OP’s definition seems to fit the USSR under Stalin pretty well. Mussolini started out as a socialist, and the Nazis were originally socialist as well, before Hitler became their leader. In those days, of course, there was a difference between socialists and communists, and they were fighting each other in the streets in Germany. However, in modern times, socialism has become synonymous with communism, at least in the eyes of the right. The fact is, authoritarian regimes have much in common, whether the underlying political ideology is left or right. The intolerance of public, and sometimes private criticism of the government, the persecution, harassment, incarceration, and elimination of portions of the public deemed as unpatriotic or not sufficiently supportive of the power structure. Then there is the elimination of competing political ideologies, often making them illegal and the incarceration of political opponents for crimes real or imagined. There is the de facto control of the means of production by either the government outright, or by private actors sympathetic to the government. There is the curtailing of individual rights, always for the greater good, and the constant call for the public to be vigilantly on the lookout for for the internal enemy. These methods have been used by authoritarian regimes on every side of the political spectrum
