The book "Security Systems of Totalitarian and Authoritarian States" by Vladimir Vujanic offers a comprehensive analysis of the security policy structures in totalitarian and authoritarian governments. It highlights the role of the security apparatus as a central element of these forms of governance and examines how this apparatus serves the interests of the national leader. The work discusses historical examples such as Nazism, Fascism, and Stalinism, drawing parallels to contemporary systems like North Korea and Cuba. By exploring the functioning of intelligence services and political police, it becomes clear how these institutions are used to suppress opposition and control the population. The book is aimed at readers interested in political science, history, and the dynamics of power and control.
