Germany's top military officer, Inspector General of the Bundeswehr Gen. Carsten Breuer, told the Wall Street Journal that Russia is systematically using drones to probe NATO's air defenses across Europe, actively looking for weaknesses to exploit as part of an escalating "gray-zone" hybrid strategy designed to destabilize Western governments and institutions . He called on NATO to raise its response level, stating bluntly: "Russia is testing us every day"
.
Breuer assessed that Russia is actively transitioning its economy and military strategy in anticipation of a broader, long-term confrontation with the West—not limited to the current war in Ukraine . He described the Kremlin's hybrid attacks as "probing" for NATO's vulnerabilities ahead of a potential wider conflict, and warned that Russia views the current gray-zone operations as preparation for a future expanded war
.
Multiple lines of evidence point toward Moscow, though German authorities note there is no definitive public proof directly linking the specific drone to the Kremlin as of early August 2026 :
Germany tightened security measures at Leipzig Airport and other critical infrastructure. Dobrindt said Germany faces daily hybrid warfare attacks from abroad and described a broader campaign of sabotage, espionage, and drone incursions . Poland, the Baltic states, and other NATO frontline members have been on heightened alert, cooperating with German investigators on the 2024 precursor plots
. Gen. Breuer publicly urged NATO to raise its collective response level to address the daily probing of its defenses
.
The incident at Leipzig/Halle Airport is not isolated. Authorities in Saxony have recorded dozens of drone overflights in the first half of 2026 . A September 2025 parcel bomb at the DHL center at the same airport—one of four rigged parcels dispatched from Lithuania—is also under investigation as part of a suspected Russian test run
.
Gen. Breuer's warnings and the Leipzig incident underscore a strategic shift: Russia is not merely waging a war in Ukraine but is actively preparing for a broader confrontation with NATO through hybrid means. The systematic probing of air defenses, the use of explosive drones on allied soil, and the long-term economic mobilization described by Breuer suggest the alliance faces a persistent, escalating threat that blurs the line between peacetime and conflict.
