i doubt that, it would also be an internal political disaster for germany.
german unification was a political process, and NL is more or less seen as kin.
i get the feeling you don't understand how deep certain things go.
and a repulsed attack would also mean that all the logistics that flow through the river rhine to germany would be gone, and that is a effin lot.
and you make the classic mistake by projecting 1940 mindset on the ww1 era, the 1930-40s germany mindset was the result of a period of national humiliation and economic depression and a bunch of crazies.
politcally the netherlands is always on the halfway point between germany and the uk.
simply because the british & french were no less unreliable. look at it from the 1916 perspective, at that point in time Germany has never tried to invade the netherlands or try to steal land.
the british stole scores of land from the netherlands (south-africa!) and wouldn't hesitate to do so again when given the chance, ditto for france (who started the majority of wars in the previous 500 yrs).
so the netherlands is always doing a balancing act between these, just to protect its colonies.
With the UK weaker and Germany stronger ITTL, surely it would make more sense for the Netherlands to 'pivot' closer to Berlin? After all, Germany has Finlandised Belgium (so no chance of Entente troops coming to the Netherland's rescue through there), and otherwise surrounds the country.
I don't deny that invading the Netherlands would come at a political cost for Germany- I can't see them doing it in the TL- but is it theoretically possible? Most definitely.
You are right with regards to Rhine logistics- that's something I'd not considered.
I notice you're Dutch whereas I am obviously not, so I'll back out and concede '
mea culpa' with regards to the politics- but I still maintain that a military invasion would be possible, even if it came at a political cost.
mobilisation strength around 4-500K
it was removed the schlieffen plan for a reason, and to attack NL you still need a casus belli,
and imperial germany is not nazi germany
500,000? Well, if Imperial Germany was able to fight million-man Entente armies for four years on the Western Front in OTL (to say nothing of the Eastern Front), then they should be able to beat half a million Dutch.
Since the PoD of this TL is in 1915, the Schlieffen Plan failed as OTL, and I don't deny that had the Germans included the Netherlands in their attack in autumn 1914 it would've gone poorly. However, I'm talking about an independent war against the Netherlands after TTL's WWI. And as I mentioned above, I can't see Germany doing this for political reasons- even a weakened UK would happily jump into the fight to keep the Low Countries neutral (which has been a keystone of British policy on the Continent for centuries).
However, all I am saying is that if in TTL's 1917, 1918, etc, an ASB makes the German
regime go batshit crazy and say "let's invade the Netherlands", they could pull it off. This won't happen because things just don't work that way, or as you said, 'i get the feeling you don't understand how deep certain things go.'
The only way a Dutch-German war could happen in
Place In the Sun is if it's part of a wider war involving the UK, France, etc, and I don't plan to replicate
Fall Gelb ITTL, thus making a Dutch-German war even less likely.
a further illustration
post WW1 belgium made the demands to annex the netherlands below the rhine (quite a thank you to NL for taking care of all those belgian refugees during the war).
during the war this plan was already going around, but was seen a german propaganda (which it turned out not to be). ultimately the plan caused quite a lot of outrage, and was shelved.
also during WW1 there were several attacks on dutch territory by entente aircraft, and then there is of course the infamous blockade by the entente of not only germany but also the Neutral netherlands.
in hindsight and the belgian behaviour, it is very possible that these entente attacks were meant to push NL into the german camp, so they could occupy dutch colonies.
it just illustrates the level of hubris among the entente .
and ittl the netherlands will probably more pro-german than otl (and otl there was a dislike for the entente post ww1.
Really? Belgium made that demand? Huh.
You aren't wrong with regards to the Netherlands being more pro-German, which brings me back to my original point: they're closer to a stronger Germany than a weaker Britain and France (which has treated them poorly.) The most likely thing as I see it would be the Netherlands ITTL adopting a neutral, albiet somewhat pro-German, foreign policy.
