What is the importance of WWII in the nonfiction book, War in Val D'Orcia, 1943-1944?

WWII, fought in the years 1939 and 1945, engaged the military forces of the entire international community ranged, for the most part, in one of two camps, the so-called Allies and Axis (see below). The conflicts in the narrative can be seen as a micro-cosmic manifestation of the larger conflict - in other words, the conflict between life-preserving humanism and life-destroying dictatorship.
