With that in mind, some European officials have already poured cold water on the idea.

German Defense Minister Boris Pistorius voiced support for a “drone wall” concept but cautioned about setting realistic expectations at the recent Warsaw Security Forum.

“We have to think and act in priorities, and there are others,” Pistorius added. “Drone defense, of course, but not by a drone wall.”

That hesitancy is echoed by some analysts, who said the concept currently lacked clarity.

Retired Lt. Gen. Ben Hodges, former commander of the U.S. Army in Europe, expressed skepticism: “I’m not against it, but I don’t understand it.”

He elaborated to NBC News that many ideas lack connection to a larger, coherent plan. “Everybody’s got cool ideas,” Hodges said from the forum.

The Kremlin condemned the discussions, with spokesman Dmitry Peskov stating, “As history has shown, erecting walls is always a bad thing.”

Analysts nonetheless agreed on the urgency of strengthening Europe’s defenses, “drone wall” or not.

Justin Bronk from RUSI highlighted the risk of increased Russian aggression against NATO and emphasized the need for effective responses.

Bronk stressed the importance of boosting capabilities to efficiently counter Russian UAVs, highlighting current inadequacies.

Right now, Bronk added, “we’re not ready.”
