What is a 'drone wall'? Europe backs response to Russia amid Ukraine war

Europe’s leaders gathered at summits in Denmark to respond to Vladimir Putin after a wave of drone incursions above airports and sensitive sites.

LONDON — Something is shifting in the skies of Denmark.

Europe’s leaders met in Copenhagen this week with security fears pressing in from every direction and a new determination to face down what they say is a mounting threat from the Kremlin.

Fortified by intense security measures after a wave of drone incursions above airports and sensitive sites, two high-stakes summits in the Danish capital offered a mounting sense of collective clarity — and a possible solution that sounds like science fiction: a “drone wall.”

“There is only one country that are willing to threaten us, and it is Russia,” Danish President Mette Frederiksen told reporters on Wednesday, adding that Europe was in the middle of a “hybrid war.”

“I think we are in the most difficult and dangerous situation since the end of the Second World War,” she added. “I want us to rearm. I want us to buy more capabilities. I want us to innovate more.”
