Winston Churchill had said about World War II that it was a war that should not have happened. This book was written with the ambition to help prevent another such war from happening again. To prevent humanity from returning to a similar state of madness.
World War II was the most insane and tragic adventure of human life. Never before has so much intelligence, political, military, and scientific, so much bravery and such a quantity of human and material resources been used to "write" this Epic of Destruction. "The passion for interest became a disaster." A disaster that extends to our own time through various paths and in various ways. To stop this extension, fragmented knowledge is not enough, but a complete understanding of the events is necessary. That is why we present the facts ab ovo and ad finem. From the beginning to the end and across the entire extent of the planet. However, in this book, it is not the fact that is abundant, but the reflection, the highlighting of causes, motives, and consequences. The author, a child of that great war, excludes heroism but does not idealize it. With this book, although it is a book of war, he highlights the heroism of peace. It does not provide stimuli or pretexts for new wars.

(Volume I concerns the situations and events that led to the war until the Battle of El Alamein (1943). Volume II concerns the Battle of Greece. Volume III concerns the war in Russia. Volume IV concerns the invasion of Sicily-Italy, the invasion of Normandy, and the collapse of the fascist and Hitlerian regimes. In an epilogue, the political and diplomatic events are examined.)
