Again, an awesome update from Macragge!
Don't forget that France is a large country, while the northeast will be in a poor condition, the western seaboard will be fine and likely almost unscathed in places.
The loss of Paris will be a huge problem as I have said before, since it might that command and control will be problematic for a while. But if most prefects have survived on a local level (and they likely have in most départements), I can easily see them being granted emergency powers in order to get things up and running.
I dunno...while I agree that some of France might escape in relatively good condition, you have to remember that the French retained their own considerable nuclear capability, and at the time of the war would've had several nuclear bomber, submarine and missile bases that would surely have been hit, if nothing else;
- Luxueil Air Base, in Franche-Comte (French/Swiss border for those who don't know);
- Istres-Le Tube AB, near Marseille;
- Toulon AB, (nuke storage);
- Tours would get it, as it has a nuke component production site;
- The Centre de Etude de Valduc in Burgundy (nuke production & assembly);
- CESTA, nuclear weapons R&D, in Aquitaine;
- Brest, having a nuclear sub base, would be a big target;
- The French IRBM silos in Vaucluse (SE France) would doubtless get hammered;
- Landivisiau Naval AB in Brittany (land station for nuke-armed Navy planes).
Anyone - feel free to correct me if I got those sites wrong or if I'm otherwise full of it.
That said, even those targets do leave large areas intact (if irradiated), if Paris were the only city to be targeted as such. So...better than the UK, but not exactly "unscathed". Methinks this TL is a bit kinder to France than it'd have been if I wrote it.
