Martens writes primarily in French, but his books, especially "Another View of Stalin", have been translated into Dutch, English and numerous other languages. In "Another View of Stalin", Martens regards as the main factor behind the Ukrainian famine to be bad conditions and alleged class enemies. With regard to Aleksandr Solzhenitsyn's novel "Gulag Archipelago", Martens stated: "This man became the official voice for the five per cent of Tsarists, bourgeois, speculators, kulaks, pimps, maffiosi and Vlasovites, all justifiably repressed by the socialist state."
