We donu2019t, but ISISu2019s tactical and material position is so weak at this point that I suspect itu2019s more of an ideological network than a real one. Voices claiming to be ISIS with more or less legitimacy will claim responsibility for any attacks committed in the name of the highly toxic perversion of Islam it stands for, or can be plausibly represented as such.Unfortunately (and anxiously), I can see this going on for years after ISIS no longer exists. As the attackers become more and more loosely connected, theyu2019re going to be increasingly hard to spot before they strike. Theyu2019ll become invisible to police, in their communities, their congregations, even to their parents in the homes of their families.On the flip side of the coin. With the Jeremy Christian incident in Portland, Oregon, weu2019ve now seen what may be the first ideologically motivated Islamophobic murders. u201cYou call it terrorism, I call it patriotism!u201d he yelled in the courthouse. Christian is being depicted as a mentally disturbed individual who acted alone, but the same could be said of the perpetrator in the Westminster Bridge attack until u201cISISu201d claimed responsibility, and the woman in a niqab who attacked shoppers with a golf club and a knife in a Canadian shopping mall on the same day that the London Bridge attack took place. When police asked for her name, she said, u201cI am pledged to the true believers.u201d u201cISISu201d hasnu2019t claimed responsibility for that one, but it might as well.
