This study aimed to offer an in-depth insight into intellectual dilemmas associated with a comprehensive approach to national defence using Estonia as an example to demonstrate that comprehensive approach in itself may not be enough to feel safe and secure. The authors focused on two specific theoretical questions. First, how security threats are determined in Estonia, including the impact of such a phenomenon as macro-securitization? Second, how various levels of comprehensive approach relate to each other in the way that a shared security culture will be created?
In this way, the aim of this article was not only to shake the foundations of national defence in Estonia but also to contribute to the improvement of the current model to ensure that it actually works in practice.
