Well no; my last sentence was quite explicit about their aim being world domination. Al-Baghdadi, the ISIS leader, has been quite open about wanting a global caliphate. That why western Jihadis travel to the middle east to join them. That's what makes them qualitatively different than ANC, IRA, ETA etc. And that's why we should take them very seriously. If they were to get hold of weapons of mass destruction, they would use them.
