The thesis analyses activities of small states (focusing on Slovenia) during their Chairmanship of Organization for Security and Co-operation in Europe (OSCE), in the field of conflict management and conflict prevention as one of the main areas of the OSCE. It analyses how a small country can put its soft power to smart use and act as an agent of preventive diplomacy and what the main obstacles for its activities are. The thesis deals with a case-study of the Kyrgyz revolution in 2005, which coincided with Slovenia’s Charimanship of the OSCE. The thesis shows that a small country’s specific characteristics bring comparative advantages in preventive diplomacy, because small countries do not engage actively in crisis resolution in pursuit of their (narrowly defined) national interests as it is often associated with big states. It also shows that organizational backing (in our case the OSCE’s) is vital for small states, because it provides legitimacy. With the analysis of Slovenia’s Chairmanship, the thesis shows that one of the main tasks for a small country, chairing an international institution, is a community action with an emphasis on the decision-making process. A successful community action brings about opportunities for a small country to prove itself in an international environment and to act as a bridge builder between different interests. With this, the small country can strengthen its international reputation and its soft power.
