Résumé
UNSC resolution 2151 recalls “the sovereign right and the primary responsibility of the country concerned to determine the national approach and priorities of security sector reform and (recognizes) that it should be a nationally owned process”. But is Kosovo a state or only half a state, considering that it is not a member of the United Nations Organisation and that, for 50% of the sovereign states, it is only an autonomous province of Serbia?Secondly, considering that the UNSC resolution 1244 and the SRSG regulation 1999/24 completely cancel the portion of the Republic of Serbia’s security system situated in Kosovo, it is difficult to speak about a “reform” of the so-called security system. In this case, the expression “security system building” as included in a “peace building” and in a “state building” would be more appropriate.Nevertheless, after 25 years of transition toward an uncertain final desired state, and of peace building in a hostile context, there exists a security system in Kosovo, including a criminal code, a police service, an agency for prevention of corruption, a commercial court, a prosecutorial council, a judicial council, a constitutional court… and even a ministry of defence and a Kosovo Security Force “a multi-ethnic, professional, armed and legal military force, serving at home and abroad...” From an historic point of view, it seems interesting to see how it was built, step after step, following the fluctuations of the transition process initiated by the resolution 1244
