Young people, overwelmingly white and male, have become involved in a global network of Neo-Nazi extremist groups that plot mass violence online. A 21-year old planted a bomb outside the Western Union office in Lithuania's capital, Vilnius. There are also lesser-known groups with more directly violent aims that follow an ideology called 'Accelerationism' - The belief that carrying out bombings, mass shootings, and other attacks is necessary to hasten the colapse of society and allow a white ethnostate to rise in its place.                                                                                                                                                                                                                                                                                                                                                                                                  Experts trace the origins of groups like these to a neo-nazi website called Iron March that went offline in 2017, and which notoriously helped extremists from many countries forge international connections and spread  accelerationist propaganda. The ideology has been linked to the 2019 Christchurch massacre in New Zealand, where a white nationalist killed 51 people at two mosques while livestreaming the attack online, and a shooting earlier this year at a supermarket in Buffalo, New York where 10 people were killed.                                                                                                                                                                                                                                                                                                                                                Reporters gained access to two dozen internal chat groups linked to a broader network of neo-nazi accelerationists. In chat logs that reporters reviewed, members showed off homemade explosives, encouraged one another to kill minorities, and discussed how to get access to weapons. The scores of messages and propoganda in these chats provide a glimpse into one of the most dangerous corners of modern far-right extremism. It is increasingly international, intent on radicalizing young people, and committed to using violence to further its fascist ideology.                                                                                                                                                                                                                                                                                              Unlike extremist groups that want to integrate their beliefs into political parties or run for local office, the aim of accelerationist groups like these is primarily to create violent chaos. Rather than functioning as organized groups, they act as banners under which people can make connections, share resources, and radicalize one another. "We need to think about them like marketing brands, rather than operational entities," Newhouse said.  Youth radicalization is one of the primary goals of the movement.                                                                                                                                                                                                                                                                                                                                                                                                      Neo-Nazis have tried to target online spaces where they can recruit isolated young people, and they have infiltrated gaming platforms such as Minecraft and Roblox that are immensely popular with kids. "They are intentionally trying to find 14 to 18 year olds and turn them into terrorists," Newhouse said. "It's so transnational at this point. We found accelerationists in Brazil and Argentina and Japan, China and /South Africa. It's all over the place."                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  Numerous countries have designated accelorationist groups as terrorist entities, which gives them broader powers to investigate and charge anyone suspected of affiliating with them. Law inforcement agencies across North America and Europe have deployed undercover agents to infiltrate chat groups, as with Christian Michael Mackey in Grand Prairie, Texas. While some countries have instituted large-scale government decentralization programs, most governments have no such system. Countries that have attempted such efforts have struggled  with the complicated nature of addressing mental illness and belief in extremist ideology at scale. What's left is a sort of game of whack-a-mole in which authorities try to shut down networks and prosecute individuals, only to have new groups spring up and leaders emerge.                                                                                                       INSIDER - Nick Robins Early, Alexander Nabert, Christina Brause
