Siege is a book collecting the articles of American neo-Nazi James Mason, former leader of the National Socialist Liberation Front and Universal Order. It collects the text of Mason's SIEGE newsletter (1980-1986) and other propaganda, arranging it according to topic. It places an emphasis on gaining power through armed struggle rather than political means.
It was first published by Storm Books in 1992, edited and introduced by Michael Moynihan. It was republished, with a new preface by Mason and an introduction by Ryan Schuster, in 2003
