had any idea how many of its militants had gone underground in Iraq.
Three years later, the organization came back with a vengeance, as its leader had learned from previous mistakes and adapted to the new environment.
It will be no different this time. Then, like now, the militants will resort to typical guerrilla warfare, carrying out terror attacks and sowing fear. And they will attempt to terrorize the West as well. So we must be vigilant.

Youth need a brighter futureThere is only one effective method for combating terrorism: younger generations must enjoy better living conditions, must be given a voice and treated fairly. Otherwise, without a promising future, young people can resort to extremism and terrorism.
Haven retaken great swaths of land once under IS control is one step in this direction, as the group can now no longer entice desperate youth to live an "Islamic" life in its so-called caliphate.
