The Polish Operation of the NKVD served as a model for a series of similar NKVD secret decrees targeting a number of the Soviet Union's diaspora nationalities: the Finnish, Latvian, Estonian, Romanian, Greek, and Chinese. Of the operations against national minorities, it was the largest one, second only to the "Kulak Operation" in terms of the number of victims. According to Timothy Snyder, ethnic Poles constituted the largest group of victims in the Great Terror, comprising less than 0.5% of the country's population but comprising 12.5% of those executed. Timothy Snyder attributes 300,000 deaths during the Great Purge to "national terror" including ethnic minorities and Ukrainian Kulaks who survived the early 1930s.
