**NATO maintains robust deterrence along its eastern flank amid the ongoing Russia-Ukraine conflict, with no armed attack on alliance territory recorded in recent months.** Russian forces continue limited advances inside Ukraine at a slow pace through mid-2026, while NATO allies have increased forward deployments, defense spending commitments, and equipment deliveries to Kyiv without direct confrontation. The July 2026 Ankara Summit reaffirmed Article 5 solidarity and hybrid-threat countermeasures, yet incidents such as infrastructure sabotage and airspace probes remain below the collective-defense threshold. Warnings of potential Russian tests by 2028–2029 reflect longer-term concerns rather than near-term triggers, supporting trader consensus that invocation before 2027 remains unlikely absent a major escalation.
