“Ethnic cleansing” is a term coined by the genocide perpetrators during the wars that led to the dissolution of Yugoslavia. The term derives from military terminology referring to the “cleaning” (čišćenje) of an area after a military operation. Propagandists added “ethnic”, creating the term “etničko čišćenje”, and the media, politicians, even academia and international organisations helped spread it and keep it alive.
i was very surprised that this term is new and yet became widely used. In my own view it is so transparent in implying that some ethnicities are "unclean" that it should obviously not be used. Call it genocide, don't use bad euphemisms.
