I don't know the numbers, though. They might be getting more people who are just showing up on their doorstep rather than people who are actively sought out and lulled into the group. The real danger, as the various attacks around the world have shown us, is converting an otherwise ordinary citizen into a harbinger of unspeakable atrocities in the place where they're living.
To address this internal threat, governments have been monitoring, monitoring, monitoring. Sure, do some more of that. There's no telling when intelligence will become crucial. No argument here. But these ISIS trolls still appear to be finding young people and convincing them of their ideology. This has got to stop.
Here's a radical suggestion: encourage high schoolers to reach out to ISIS.
Right now, ISIS is finding these young people around the world because they're easy to find. But what if there were 1,000,000 more fake personalities out there crying for help? It would be seriously difficult to find the real people susceptible to extremism with a deluge of fakers.
Our government doesn't have the time to pull off a plan like this. They don't have the manpower either. But teens? I can't think of a group with more time to kill. Train them, prepare them for craziness, let them pretend to be someone else online, and then hand over the fishing pole when they bring in a big fish.
With so many fake cases out there, it would be a complete waste of time for ISIS to scour the internet looking for real people. And if they found someone, how could they trust them with so many fakers out there?
This would effectively bring an end to local US enrollment (or any other government willing to do it). As for the rest of ISIS, I'll get back to you.
