The Russians normally don’t care what foreigners watch on the telly, but the Kremlin has taken grave exception to a box set drama from Norway named Occupied. Its premise: Arab civil wars shut down oil exports and Norwegians elect a Green government to close down North Sea oil as well. Panic ensues, and Russians invade Oslo – not with tanks, but with a cell of masked men in unmarked uniforms who make the Prime Minister an offer he can’t refuse. He accepts “assistance” from Russia, while he pumps out the oil they want. And the European Union? It meekly backs the Kremlin.

It’s clear why the real-life Russians are so angry: all this is far too close to the bone. The Scandinavians have been feeling the chill from Moscow for a while now. Vladimir Putin has been testing their defences, sending fighters into their airspace and watching the reaction. He annexed Crimea by soldiers in unmarked uniforms and having a pliable politician ask for Russian help. No wonder the Baltic states are anxious, or that previously-neutral Swedes and Finns are suddenly talking about joining Nato. The Russian bear is on the prowl.
