Operations of Intelligence Agencies in the Socialist Federal Republic of Yugoslavia

Rad se bavi prikazom djelovanja obavještajno – sigurnosnih službi Socijalističke Federativne Republike Jugoslavije s naglaskom na rad, metode i sredstva kojima se su se koristile Odjeljenje za zaštitu naroda i Služba državne bezbednosti, tzv. OZNA i UDBA. U početku rada prikazan je ustroj Jugoslavije i promjene ustava koje su utjecale na sigurnosno – obavještajni sustav SFRJ. U glavnom dijelu detaljnije je objašnjeno funkcioniranje OZNA – e i UDBA – e te metode koje su koristili u borbi protiv disidenata. Osim unutarnjih neprijatelja, službe su imale posla i s jugoslavenskom emigracijom koja je bila raširena po čitavom svijetu. Mnogi su završili svoj život nakon ispaljenog metka nekog od doušnika ili agenata UDBA –e, a jedan od njih bio je i Stjepan Đureković. Njega su ubili Josip Perković i Zdravko Mustač osuđeni na doživotni zatvor, a navedeni slučaj unio je puno prijepora i konflikata na relaciji Hrvatska – Europska unija – Njemačka.This essay deals with the presentation of the activities of the intelligence and security services of the Socialist Federal Republic of Yugoslavia, focusing on the work, methods and means used by the National Protection Unit and the State Security Service, OZNA and UDBA.
