Opinion | Suspicious Drones Over Europe

Has the West absorbed the right lessons from Ukraine’s war with Russia? For the unsettling answer, look at what’s buzzing mysteriously in the skies above Europe’s cities. Drones were spotted this month in France, loitering around a gunpowder plant and a train station where tanks are located. Others were seen recently near a Belgian military base, a port, and a nuclear power plant.

Belgium’s defense minister told the press the drones near military bases were “definitely for spying.” The provenance of other suspicious drones is less clear. Yet whatever their source, they’re a security threat. The Netherlands suspended flights in Eindhoven Saturday after a drone sighting, and similar episodes have unfolded this month at airports in Sweden, Germany, Belgium and Denmark.
