**Russia's ongoing war in Ukraine continues to tie down significant military resources, reducing the near-term likelihood of a direct conventional attack on NATO territory that would trigger Article 5.** As of June 2026, Russian forces remain focused on incremental gains in Donbas amid battlefield stalemate and domestic constraints, while Dutch intelligence and other assessments indicate Moscow views a broader conventional challenge to the alliance as unrealistic until after hostilities in Ukraine subside. NATO has reinforced its eastern flank with additional deployments and high-readiness forces, and recent summits (including The Hague) have reaffirmed collective defense commitments, further raising the costs of any overt aggression. Traders instead price in elevated hybrid and gray-zone activity—such as sabotage, airspace probes, and infrastructure attacks—below the armed-attack threshold for Article 5 invocation. Historical precedent reinforces this view: the clause has been triggered only once, after 9/11. With roughly six months remaining before 2027, the combination of Russian capacity limits, NATO deterrence posture, and preference for sub-threshold pressure supports the 91% implied probability that Article 5 will not be invoked.
