Italy is a Soft Underbelly in Europe and They have done little Success in the First World War at the Battle of Isonzo River. They Sustained Heavy Casualties and Bad Leadership and in the Second World War, they Failed to Invade France thru the Alps.
The Italian's only have to Rely on Germany because they have better Leadership and Well Trained Army than Italy.

The Allied Powers are Better Equipped and Better Trained than Italy and Germany. They may sustain Heavy Casualties but they are a force to be Reckoned with even in Odd Numbers.
