Churchill, Chamberlain, and Norwegian trust

Are the Scandinavian diplomatic archives fully open, and would Norway have trusted Churchill more than Chamberlain?

The archives are not fully open, but Churchill's established reputation for forceful action gave Norwegian leaders reasons to view him differently from Chamberlain.

The exchange asks whether the diplomatic record is fully open and whether Norwegian leaders would have treated a promise from Churchill differently from one made by Chamberlain. The relevant Scandinavian correspondence is not fully declassified, so the record remains incomplete. Churchill nevertheless carried a distinct reputation from the First World War and interwar period as a forceful, persistent political figure. That reputation did not guarantee success, but it could affect how Norwegian leaders judged British resolve after the failed guarantee to Poland.
