Hm I think you are Serbian ? Am I right? The name of the country was Socialist Federal Republic ( means Federation of 6 Republics,6 Nations ) you can read the constitution od SFRJ, it was Socialist Federation ,with Social Democrat establishment free Economy ,non of the companies were property of the government, so its not even close to a Communist country.Do you understand the word Federation? six countries in one Federation,six nations in Federal Union, every single Republic had its own president prime minister and parliament. European Union is very good example for you, dont tell me that Germany France Italy Spain and other countries are  only sovereign states of Communist Europe ?
