The intrusion of a significant number of Russian drones over Poland last week was already focusing minds in Nato, not least on the thorny question of where it draws its “red lines”, when another such incursion took place at the weekend.
Last Wednesday, 19 Russian drones were found to have crossed over into Polish airspace, some having travelled hundreds of miles inland, before a handful were shot down by local and Nato aircraft. It marked an unsettling escalation of tensions between Russia and Europe, and prompted Poland’s prime minister to declare military conflict on the continent “closer than at any time since the Second World War”.
