Well, it isn't ISIS alone. In Syria, you have the Kurds fighting against islamists (ISIS and others), the Turks and against Assad, you have the Free Syrian Army fighting against ISIS and Assad, you have Assad, you have Russians, Iranians, Americans and maybe others I forgot. So defeating ISIS might be possible and is being worked on - however, finding a livable solution for the whole middle east, inclusing Lybia and Iraq, is on a whole different level.
