What I was trying to do was inject another "What-if" into this uber-scenario.
I understand that and, as I've written, your attempts have been well meaning. Sadly, What Ifs on the level of those you've proposed in all good intention run contrary to the "tone" of the time line as set forth by it's creator.
CalBear has allowed himself only one miracle, the lack of Nazi nuclear weapons and even a program to produce them. Everything else has been hard headed reality. Allowing Italy or any of the other Nazi "allies" a consequence-free escape hatch of sorts is too much of a miracle.
I also believe we need to look at the damage an Italy which remains "loyal" to Germany until Germany's actual defeat or until hours before Germany's actual defeat will suffer because the desire to grant Italy an escape hatch is based in part on limiting damage to Italy.
The Allies did invade Sicily, did conduct a False Peak operation on the Italian peninsular, and have bombed Italy regularly but Italy is not suffering the devastation France is suffering around the invasion sites, the devastation France, Holland, Belgium, and Luxembourg will suffer as the Allies advance to Germany, and the devastation that Germany will suffer once the Allies finish their business there.
It seems perverse but, given the Allies' focus on Germany, a focus which drove the choice of landing site and subsequent advance into Germany, Italy runs the risk of greater damage by joining the Allies than it does by remaining "loyal" to Germany. An Italy which surrenders hours before or even slightly after Germany "only" faces Allied occupation and reconstruction while an Italy which surrenders too soon faces megadeaths at the hands of it's late master.
As I wrote earlier, if Mussolini and the rest of his government are truly heroic they'll choose a potential Allied noose with their names on it in order to prevent the certain deaths of hundreds of thousands, if not millions, of their fellow Italians.
And a happy one to you also. I hope your holiday was as convivial as mine.Happy Thanksgiving!
