This chapter traces the development of the national security state as a US foreign policy actor to the early stages of the Cold War. However, the US national security state persisted in the post-Cold War era and after 9/11 experienced a massive expansion in what was called the global war on terrorism. The central argument that emerges from the chapter is that the model of the national security state is not only a potential threat to US democracy, but also constitutes an impediment to a US recognition in the 21st century that key security problems increasingly require multilateral solutions.
