The conclusion cautions against dismissing Italy because of its uneven wartime performance. Italian forces occupied a strategically powerful position, and the Regia Marina was the strongest and most balanced European Axis fleet. Its presence historically forced opponents to guard several theaters even when Italian forces were not actively attacking. Once that threat disappears, French troops reinforce the north, British sea power concentrates against Germany, and a much larger reserve becomes available for the Pacific. If Greece later joins the Allies for another reason, its position could also open a southern route for attacks on German oil supplies.

Why neutral Italy changes the whole war
Italy's armed forces and geography forced the Allies to disperse resources; removing that pressure strengthens France, Britain, Norway, and the Far East at the same time.
