Europe Raises Hybrid Threat Alarm as NATO Rejects Imminent Attack
European leaders are worried that Russia’s conflict with Ukraine could cause problems in other European countries.
They are especially concerned about drones, cyberattacks, sabotage and false information.
Poland’s leader said Russia might use a small attack to test whether NATO countries would defend one another.
France also said the threat had grown and wants important buildings and facilities better protected.
Leaders in the Netherlands and Finland told people to take the risks seriously.
NATO says these activities are concerning, but it has not seen proof that Russia is about to launch a normal military attack on NATO.
Countries such as Germany and Lithuania are practicing emergency plans and improving preparedness.
The United Kingdom says it is ready to help defend NATO territory.
The United States is reviewing its military presence in Europe, while Poland is seeking a stronger permanent US presence.
Polish Prime Minister Donald Tusk warned that Russia could use drones or missiles against NATO countries supporting Ukraine, possibly disguising an attack as an accident.
French President Emmanuel Macron said Russia’s hybrid campaign had intensified and ordered plans to protect critical infrastructure from drone and cyberattacks.
The Netherlands and Finland urged vigilance, while Russia denied allegations of involvement in sabotage and other hybrid operations.
NATO said it had no evidence of an imminent conventional attack on allied territory, while reaffirming its commitment to collective defense.
Germany, Lithuania and NATO are expanding medical, civil-defense and military preparations, as the United States reviews its troop presence in Europe.

NATO’s Measured Assessment
NATO distinguishes increased hybrid activity from an imminent conventional military attack and says there is no evidence that one is about to occur.
Russian responsibility
European Leaders’ Warnings
