On 23 September, NATO issued a strong warning to Russia after repeated airspace violations, including a recent incursion last Friday by three Russian fighter jets into Estonian airspace. The incident led Estonia to invoke Article 4 of the NATO treaty and reflects a broader pattern of rising Russian aggression along the alliance’s eastern flank. NATO reaffirmed its commitment to collective defense under Article 5, warning it will employ all necessary measures to deter threats. The escalation heightens regional instability and the risk of miscalculation, with potential implications for business operations in the Baltic region
