2023 Annual Estimate of the Strategic Security Environment
The Annual Estimate of the Strategic Security Environment serves as a guide for academics and practitioners in the defense community on the current challenges and opportunities in the strategic environment. This year’s publication outlines key strategic issues across the four broad themes of Regional Challenges and Opportunities, Domestic Challenges, Institutional Challenges, and Domains Impacting US Strategic Advantage. These themes represent a wide range of topics affecting national security and provide a global assessment of the strategic environment to help focus the defense community on research and publication. Strategic competition with the People’s Republic of China and the implications of Russia’s invasion of Ukraine remain dominant challenges to US national security interests across the globe. However, the evolving security environment also presents new and unconventional threats, such as cyberattacks, terrorism, transnational crime, and the implications of rapid technological advancements in fields such as artificial intelligence. At the same time, the US faces domestic and institutional challenges in the form of recruiting and retention shortfalls in the all-volunteer force, the prospect of contested logistics in large-scale combat operations, and the health of the US Defense Industrial Base. Furthermore, rapidly evolving security landscapes in the Arctic region and the space domain pose unique potential challenges to the Army’s strategic advantage.

What Ukraine Taught NATO about Hybrid Warfare
December 5, 2022 — The Russian invasion of Ukraine has highlighted the long-term energy dependencies on Moscow that Europe will neither be able to resolve quickly nor without great sacrifice. Russia’s hybrid warfare—a combination of kinetic strikes against key infrastructure, information manipulation, malign finance, economic coercion, and cyber operations—has used Ukraine to target the heart of Europe’s energy security. This war has forced the Continent to consider how to realize its economic, environmental, and geostrategic energy goals on its own. This study found systemic dependencies and cyber vulnerabilities in critical energy infrastructure throughout the European continent could impact the Alliance’s political stability and threaten military effectiveness. Forward mobility and troop readiness are affected directly by energy shortfalls and increasing cyber vulnerabilities across NATO. The main findings related to cyber and malign influence provide a sobering view of the challenges of hybrid warfare on energy security in NATO nations. ... MORE
