USA Releases New National Security Strategy; Massive Strategic Shift to the Western Hemisphere

On December 4, 2025, the US government released the latest version of its National Security Strategy (NSS), explicitly proposing to shift the focus of US military combat power and defense resources from traditional global deployments to the Western Hemisphere. The focus is on strengthening homeland defense and responding to proximal geopolitical challenges. This move marks a major shift in US foreign policy, reflecting the Trump administration's high priority on homeland security and economic sovereignty. Governments worldwide are closely evaluating the long-term impact of this change on the global security architecture.
