The United States National Defence strategy of 2026 is 1 of the most groundbreaking strategy papers of the 21st century to date, as it not only sets the directions for the improvement of the US Armed Forces but besides indirectly reflects a profound change in the global safety order. This paper is not just a military plan, but a broad geopolitical declaration showing how the US sees its function in the world, what risks they consider crucial and what priorities they intend to prosecute in the coming years. Compared to the 2018 and 2022 National Defence Strategies, the fresh paper clearly departs from the US's imagination as a global "policeman" who is able to respond simultaneously to crises in all region of the world. Instead, it introduces the rule of concentration of forces, resources and responsibilities in which the safety of its own territory and the direct national interests are placed above all another obligations.
