I'm surprised France isn't more of an important player here anyway. They did have a fairly decent modern fleet OTL which their officers scuttled to keep the Nazis from getting it and gaining a fleet to challenge Britain. Churchill was terrified of this prospect. He even had the British hunt down some French battleships in their port in Algeria and open fire on the (still friendly) French ships, killing almost 1300 French naval personnel and sinking one of their battleships. THEY have historically been the preeminent land power of Europe, not Germany. With
Will the Belgians have completed their section of the defensive fortifications on the Maginot Line ITTL?
Also: it appears based on the timeline that Hitler chose to mess around in Norway rather than the Spanish Civil War. Does this mean the 2nd Spanish Republic survived? No Guernica? I may have missed whether or not Franco and his goons came to power there.
Italy is expanding their Mediterranean possessions, correct? They held Albania and Libya at this point OTL, iirc. Where else are they trying to expand? Hungary, Austria, Bulgaria, & Romania are part of the German sphere. Slovenia and Croatia? As Catholic areas along their borders in a weak state that makes some sense, particularly Dalmatia which had a significant Italian minority iirc. They would have a claim on Kosovo as part of Albania.
Not to worry, I will be getting to France after I get the Far East caught up! It's important enough that I want it to be the sole focus at that point without back-and-forth.
To address your other questions:
-Belguim- you'll have to wait and see, but 2 extra months isn't a lot of time
-Spain: Hitler did mess around in the Spanish Civil War, as in OTL. Norway started off much like OTL, but it started going really, really wrong for Hitler once the British intercepted the invasion force headed for Trondheim and Narvik. My apologies for not addressing it sooner. Spain remains officially neutral, as does Salazar's Portugal.
-Italy is indeed trying to rebuild their empire. TTL, they are building the 4
Littorio class battleships. They dispensed with modernizing the
Conte di Cavour and
Andrea Doria classes as they are so thoroughly outclassed now, instead building an additional 4
Trento class heavy cruisers and additional submarines. So far, they invaded Albania in early 1939 as OTL, and although France wasn't pleased, no action was taken for fear of driving Mussolini into a pact with Hitler; appeasement rearing its head again.
The counterbalance is that the Royal Navy has more ships to station in the Mediterranean. The TTL
Triumph class battleships are often on this station. As of 1940, Albania is the extent of their Balkan conquests. Libya is in Italian hands, although the Brits are keeping close watch; the situation is tense but tenable.
-Hungary under Horthy is officially an Axis-ally at this point; Romania and Bulgaria in all but a declaration
