NATO Launches 'Arctic Sentry' to Coordinate Security Operations in the High North

Allies cast the move as centralizing existing Arctic exercises under one command to reassure Washington.

Overview

  • NATO confirmed the creation of Arctic Sentry on February 11 to consolidate allied activity across the Arctic under a single command structure.
  • The step follows President Donald Trump’s January meeting with Secretary General Mark Rutte in Davos, with European allies now seeking to bolster their role to avert further rifts.
  • Officials say the activity will primarily align ongoing exercises such as Denmark’s Arctic Endurance and Norway’s planned Cold Response.
  • NATO diplomats report that potential naval or ground operations, including on Greenland, remain under consideration with no concrete deployments decided.
  • Russia warned it will take counter‑measures, including military‑technical responses, if Western forces militarize Greenland, while Denmark and Greenland reject any transfer of sovereignty.
