This document discusses the evolution of strategic studies from a traditional military focus to a broader conception of security. It defines strategy as how goals are achieved under uncertain conditions. Traditional strategy referred to military operations, but after World Wars I and II, security grew to encompass all state resources and interests. The Cold War saw proxy wars and an arms race as core powers pursued security. 9/11 created new threats like terrorism that require non-military strategies. Strategic studies now considers a broader range of factors, including human nature, international anarchy, and ethics, compared to realism's narrow focus on conflict and force.
