NATO is preparing to initiate a mission named 'Arctic Sentinel' which aims to strengthen its military and surveillance operations in the Arctic region. This comes in response to increasing tensions, particularly between the U.S. and European nations, marked by controversial statements from former President Donald Trump regarding Greenland. Five authorities corroborated this information to Reuters, underscoring the mission's urgency.

The 'Arctic Sentinel' mission could commence within the week, aligned with a scheduled meeting in Brussels where defense ministers from NATO member countries are expected to convene on Thursday. The mission is anticipated to comprise various military exercises, bolstering surveillance capacities, and the deployment of additional naval and aerial assets to the Arctic, including drones, as per insights from three European diplomats and a military official.

Despite the looming launch, sources have indicated that while the preparations are underway, details regarding the scope and specific actions of the 'Arctic Sentinel' mission have not yet been fully disclosed. The situation reflects NATO's increased focus on the Arctic as geopolitical stakes rise in a region that is becoming more strategically important in light of environmental changes and shifting international relations.
