The author goes back to the beliefs and philosophy of Augusto César Sandino for an interpretation of the ideology of the Sandinista regime. He concludes that the FSLN's leaders are neither social democrats nor traditional Marxist-Leninists but, rather, exemplars of a Marxist-Leninist New Left influenced by Sandino's anarchist version of communism, for which an atypical theology of liberation, expounded by Father Ernesto Cardenal, is "the single most important carrier." A very interesting and thoughtful study.
