Unlike some other extremist organizations, the National Socialist Movement (NSM) actively works with other white supremacist groups ranging from racist skinheads to the Klan to White Revolution.

The “About the National Socialist Movement” section of the NSM Website states, “We cooperate and work with many like minded white nationalist groups such as the KKK (Ku Klux Klan), Aryan Skinheads, the Racial Nationalist Party of America and many others which are either neo Nazi or at least, racially aware of our Aryan Heritage.”

NSM members also attended the “National Alliance 2007 International Holocaust Revisionist Conference” at the National Alliance property in Hillsboro, West Virginia. Speakers at the event included Willis Carto, anti-Semitic propagandist and publisher of American Free Press and The Barnes Review, a Holocaust denial publication; Arthur Butz, Holocaust denier and associate professor of electrical engineering at Northwestern University; and Edward Fields, white supremacist and publisher of the extremist magazine The Truth At Last.

Speakers at an April 2006 event in Lansing, Michigan included Klan members and white supremacist Internet radio host, Hal Turner. Also in attendance was veteran white supremacist Tom Metzger. Two months later, a joint Klan and NSM event occurred at the Antietam Battlefield in Sharpsburg, Virginia.

At a June 2005 rally in Yorktown, Virginia, the NSM teamed up with the American Thule Society, a white supremacist group, in an event to “Honor our brave American forefathers.” Speakers included representatives from both groups. The NSM reported that the event was attended by members from various white supremacist groups including the Old Glory Skins, Aryan Nations, KKK, Creators, Teutonic Knights, and American Front. After the rally, KKK Imperial Wizard Virgil Griffin's organization, Cleveland Knights of the Ku Klux Klan, emailed Jeff Schoep to let him know that the Klan members that had been sent to the rally in support of the NSM had been turned away by police.
