Albeit possibly a less violent one. The struggle and "self-sacrifice" in combat against "the great satan" is more important than who is "winning", again there are deep psychological issues that it takes a certain environment and circumstances to create and ISIS is just the flavor of the week in the context of thousands of years of human conflict, mass movements and atrocities. Suicide bombers and the people that bomb abortion clinics are the same only wrapped up in different causes. They are both true believers, swap their locale and the result is the same.
The vigor of a mass movement stems from the propensity of its followers for united action and self-sacrifice. When we ascribe the success of a movement to its faith, doctrine, propaganda, leadership, ruthlessness and so on, we are but referring to instruments of unification and to means used to inculcate a readiness for self-sacrifice.
