• Russia has built up its armed presence along its border with Finland and other EU countries.
• Finland is preparing to defend itself with a concept of 'total defense'.
• Poland is building fortifications, expanding its army, and buying tanks and drones.
• Lithuania is strengthening its defenses along its border with Belarus.

The buildup of Russian forces along NATO's eastern border may indicate a heightened threat to the alliance's new borders. Finland's emphasis on 'total defense' and Poland's fortification efforts suggest a focus on national readiness and deterrence, which could strengthen their positions against potential Russian aggression. However, the uncertainty surrounding US commitment to NATO's Article 5 may impact the alliance's overall readiness and response to a potential conflict.
