The sheer volume of headlines tells its own tale. Russian drones over Poland and Romania. Russian fighter jets in Estonian airspace. Russian aircraft buzzing a German naval frigate in the Baltic Sea. Unidentified drones over Copenhagen and Oslo airports. Most recently, in the early hours of Thursday, further drones appearing at other Danish airports.
In just over a fortnight, European states have reported a striking spate of incursions into their airspace. Russia has repeatedly denied responsibility and questions remain over individual events: so far, Denmark has said only that a “professional actor” was at work in the airport incidents and that it can’t rule out Russia. But overall, there is a pattern which fits clearly into Moscow’s longer record of provocations and often implausible deniability – and which amounts to a notable escalation.
