Breh thats not the reason they lost. The war. It was because of over expansion and fighting on multiple fronts. They were literally fighting and occupying in eastern europe, fighting and occupying in western europe and fighting in northern african all at the same time. They were stretching their military too thin just like japan. The main reason was because they didn't have the resources that larger countries like russia and america. So they had to occupy and attack other countries to gain resouces. Thats why every country the occupied they literally bleed them of their resources to fund their war effort.
Which basically meant when they ran out of military resources and were stretched to thin the walls came closing in.
