Alarm Grows Over Weakened Militaries and Empty Arsenals in Europe
December 12, 2023
Budget cuts and an eroded weapons industry have hollowed out armed services; Russia’s invasion of Ukraine reveals risks “People may say the Russians have taken it on the chin, and we don’t need to worry. That’s a valid point, but it ignores residual Russian strength,” said John Deni, a professor at the U.S. Army War College and an expert on European militaries. “If the Russians present us with a mass problem in Europe, the challenge is, can technology and advanced capabilities do it? And there we see some challenges.” Article quote and background image from: https://www.wsj.com/world/europe/alarm-nato-weak-military-empty-arsenals-europe-a72b23f4

2023 Annual Estimate of the Strategic Security Environment
August 24, 2023
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. https://press.armywarcollege.edu/monographs/962/
