In line with the European Commission’s Fundamentals first approach, Chapters 23 and 24 are the first to open and the last to close in accession negotiations. Many CSOs focus their activities on Chapter 23 (Judiciary and Fundamental Rights), which is also recognized by donors. Despite its scope and importance, as well as the obvious problems that the state has in this area of policy, Chapter 24 (Justice, Freedom and Security), however, remains out of focus of the actors, due to lack of capacity, limited donor support, insufficient networking, low transparency of security institutions and unsatisfactory information of organizations. In the past, EUROTHINK has been working to address these shortcomings by developing its own portfolio and working capacity in the chapter. The organization participated, with two representatives, in the working groups in charge of creating the package of laws for reform of the security-intelligence community. EUROTHINK, in cooperation with partners from Serbia and Montenegro, is working on a comparative regional analysis of the role of security services in capturing countries in the region. The organization participates in a large European consortium working on the implementation of the Horizon 2020 project related to migration. Within the Structural Dialogue Platform, EUROTHINK monitors the work of the Sectoral Working Group on Internal Affairs. The organization is also well networked with key organizations and individuals who are considered authorities for the growth and suppression of violent extremism. The Eurometer survey incorporates security issues. At the same time, EUROTHINK monitors the process and benefits of the country’s accession to NATO, especially the aspects that are complementary to the EU accession process. In the coming years, EUROTHINK will deal with these issues in a more structured and focused way through the development of the “Security, Justice and Home Affairs” program. EUROTHINK will strive for a transparent and accountable security sector, which will be able to deal effectively and efficiently with modern security threats. More specifically, within this program, the activities will be focused on the following areas: 1) Good governance in the security sector through the promotion of transparent and accountable institutions, which are subject to strong democratic oversight and control; 2) Public security, fight against organized crime and corruption; 3) Dealing with and preventing threats, challenges, vulnerabilities and risks to national security (such as terrorism, violent extremism, cyber-threats, external hybrid threats, etc.); 4) International security; 5) Migration, asylum and freedom of movement.
