Russia's shadow war in Europe turns increasingly violent

# Why This Matters Russia's shift from espionage and disinformation toward kinetic attacks on European infrastructure represents a fundamental escalation that NATO members cannot ignore. The discovery of explosives at a German airport suggests Moscow is willing to accept higher risks of attribution and retaliation, potentially signaling either desperation over Ukraine's battlefield setbacks or confidence that Western responses will remain limited. This transition from covert sabotage to direct physical violence could trigger a cascade of security responses—tightened airport protocols, prepositioned air defenses, and offensive cyber operations against Russian targets—that narrow the space between hybrid conflict and conventional warfare. If such attacks continue without decisive consequences, other NATO members may conclude they must adopt more aggressive postures, creating a dangerous cycle where each side's escalatory measures provoke the next, particularly in Eastern Europe where Russia's capacity to strike is greatest.
