Abstract and Keywords

“National security” is one of the most ubiquitous terms in use in politics today—the catch-all justification for all sorts of actions taken by governments (and often the easiest way to justify budget requests). When the term first began to enter general use, it was often understood in terms of protecting a country against internal subversion and external military attack, but over time its definition has expanded to cover anything that poses a threat to a country’s ability to wield the tools of statecraft or that compromises the security and freedoms of its citizenry. In the twenty-first century, it is generally accepted that, alongside military matters, national security must encompass other concerns, including economic, climate, energy, and cyber issues.

Keywords: national security, foreign policy, defense economics, national interests, grand strategy, military
