Abstract
NATO, as one of the most important security organisations, has been involved in a large number of operations of all kinds since its establishment. Peace Support Operations are the most common type, as they include conflict prevention, peacemaking, peacebuilding, peacekeeping, peace enforcement and humanitarian operations. Some states participate in these operations very often, others only rarely. This study aims to examine the participation of the Czech Republic, a small state that has a small but well-trained and specialised army. The research aims to determine the most common reasons for Czech participation in NATO’s Peace Support Operations. The work uses qualitative comparative analysis to determine the necessary reasons or sufficient conditions for the participation of this state. Five types of reasons – political reasons, security reasons, economic reasons, institutional reasons and normative reasons are tested. The analysis points to the fact that security reasons are the most important reasons.
