Raimond J. Sontag judges this book as a good historical study of the negative period, the different personalities of the dictators and how their background influenced the developing their future agendas (Mussolini was a journalist and Hitler was an abnormal adolescent).
Before the war Mussolini started a campaign of Italianization through all the regions close the boundaries eventually changing his political view after Hitler came to power.
During the war and the following the armistice of Italy it became clear that the territories occupied by the Nazis (especially in the northern borders) discovered a renewed anti-Italian sentiment declaring de facto a complete deprivation of power of Mussolini.
