Supposedly - if you study the files of the Kriegsmarine you'll find the true cause of Weserübung, and that being the desire for German bases in Norway. All other reasons for the invasion being subordinated this wish - and being mostly stuff used by Reader et al to "sell the idea to Hitler".
No I don't find it to be false - I find it to be HALF correct - as I've said beforeI take it as you find this interpretation of the cause(s) for Weserübung to be false...
Because when it comes to violating a nation's Neutrality for WHATEVER reason - it's about one side doing it and not the other, whoever that side may be. Neutrality is gone. One side doing it doesn't make it different from the other side doing it - no matter how welcome/friendly or not, it's still invasion and occupation. A transfer from Neutrality to being (on the same side as) one belligerent or the other.
For the Norwegians - no matter what they thought of the Royal Navy...the KM wanting bases or the RN wanting bases was the same thing; a change from Neutrality to Belligerency.
As I've said before on AHF - and quite frequently - "Neutrality" isn't a "third way"; "Neutral" politicians like Koht liked to think it was - but it isn't. What very few European and Scandanavian Neutrals survived, did so by keeping a foot in both camps to one extent or another, there was no "space" between the two belligerents to occupy.
How does this impact the "causes" for WESERUBUNG? Whether Raeder wanted Norway for his own bases, or to stop Britain having bases....Norway was to be invaded and occupied. Don't loose sight of this - a real war crime, a breach of the Hague Convention - in the "why" on Rader's part; only a month into the war he was proposing Hitler order the unprovoked invasion of a Neutral country.
HOWEVER - quite frankly, whatever's in the KM files, whatever Raeder's position was - the decision wasn't down to him. What we DO know from the history of events I outlined above is that the decision rested 100% with Hitler...and we have SEVERAL recorded occasions where he refused to move on Norway in line with Raeder's requests, and instead preferred to safeguard Norway's neutrality unless BRITAIN breached it.
Raeder may have made decisions for the KM - but Hitler made decisions for Raeder. And we KNOW what Hitler was thinking for October 1939-January 1940. Quisling recorded it, Halder recorded it, Keitel recorded it...
