Reddit reviews Fascism Past and Present, West and East: An International Debate on Concepts and Cases in the Comparative Study of the Extreme Right (Volume 35) (English and German Edition)

The "literal definition" from Wikipedia?

By that definition, not only Nazi Germany and Fascist Italy were fascist, but a number of non-democratic regimes of the 20th century would have to be classified as fascist. While the Krelim's current rhetoric is imperialistic, bellicose and nationalistic, this is still far from amounting to an ideology of revolutionary ultra-nationalism, which is the most consensual definition of facism available in international comparative fascist studies today (if you're interested, I can recommend this one). If Putin's administration is fascist, how should one label all those Russian right-wing extremists who complain that its policies are too liberal and pro-Western?

For example, ideologies of national rebirth, which are very common in fascist countries, were present in Fascist Italy and Nazi Germany, but an official and openly proclaimed ultra-nationalist ideology of national rebirth which resembles the grandiose fantasies about an imminent restoration of national greatness is lacking in Russia.

Nationalistic, militaristic and authoritarian leaders existed long before fascism was introduced to the world. Those traits may share some common ground with fascism, but to call someone fascist based just on that is plain wrong. Maybe when he begins introducing corporatism, banning labour unions and imprisoning the entire communist party will it become reasonable to call him fascist.
