On the morning of September 10, Nato jets were scrambled over eastern Poland to defend the airspace of an alliance member against an incursion by Russian drones. It was the first time that the west fired shots in the Kremlin’s war against Ukraine.
This incursion marks a serious escalation by Moscow. But it also highlights yet again that the west has no clear red lines and is unprepared to respond decisively if red lines that were taken for granted in the past – like the territorial integrity of Nato members – are crossed.
This latest Russian escalation isn’t the usual war of words. It was only last week that Russia’s president, Vladimir Putin, warned that foreign troops in Ukraine would be legitimate targets for his invasion force.
