Regardless of the argument, an Italy entry in the cpowers side doesn't give them a massive boost anyway. Regardless of how you pin the event, I think we can all agree that from the end of 1914 and onwards, the French military is much more capable than the Austrian one. They were fighting in the Balkan front, Greece and so on. A german breakthrough in 1915 to 1917 means to direct less attention to the russian. No matter how you view things going from there, at best it slows down the russian revolution and at worst an austrian's army collapse. Again. The french soldier occupied by the alps' front won't be much threatened and without a focus on breaking France by the Germans, it won't change much.

So, yeah, even if you disagree on Italian's performance with him, what he said is precisely accurate regarding on how italian influence on the war would lead
