Russia’s Secret War: 3 Drones, Spies, and Sabotage Rock Europe as NATO Hesitates

A kamikaze drone has struck Leipzig. Spies have met at a neighborhood bar in Sundbyberg, a suburb of Stockholm. Cyberattacks, arson, and disinformation campaigns are spreading across Europe [253960]. Russia’s covert warfare is escalating — and European and NATO leaders still hesitate on how to respond [253960].

The pattern is clear: from drone strikes on European soil to intelligence operatives meeting in quiet corners of Scandinavian neighborhoods, Russia is waging a hidden war that Western officials have been slow to confront [253960].

Meanwhile, Moscow has issued a direct nuclear threat to NATO. According to a letter sent to the alliance and cited by Financial Times sources, Russia warned that blocking its exclave Kaliningrad could trigger a Russian nuclear attack on NATO countries [253900]. Kaliningrad is a Russian territory on the Baltic Sea, separated from mainland Russia and bordered by NATO members Poland and Lithuania [253900]. NATO confirmed to Swedish newspaper Dagens Nyheter that it received the letter [253900].

The two developments — covert sabotage across Europe and an explicit nuclear warning — paint a picture of a Kremlin willing to push far beyond conventional boundaries.

European and NATO leaders have yet to announce a unified response to the sabotage campaign [253960]. The hesitation comes as the threats multiply: drones, spies, cyberattacks, and now a nuclear warning over Kaliningrad [253960][253900].
