Contemporary Cuban thought counts among its ideological pillars the critical work of Armando Hart, supported by Marti's ethical roots of Cuban revolutionary politics and culture, which were put into practice by the centennial youth led by Fidel, and where Hart integrated body and soul from the July 26 movement, to fight against the repression of the tyrant who bloodied the homeland. With the revolutionary triumph of January 1, 1959, he fulfilled with exemplary devotion the task entrusted by Fidel to achieve in a short time the general education of the people and later, to direct the cultural policy of the Revolution from the socialist power under construction, a task that he had as a unitary premise, develop the Cuban revolutionary ethic from education and culture, to face and overcome the challenges posed by the enemy of the Cuban nation, Yankee imperialism. The objective of these reflections is focused on encouraging the university debate on ideological warfare in digital networks from Hart's revolutionary thought; war that the empire leads in the 21st century mainly against the Cuban youth, in order to undermine the unity of the people from within and defeat the Cuban Revolution. The study is a synthetic summary of a set of ideas linked to the issue of ideological combat in the networks, as a result of the bibliographic review, analysis and synthesis of concepts addressed by Hart in his work.
