This thesis defines and discusses the terms such as “small state” (a state of small importance in international affairs and state which lacks power) and “small power” (which is a state with power and opportunity to achieve its interests and influence the international relations no matter its quantitiy limits). The concept of national interest is discussed and is elaborated along with the various forms of Croatia's national interests throughout the history. Croatia's foreign policy has drafted and implemented three national interests since 1992: recognition as a sovereign state (international recognition), territorial integrity and Euro-Atlantic integration process. Croatia's foreign policy today, after achieving mentioned goals, roams in foreign policy field and does not have a clear, cohesive, strategic vision of where Croatia and its people should be heading. This policy roaming and wandering is a direct consequence of the lack of both the consensual national interest and the foreign policy strategy. Hence, government is obliged to come up with consensual agreement on national interest, as well as to design the finest foreign policy agenda suited for achieving that national interest. That implies building special relations with US, being an active member of EU and the proponent for the Three Seas Initiative. Also, foreign policy should, using created niches, enrich, empower and help in execution of European policy of enlargement in the area of West Balkans, which is a close Croatian’s surrounding filled with problems that could eventually spill over. Croatia has to work on europeanisation and pacification of West Balkans because only through that Croatia can be safe and prosperous. This paper also suggests that Croatia should take a more proactive stance in foreign politics, in a similar way as it was done by becoming an active member of the Three Seas Initiative.
