More! Have been watching this on UK television. Absolutely brilliant. The use of pseudo-operations by the Russians, their ability to illicit knee jerk reactions from the Norwegians that play into their overall strategy (the resistance/terrorists), soft power (in this case exemplofied by Russian patronage of a restaurent in more ways than one), the diplomatic machinations and the role of the media. Seriously good if slightly far fetched stuff. Also, the collaborationist narrative is fascinating given I don't recall if Quisling's name was ever mentioned. As for it being specifically interesting as an exploration of Russian "grey zone" strategies I think, if you read enough history, it applies to most powers (the US has done its own fair share of Grey Zone operations especially during the cold war for instance, as have British in olden times, and as are the Chinese in the East).
