Outgoing Estonian Ambassador to NATO, Jüri Luik, asserts a significant shift in the alliance’s posture following Russia’s invasion of Ukraine. He states that prior to the full-scale invasion, NATO functioned more as a political entity than a prepared military force. The war prompted NATO to transform into a “military machine,” constantly prepared for potential conflict. Luik emphasizes that NATO’s current deterrence strategy is principally designed to influence Russian President Vladimir Putin’s calculations. The intent is to discourage further aggression by conveying a clear readiness to respond. This change reflects a fundamental reassessment of the threat posed by Russia and a commitment to collective defense. Luik’s comments highlight the critical role perception plays in modern deterrence.
