I'm sorry, but are we talking about the same Italian army that took years to go from mindstaggeringly incompetent to merely rather so?
No, the italian army that had fought for years in one of the most horrible and difficult terrain for any attacker that existed in Europe under one of the harshest discipline possible and with minimal support from his allies.
Which is why the great powers would be trying to break up the fight rather than saying fuck it lighting the fuse with a road flare.
Maybe yes, maybe not; looking at the various series of war scare it was only a matter of time before a general war erupted and this situation had become a little too widespread to keep easily contained.
Yes and as history has made very clear Conrad never gets what he wants, the other Great Powers (especially Germany) will be trying to get peace talks underway, so a Tsushima-esque naval engagement is the most that would realistically happen.
.
A-H had given Italy an ultimatum that she as not respected...this mean that old Conrad had much more leverage for a short victorious war than OTL and any Tsushima-esque naval engagement will be averted, the shallow water of the Adriatic are not the best place for this kind of engagement.
The German being more communicative will have not changed a lot; the war demonstrated that Conrad is not a good listener. I never said that was impotent, just that was not the well oil murder machine that Boonz make of it, it was underfunded and ill managed, plus more suited for short time operation than for longer war with big loss and OTL needed a lot of German help to continue to be operative.
Potiorek action will be against War Plan R but clearly demonstrate an almost criminal understimation of the enemy (or overstimation of your own) and with the general opinion that Conrad (and much of the A-H) enstablishment had of the italians in general...the recipe for a disaster are all in position.
