White Terrorism Shows ‘Stunning’ Parallels to Islamic State’s Rise (Published 2019)
Like Islamic State recruits, white nationalists are attracted to an apocalyptic ideology spread through social media.

Many scholars of terrorism see worrying similarities between the rise of the Islamic State and that of white nationalist terrorism, seen most recently in the carnage in El Paso, Tex. "The parallels are stunning," said Will McCants, a prominent expert in the field. And they are growing more notable with each new attack.
Experts say that the similarities are far from a coincidence. White nationalist terrorism is following a progression eerily similar to that of jihadism under the leadership of the Islamic State, in ways that do much to explain why the attacks have suddenly grown so frequent and deadly. In both, there is the apocalyptic ideology that predicts — and promises to hasten — a civilizational conflict that will consume the world. There is theatrical, indiscriminate violence that will supposedly bring about this final battle, but often does little more than grant the killer a brief flash of empowerment and win attention for the cause. There are self-starter recruits who, gathering in social media's dark corners, drive their own radicalization. And for these recruits, the official ideology may serve simply as an outlet for existing tendencies toward hatred and violence.

The feedback loop of radicalization and violence, once triggered, can take on a terrible momentum all its own, with each attack boosting the online radicalization and doomsday ideology that, in turn, drive more attacks.
The lessons are concerning. It is nearly impossible to eradicate a movement animated by ideas and decentralized social networks. Nor is it easy to prevent attacks when the perpetrators' ideology makes nearly any target as good as the next, and requires little more training or guidance than opening a web forum.
And global changes that played a role in allowing the rise of the Islamic State are only accelerating, Mr. Berger warned — changes like the proliferation of social networks.
