James Mason (James Nolan Mason, born July 25, 1952) is an American neo-Nazi writer whose collected newsletter essays, published as Siege in 1992, became the foundational accelerationist text for Atomwaffen Division and the wider "Siege Culture" movement. He grew up in Chillicothe, Ohio, joined the youth movement of the American Nazi Party at fourteen, and from 1980 to 1986 wrote the monthly newsletter Siege for the National Socialist Liberation Front.¹ The essays argue that democratic institutions are too corrupt to reform, that lone attackers are difficult for authorities to police, and that tensions should be escalated until a race war becomes unavoidable.² Mason served a Colorado prison sentence in the mid-1990s and stayed out of the public eye until the text was revived on the Iron March forum in 2015.³⁴

Youth and the American Nazi Party

Mason joined the youth movement of the American Nazi Party (ANP) under George Lincoln Rockwell at fourteen. According to the finding aid for his papers at the University of Kansas, he left school at sixteen to work at the party's headquarters in Arlington, Virginia.¹ The Southern Poverty Law Center profile dates his move to the Virginia headquarters to 1968, when William Luther Pierce recommended that he come there and learn printing, and records that he became a full party member in 1970 before returning to Chillicothe.⁵

After Rockwell was shot dead in 1967 the party fragmented. Mason affiliated with its successor, the National Socialist White People's Party, and later with the National Socialist Liberation Front (NSLF), which was led by Joseph Tommasi.¹ The group had its roots in a 1970s periodical created by Tommasi, and Mason served as one of its leaders.² ProPublica describes the NSLF as a splinter group of the ANP that formed in 1969 and espoused the strategic use of political terrorism.⁶ Tommasi was shot dead in 1975 outside the party's headquarters in El Monte, California.⁵ The International Centre for Counter-Terrorism study states that after the killing Mason helped re-establish the NSLF and its newsletter.²

The SPLC profile also records that in 1973 Mason and an associate took a car on a test drive and maced several Black teenagers in a Dairy Queen parking lot, and that Mason served six months in a Cincinnati workhouse for the car offense.⁵

The Newsletter and the NSLF

Siege was published monthly from August 1980 until June 1986, in hand-circulated and mailed form.² The finding aid states that the NSLF had become defunct by 1982 and that Mason continued producing the newsletter until 1986.¹ The SPLC profile gives a different sequence: it records that leadership of the NSLF passed to Karl Hand in 1981, places the group's end in 1986, when Hand was arrested for attempted murder, and says Mason left in 1982 after a dispute over his praise of Charles Manson.⁵ Between 1978 and 1980 the same profile has Mason working with the National Socialist White Workers Party and editing its newspaper before the 1980 revival.⁵

ProPublica reported that in the newsletter Mason proposed a White Liberation Front of small armed squads that would "hide in wilderness areas" and strike in "hit-and-run engagements." In Mason's view, Dan White, who assassinated San Francisco Mayor George Moscone and gay civil rights leader Harvey Milk, was a hero.⁶

The 1992 Book

Mason had failed for years to find a publisher. Michael J. Moynihan's Storm Books first released the collected essays in 1992 as Siege: The Collected Writings of James Mason.² The ICCT study counts 217 of the op-ed style pieces in the book and gives the first edition a length of 434 pages.² The Open Library record for a 1992 Storm Books edition issued in Denver, Colorado credits Michael M. Jenkins as editor and introducer.⁷ The SPLC profile credits Moynihan with editing the newsletters into the book, and dates the edition to 1993.⁵ ProPublica describes the book as 563 pages, a figure that the ICCT study links to the 2017 edition.⁶

Tom Metzger praised and distributed the book, and much of the neo-Nazi movement of the period ignored or criticized it. Later printings followed in 2003, 2017 and 2018, and the 2018 edition ran to 684 pages through the self-publishing service CreateSpace.² The SPLC profile records that in 2003 Ryan Schuster reprinted the book with a new introduction through his Black Sun Press in Bozeman, Montana.⁵ Bethan Johnson and Matthew Feldman wrote that the Iron March moderators published a first revision in June 2015, that a third edition under the Iron March imprint in September 2017 added a six-page preface by Mason after members of Atomwaffen Division located him, and that Mason wrote more than three dozen new pieces in 2017 and 2018 for a Siege Culture website before it was taken down. They describe a fourth edition in 2018 with nearly 200 pages of added material, including statements by the imprisoned AWD leaders Brandon Russell and John Cameron Denton.⁸

Universal Order and Charles Manson

From the early 1980s Mason corresponded with Sandra Good and Lynette Fromme, two followers of Charles Manson then imprisoned, and then with Manson himself. With Manson he founded Universal Order, which he intended as a self-sustaining ideology rather than an organization with members and buildings. His preference, according to the finding aid, was to wait for "the system" to consume and destroy itself from within.¹ The SPLC profile dates Universal Order to 1982. The Counter Extremism Project places its formation in the 1970s and states that Manson designed the movement's logo, a swastika over scales of justice.³

The finding aid states that Mason ceased communicating with Manson by the late 1980s but continued to hold him in high esteem, a position that angered more conservative figures in the white power movement.¹ ProPublica reported that Mason also struck up a friendship with Manson, who became another hero for Atomwaffen.⁹ Alan Prendergast described Mason in Westword in 1995 as a 44-year-old white supremacist with ties to several American Nazi organizations and a longtime pen pal of Manson, and wrote that the Siege newsletter was the voice of the Universal Order he had founded, inspired by his extensive correspondence with Manson and other members of the Manson Family.⁴

A 2022 government sentencing memorandum in the prosecution of AWD leader Kaleb Cole states that the "Death to Pigs" image used in Atomwaffen propaganda was lifted from a crime-scene photograph taken at one of the Manson murders.¹⁰

Colorado and Ohio Convictions

Prendergast reported in Westword in September 1995 that sheriff's deputies raided Mason's rural home in southern Ohio in 1988 and 1991 and seized photographs of a fifteen-year-old girl, that Mason pleaded guilty to two misdemeanor counts of "illegal use of a minor in nudity-oriented material," and that he received a $500 fine and a suspended sentence before leaving the state. The same article states that police in Ohio reportedly contacted the Colorado Bureau of Investigation about Mason shortly after he arrived in Las Animas, Colorado, a town of 2,500 in Bent County, Colorado, in 1992, and that he had served time in his youth for a racially motivated assault.⁴ The Kansas finding aid dates the move to Colorado to 1993.¹

According to the same article, Las Animas police arrested Mason on March 30, 1994 and charged him with two counts of sexual exploitation of a child and two counts of contributing to the delinquency of a minor. Investigators removed hundreds of pounds of material from his house, most of it horror videos, Nazi and Manson literature and adult erotica. Mason was released on bond in May 1994 and about three weeks later was back in jail on a charge of felony menacing after a confrontation in which, according to the other persons involved, he had a handgun; Mason said he never drew it. The district attorney's office dropped the exploitation charges in return for a guilty plea to the menacing charge, and Mason was sentenced to three years in prison in the spring of 1995. He had faced up to 32 years on the exploitation charges. Prendergast interviewed him at the Arrowhead minimum-security prison near Canon City, where Mason said: "Anybody aspiring to a revolutionary position has got to expect to be in prison sooner or later."⁴ Westword reported in 2020 that he took a plea deal on the menacing charge and received a three-year sentence.¹¹

The SPLC profile records the same sequence: the Ohio raids in 1988 and 1991, a 1992 plea, and in May 1994, after release on bond, a threat with a firearm against two people that led to an arrest for felony menacing. It says the exploitation charges were later dropped, that Mason began a three-year sentence in May 1995, and that he was released in August 1999.⁵ Der Spiegel reported that after he was charged with child abuse, police searching his apartment found naked photographs of a 15-year-old girl, along with swastika flags and images of Hitler and Joseph Goebbels.¹² The Counter Extremism Project describes the Colorado charges as stemming from a relationship with a 14-year-old girl in Ohio, and says Mason was imprisoned for three years and then again for parole violations.³

Iron March and Atomwaffen Division

For roughly two decades Siege remained a marginal text within the far right.⁵ Members of the Iron March forum discovered Siege in 2015 and began promoting it.³ Der Spiegel reported that Atomwaffen Division was founded on the forum that year and that the group made Mason its ideological authority.¹² Brandon Russell announced the group on Iron March in October 2015. AWD's activities, aesthetics and strategic orientation drew on Mason's writings.⁵ AWD adopted Siege as required reading for its members, and ProPublica reported that the book serves as the backbone of the organization's ideology, worldview and training program.⁶ FRONTLINE and ProPublica broadcast an investigation of the group on November 20, 2018, produced by Richard Rowley, A.C. Thompson and Karim Hajj, describing its recruiting inside the U.S. military.¹³

ProPublica reported in 2018 that the group's leader, John Cameron Denton, shaped its ideology and selected the books that new recruits must study.⁶ Der Spiegel reported that Denton claims to own the rights to Mason's books, and that members tracked Mason down in 2017 after years of searching. Denton is quoted in the same report as saying "James Mason passed the torch on to us."¹² Westword reported that Samuel Woodward visited Mason in Denver in late 2017.¹¹ ProPublica reported that Jeffrey Kaplan, who interviewed Mason in the 1990s, described him as "a true believer."⁶

Der Spiegel lists the May 2017 killings of two housemates in Tampa by Devon Arthurs, a member who had converted to Islam, the December 2017 killings in Reston, Virginia by a 17-year-old AWD-linked member who admired Mason, and the January 2018 killing of a college student in California by Woodward.¹² The ICCT study states that AWD members were implicated in or convicted of five murders.² The government's memorandum in the Russell case records that Arthurs told police the group was "started and led by Russell," and that Russell had materials in the house to kill civilians.¹⁴ Russell pleaded guilty on September 27, 2017, and was sentenced to five years.¹²¹⁵

The 2019 Las Vegas Gathering

In October 2019 Vice reported on a propaganda video posted to a new dark web site, in which Mason and an AWD member declared that the organization needed to act before law enforcement shut it down. Vice described Mason as a 67-year-old neo-Nazi who had been in the movement since George Lincoln Rockwell, and as the author of works advocating lone-wolf violence by white supremacists.¹⁶

Ali Winston wrote in Rolling Stone that Joshua Caleb Sutter of Tempel ov Blood, an Federal Bureau of Investigation informant, attended AWD's 2019 2019 AWD Nuclear Congress in a Las Vegas hotel room with several high-ranking members and Mason, who "urged the creation of a new fascist regime through murder, small 'lone wolf' terror attacks, and relentless war against the government."¹⁷ It was his first documented in-person appearance with the organization.¹⁷ The government's memorandum in the Cole case states that AWD hosted a "Death Valley Hate Camp" in Las Vegas on January 25, 2018.¹⁸

Canada, Australia and the 2020 Disbanding

On February 3, 2021 the government of Canada listed Atomwaffen Division, The Base, the Proud Boys and the Russian Imperial Movement among 13 new terrorist entities, four of them ideologically motivated violent extremist groups.¹⁹ On June 25, 2021 the government listed Mason, describing him as "one American neo-Nazi who has provided ideological and tactical instruction on how to operate a terrorist group," and as the second individual added to the Criminal Code list.²⁰ The Counter Extremism Project reads the listing as concerning instruction given to AWD.³ The United Kingdom proscribed Sonnenkrieg Division by an order made on February 27, 2020, and proscribed Atomwaffen Division, including National Socialist Order, by an order in force from April 23, 2021.²¹²² On February 17, 2022 Australia added the National Socialist Order, which the Associated Press described as formerly known as Atomwaffen Division, to its list of terrorist organisations.²³²⁴

On March 9, 2020 an audio recording attributed to Mason announced that AWD would disband immediately. Vice confirmed the recording's authenticity with several sources familiar with Mason's voice.³ Westword reported that members approached Mason that day and asked him to announce the dissolution. Mason said: "Officially, as an organization, no more."¹¹ Joanna Mendelson, a senior investigative researcher at the Anti-Defamation League's Center on Extremism, told Westword that the announcement was "the ultimate protective clause," and that it did not end the group's messaging.¹¹

On February 26, 2020 federal authorities arrested John Cameron Denton in Montgomery, Texas for his alleged role in a swatting conspiracy; the United States Attorney's Office for the Eastern District of Virginia described him as a former leader of Atomwaffen Division in Texas.²⁵ Four other AWD members were arrested the same month for sending threats to journalists.³ Denton pleaded guilty on July 14, 2020 and was sentenced on May 4, 2021 to 41 months in prison.²⁶ On September 29, 2021 a federal jury in Seattle convicted Kaleb Cole of conspiracy, mailing threatening communications and interfering with a federally protected activity; the Department of Justice release noted that one poster carried the words "Death to Pigs," the message Manson followers wrote in blood at a home-invasion murder.²⁷ On November 8, 2021 a self-described group of former members announced an AWD revival online. On November 12 the American Futurist released a video of Mason calling the new group a "stupid action on the part of one lone nut."³ On October 30, 2022 the American Futurist site, which had published Mason's material, announced it would sever ties with him while continuing to sell Siege.³

Documented Citations

A 2018 study by the Counter Extremism Project of the book's influence identified, in the figures Johnson and Feldman later quoted, 33 extremist entities (21 individuals and 12 organizations) with ties to the book, and of the 21 individuals, nine "have been involved in acts of violence, four have been involved in specific murders, and four have been involved in threats or acts of terrorism."⁸ The Counter Extremism Project's own version of the study counted 32 entities (21 individuals and 11 organizations) in 2019, and its current version counts 41 (26 individuals and 15 organizations), of whom nine individuals have been involved in violence, four in specific murders and five in threats or acts of terrorism.²⁸ The ICCT study, which describes "a recently-revived doctrine advanced by the neo-Nazi ideologue, James Mason, now termed 'Siege Culture,'" states that AWD members have been implicated in or convicted of violent crimes "including five murders."²

Europol's report on 2021 stated that "SIEGE and Accelerationism, both with significant potential for inciting violence, were the most prominent ideologies in 2021, especially attracting young people radicalised online."²⁹ Its report on 2020 described SIEGE as the manifesto for groups such as Atomwaffen Division, Sonnenkrieg Division and the Feuerkrieg Division, and as a 563-page collection of newsletters produced by Mason during the 1980s.³⁰

In May 2026 the Anti-Defamation League reported that the manifestos of Cain Clark and Caleb Vazquez, the two attackers at the 2026 Islamic Center of San Diego Shooting, named William Pierce's The Turner Diaries and Mason's Siege as works that "should be read almost biblically by all soldiers of the white race."³¹
