ABSTRACT
The aim of the chapter is to outline the theoretical foundations of security economics. The first section presents the issues of defence in economic theory. The second section highlights the economic theory of alliances. The third section examines defence economics. The fourth section looks at terrorism from the point of view of rational choice theory. The fifth section analyses technology and national security. The sixth section explains security as a relative concept. The seventh section outlines international security in the times of a pandemic.
Security is not an absolute but a relative concept. Internal and external security is directly proportional to threats and risks. It cannot be viewed from extreme positions – meaning whether it is ensured totally or not at all. No country can achieve the status of absolute security. Usually, security is more or less ensured. Therefore, the relevant question is how much security is sufficient.
