Recent discussion about white supremacy extremist groups has focused on the Russian Imperial Movement, but the Atomwaffen Division (AWD) deserves closer scrutiny for its transnational linkages and global aspirations. Atomwaffen members maintain links to Canada, Germany, Ukraine, Estonia, and elsewhere. Atomwaffen has cultivated linkages to other white supremacy extremist groups abroad, including the Sonnenkrieg Division, the Feuerkrieg Division, a German chapter labeled AWD Deutschland, and the Antipodean Resistance based in Australia. It is critical to counter the transnational growth of Atomwaffen before it is able to metastasize into a full-scale movement abroad, where it could draw upon an anonymous globalized network to organize and conduct terror attacks. Much of the recent discussion about white supremacy extremist (WSE) groups has focused on the Russian Imperial Movement (RIM), which is understandable, especially following its recent designation as a Specially Designated Global Terrorist (SDGT) entity by the United States Department of State. But another WSE group that deserves closer scrutiny is the Atomwaffen Division (AWD), because similar to RIM, AWD boasts transnational linkages and maintains global aspirations. Atomwaffen members maintain links to Canada, Germany, Ukraine, Estonia, and elsewhere. According to open source and AWD online propaganda, the organization maintains affiliates or inspired groups in over a dozen countries, many of which have threatened or planned to carry out acts of violence. AWD Deutschland in Germany has a so-called ‘kill list,’ which includes left-wing politicians, refugee and migrant worker advocates, and Jewish groups.
