A Russian tanker damaged the Estlink 2 power cable connecting Estonia and Finland across the Baltic Sea on Christmas Day. This action has significantly disrupted electricity supplies to Estonia. The vessel, Eagle S, did so by deliberately dragging its anchor across the sea floor. Two other cables were damaged in the same incident.
On Dec. 26, Finnish coast guard special forces boarded the Eagle S, detained its crew, and moved the vessel into a Finnish port.
Finland has thus offered a masterclass in how to deal with Russian aggression, Namely, by matching rapid intelligence assessments to proportionate, decisive action. Finland has set an example here by taking less than 24 hours to respond in the only manner that Russia would respect: with counterforce.
