Scholars have long seen radicalisation as a predominantly group based phenomenon, occurring largely through ‘real world,’ in person interaction. By contrast, the internet is seen as playing only a limited ‘facilitating’ role in radicalising people to violence. However, a series of attacks by far right extremists over the past decade has demonstrated that this perspective is less accurate than it once was. Almost none of these terrorists were members of extremist groups and had only engaged with other extremists on the internet. In this article, we examine the relative importance of face-to-face group interaction and physically isolated internet-based radicalization in driving individuals towards extremist violence. We do so through a detailed case study of Action Zealandia, New Zealand’s leading ideological white nationalist group. The study is based on eighteen months of infiltration of the group by one of the authors from 2019 to 2021. When interacting online, members often adopt highly extremist personas, in some cases threatening mass violence. By contrast, face to face interaction and group membership pushed the group away from extremist violence. This was due to several factors: police pressure and a lack of opportunity for the movement to grow, and the often uninspiring nature of offline interaction.

Book review: This edited volume offers a collection of essays on the timely topic of online violent extremism, including: terrorists’ wide ranging use of online platforms, the appeal of online platforms, internet use in terrorism trials, online extremist narrative and counter-narrative studies, the need for and the challenges associated with online violent extremism research particularly from an audience perspective.

The public outcry attending President Trump’s attempted travel ban from seven radical Muslim states, designed to prevent foreign terrorists from entering the country, has diverted attention from the longstanding danger of homegrown jihadists. As early as 2007, the New York Police Department (NYPD) released a 92-page report documenting the extent of al-Qaeda-linked homegrown jihad in Europe and the United States.[1] The Obama administration, however, went out of its way to ignore, deny, and whitewash any homegrown terror that smacked of Islamist violence. But a decade later, al-Qaeda has been all but eclipsed by the Islamic State (ISIS), which has skillfully used social media to become the foremost purveyor of jihadist indoctrination in the West, creating a “virtual caliphate,” extremely dangerous and easily accessible to vulnerable men and women from a variety of backgrounds in a manner al-Qaeda was never able to achieve. Even were all territory now under ISIS control to be retaken, this virtual caliphate could continue to pose a major threat.

Extremism has been a problematic term to define and suggests different and opposing meanings. This study explores how Twitter users conceptualize extremism in Arabic and express their opinions/arguments to construct the term. A corpus of tweets was collected from Twitter API using the word ‘تطرف أو متطرف’ in Arabic for extremist/extremism. A topic modeling algorithm was then applied to the dataset to uncover latent associated concepts underlying extremism, followed by a critical discourse analysis using Van Dijk’s Sociocognitive approach. The discursive and linguistic strategies used by Twitter users to support and justify their views of extremism were examined. The findings demonstrate an ideological influence that controls the concept of extremism, keeping it open to manipulation to serve shared interests and goals. Arab users of Twitter use extremism to promote their groups’ positive schema against others-negative schema.

Until his death in a U.S. drone strike in August 2015, Junaid Hussain was the Islamic State’s most prolific Englishlanguage social media propagandist, working to incite and guide sympathizers in the United Kingdom, United States, and beyond to launch terrorist attacks. Before joining the
jihad in Syria, Hussain was part of a hacking collective in the United Kingdom, focusing much of his attention on perceived injustices against Muslims. In many respects, he was well integrated into British society with his family home in a leafy suburb of Birmingham. A spell in prison contributed to his radicalization and his decision to move to Syria, where he married fellow extremist Sally Jones.

Many prevention and countering of violent extremism experts place too much emphasis on the radicalising power of online mass distributed messaging by violent extremist groups. Instead, Nafees Hamid argues that radicalisation takes place in a social ecology within which the messaging of terrorist groups plays only a small role. This article shows that people are resistant to mass persuasion and that certain environments are more conducive to the spread of extremist messaging. Small-group dynamics are useful to explain the spread of ideas and that altering these dynamics can provide a buffer against some ideas while enabling others.
