Early in the 1930s he contributed to a series of radical nationalist magazines while also serving as editor of the fiercely anti-German daily "Le rempart" in 1933 and as editor of Paul Lévy's anti-Nazi polemical weekly "Aux écoutes". In 1936 and 1937 he also contributed to the far right monthly "Combat" and to the nationalist-syndicalist daily "L'Insurgé", which eventually ceased publication – largely as a result of Blanchot's intervention – because of the anti-semitism of some of its contributors. There is no dispute that Blanchot was nevertheless the author of a series of violently polemical articles attacking the government of the day and its confidence in the politics of the League of Nations, and warned persistently against the threat to peace in Europe posed by Nazi Germany.
