It looks very much like the shooting of four Marines at the Navy Marine Corps Reserve Center in Chattanooga, Tennessee on July 16 was motivated by radical Islam. The shooter, Mohammod Yousef Abdulazeez, reportedly posted on his short-lived blog on Islam two posts referring to preparing for death through Islam. He praised the Sahaba (the followers of Muhammed) for waging jihad. (The blog has since been taken down.)

A Tweet associated with ISIS appeared to some to point to a connection with the Syrian/Iraqi jihadist army, and several news outlets ran with the connection before it became evident that the Tweet had actually been posted three hours after the shooting. There is presently no evidence of any direct link between Abulazeez and ISIS. Undoubtedly, ISIS would love to claim credit; they are very, very good at information operations. It would only build their legend further.

But that is the nature of modern, open-source warfare. There might be a connection, there might not. Converging methods and interests. It may be discovered (though it will probably always be a matter of guesswork, as Abdulazeez is dead) that he was, in fact, inspired to conduct the attack by way of ISIS propaganda. But there doesn’t have to be a direct chain of command, and there probably isn’t. All that is needed is motivation and means. And the reality of modern globalization means that there is no shortage of motivation.

There are those who are saying that this is another reason why ISIS has to be destroyed. I’m not objecting to the head-choppers getting slaughtered wholesale. But it won’t end the problem. It’s far, far too late for that.

Even if ISIS disappeared tomorrow, it is by no means the only jihadist organization out there. They are not the first, and they won’t be the last.  ISIS may have eclipsed al-Qaeda (at least in the Western imagination) for power and savagery, but AQ is still out there. So is Hezbollah. Tomorrow there will probably be a new group that wasn’t happy with how hardcore the last one was. Jihad, like many ideologies, is a hydra. Destroy one group, two more crop up in its place. The more you try to find the one HVT whose death or capture will bring down the whole monster, the more decentralized the foe becomes.

And apart from the organized terrorist groups, there are small groups or singletons who become “inspired” by the religious hate of a radical mullah or imam, or simply by the propaganda videos that have swamped the Internet for the last decade and a half. How is that going to be fixed? Ban Islam? Religions tend to become more entrenched when persecuted. Censor the Internet? Welcome to the Deep Web, where you can find all sorts of illegal stuff, up to and including classified ads for assassinations. There is no practical way, in the modern world (or during any period, for that matter), to prevent every violent incident. Can’t be done.

It can even be argued that in trying to do so, the target society actually becomes more vulnerable. Take a look at this photo from CNN:
