Ted Kaczynski, better known as the Unabomber, was an American domestic terrorist whose 17-year bombing campaign killed three people and injured 23 others. Seeking to protect wilderness and destroy technology, he targeted scientists and businessmen. Kiernan Christ writes “Kaczynski’s contemporary influence, however, is not strongest among environmental activists. Rather, his manifesto and ideology have found a home on far-right websites, where Kaczynski is cited as a key radicalizing influence and thought leader in spaces generally extremely hostile to modern environmentalism.”

My colleagues and I outlined a plan to combat extremism in the military. It focuses on prevention over law enforcement by leveraging existing support programs for those at risk of joining extremist groups.

Although social media companies have taken steps to address the proliferation of domestic extremist content online, continued reports have identified that violent groups continue to operate on the platforms, and racially or ethnically motivated violent extremists (RMVEs), anti-government and conspiracy-related content and targeted ads remain on these platforms.

On 12 August 2021, Jake Davison embarked on a killing spree that resulted in the deaths of five people before taking his own life. Davison’s digital footprint on social media platforms contains numerous examples of misogynistic and anti-feminist attitudes, as well as references to the incel subculture. What are incels? And should we consider their ideology an extremist one related to the far-right?

Twenty years ago this month the United States experienced the scary anthrax letter attacks, which targeted major media outlets and members of Congress.

Extremist ideas inspire violence in a few, but for the many, participation increasingly resembles a consequence-free game separate from reality. “As technologies develop further, either in the form of Facebook’s metaverse or other forms of mixed or augmented reality that blur the line between online and offline, the potential disconnect between play and real-world violence is only going to grow more acute,” experts say.

In the United States, 743,452 “excess” (potentially preventable) deaths occurred from COVID-19 between February 2020 and September 4th, 2021, according to the CDC National Center for Health Statistics. This figure exceeds the number of excess deaths that occurred during the 1918-19 influenza pandemic, which was caused by an even deadlier virus.

U.S. national security and law enforcement agencies are battling what they describe as a “significant jump” in threats from domestic terrorists, many of whom are acting on their own and motivated by racial animosity or anti-government ideology.

As strange as it may sound, revolutionary Islamist groups suffer from recruitment problems as any other organization does. My research on Islamist terrorism has found that al-Qaida and its rival offshoot, the Islamic State group, have long had chronic difficulties replenishing their ranks.
