アトムヴァッフェン・ディビジョン 非アメリカ支部
Two Atomwaffen members were arrested for threatening a prominent Argentinian LGBT activist and "forming a white supremacist association".
The attempted assassination of Cristina Fernández de Kirchner was inspired by Atomwaffen according to Tiempo Argentina.
Since the presidency of Jair Bolsonaro, Atomwaffen and other organizations have rapidly worked to create neo-Nazi cells, counting up to 330 as of 2019, this growth being even with the number of hate crimes. 
The offshoot of the Atomwaffen Division has been active since at least 2019, responsible for translating and disseminating propaganda in Portuguese and distribution of a manual for making explosive devices.
In May 2021, in the podcast "Infiltrado No Cast", presenter Ale Santos infiltrated an AWD Brasil chat, using false information, documenting the group's recruitment process.
In November 2023, Brazilian Intelligence Agency arrested seven men affiliated with Atomwaffen in an operation titled "Operation Accelerare". Around 100 civil police officers participated in the action. They are charged with participation in a criminal group and promoting Nazism. The men were allegedly leaders of the neo-nazi cells in Rio Grande do Sul and Ceará. The police also raided 23 addresses in Rio Grande do Sul, Curitiba, São Paulo, Araçoiaba da Serra, Ribeirão Pires and Fortaleza where they seized electronic devices, weapons and nazi paraphernalia.
During 2023, Brasil suffered a series of school shootings and attacks, some of them inspired by the Columbine Massacre and attacks carried out by neo-Nazis.
 As an example, Gabriel Rodrigues Castiglioni, perpetrator of two shootings that occurred in Aracruz, used to be active in Terrorgram Collective and during the shooting wore a swastika patch and Atomwaffen uniform. He confessed to being the perpetrator of the crime and stated that he planned it for two years. Furthermore, his father shared an image of the book Mein Kampf on social networks. The publication was deleted after the crime.
In September 2020, the Civil Guard and the Mossos d'Esquadra arrested two men in La Pobla de Cérvoles and El Campello, for planning terror attacks in order to provoke a "race war". Explosives and firearms were confiscated in the raid. The men had been involved with a project to create all-white rural community and stockpile firearms for the collapse of the society. Two months later, in December 2020, two men in Pamplona and Ronda were arrested for plotting similar terror attacks. According to the investigators the four men were involved with Atomwaffen Division and had produced Atomwaffen propaganda in Spanish. Besides stockpiling firearms and explosives, the men manufactured aphrodisiac psychoactive drugs. In addition to these late 2020 arrests, El Confidencial reported of two previous foiled terror attacks by affiliated men: A young man with 150 kilos of explosives planned to blow up the University of the Balearic Islands and a Mexican national living in Spain planned to attack a far-left demonstration with Asphyxiant gas.
Later in December 2023, the Spanish Civil Guard arrested 11 leaders and an additional 11 individuals are under investigation for belonging to a Nazi paramilitary group linked to Atomwaffen. Ten firearms, more than 9,000 cartridges, 34 bottles of sulfuric acid, explosive precursors, and numerous prohibited weapons were seized. The association had headquarters in the province of Málaga.
