NATO Article 4 operates as an early-warning mechanism, enabling allies to align swiftly on proactive steps rather than reactive ones. Its use today reflects growing concerns that local boundary incidents could escalate into direct confrontations, dragging NATO deeper into the evolving war in Ukraine—or beyond.
