Grimm Reaper said:A few facts:
The territory Hitler occupied at his peak went far beyond the size of Spain.
Hitler was easily capable of an occupation of all of France, as he did for more than 18 months after the Allies landed in French North Africa.
In Spain Hitler would have had a special advantage. Considering attitudes in Spain in our OTL, and how the increasingly Stalinist Republicans would have behaved, it is safe to say that something like 90% of the population either welcomes the Nazi liberators or at least sees Franco as no worse.
Once the Germans go through the Spanish gulag they have a domestic occupation force needing only a few weeks of rest and proper food and medical care. And some of the armaments captured from the Republican regime.
Now we have the Luftwaffe and wolf packs stationed minutes from Gibralter and the lifeline to Malta.
Does this even change much elsewhere? All that probably happens is that the Battle of Britain is reduced or cancelled and by January of 1941 the British position is even worse. This, of course, does not consider the chance that much of the British army and air force weren't destroyed trying to hold the last ally on the continent.
As for the effects on Greece standing up to Hitler's junior partner or a certain coup in Yugoslavia going off on schedule...
Im still not convinced. We're all forgetting an important factor here. Time. Its all very well to say Hitler would invade Spain, but we've also got to consider how long it would take. And you've still got to consider troop numbers. The troops would have to come from somewhere, most likely France. Its a pretty much fixed number of troops, it not like they grow the bigger he expands. Even if they get some spanish volunteers, they are going to suffer casulities, and there will be some sort of occupational resistance. Also, with less troops in france, does that mean a stronger resistance movement there?
And the bit about Spanish citizens rising up to welcom the Nazis is unlikely, and for several reasons. One is the fact that northern spain was never occupied by the Nationalist forces in the OT, and No-where near in my timeline. You talking Basque and Catalan, which are not going to take an occupation, by any forces lightly. Also, what makes you think the Spanish are going to support German occupation? first of all, i imagine that most pro-nationalist sympathisers would have been rounded up and dealt with, much the same way that Rebuplicans were in the OT. If the allies had invaded in the OT, they wouldnt have had a supportive populance. Think about it.
