But not in the US, at least not yet: Lara Jakes, Drones, Exploding Parcels and Sabotage: How Hybrid Tactics Target the West, NYTimes, Jan 4, 2025.
In recent weeks, reports of drone swarms over the United States’ East Coast have brought fears of hybrid warfare to widespread attention. Only 100 out of 5,000 drone sightings there required further examination, U.S. officials said, and so far none are believed to have been foreign surveillance drones. But it is a different story for the drones spotted in late November and early December over military bases in England and Germany where American forces are stationed.
Military analysts have concluded those drones may have been on a state-sponsored surveillance mission, according to one U.S. official familiar with the incidents, who spoke on the condition of anonymity to discuss an open investigation. British and German defense officials declined to discuss details of the sightings.
Experts said the drones’ presence was indicative of a so-called hybrid or “gray zone” attack against the West, where a range of tactics — military, cyber, economic and even psychological — are used to covertly attack or destabilize an enemy.
As Russia, Iran and other hostile states become increasingly brazen in their hybrid attacks on Western countries — such as the hacking of sensitive computer systems and alleged assassination plots — defense officials face a thorny challenge. How to deter such acts without touching off a broader and potentially deadly conflict? And how to assign blame against the attacker when the strikes are designed to evade culpability?
