This thesis examines the European Peace Facility and more specifically how this off-      budget fund has been put into effect in Ukraine in light of the recent events of the Russian invasion of 2022.  This thesis will carry out a single case study about how the European Peace Facility (EPF) has been established in support of Ukraine since the end of February 2022. It will also analyse data that concerns the support provided by Member States to Ukraine to provide a better picture of how the EPF has been implemented in Ukraine. The topic can be deemed to be remarkably recent since the situation in Ukraine is still in rapid development. This is proved by the fact that European Union’s Council Decisions that are analysed in this dissertation are still being further amended. Moreover, the topic is relevant for the field of European Studies since it provides a preliminary study of these unprecedented matters that have had a profound impact on the EU. Theories of Intergovernmentalism and Supranationalism will be employed to analytically analyse the material.  This thesis will conclude that even though the EU bodies have had a marginal role in the implementation of the EPF, their response has been timely. The funds allocated by the decisions of the Council of the EU to support Ukraine are quite a substantial part of the whole financial reference of Facility. It is also discussed that the Member States have committed to a great extent to the support of Ukraine both in the training of Ukrainian troops through the EUMAM Ukraine and through the provision of weapons and arms to the UAF. In addition to this, the thesis draws considerations which connect the theory and the single case in question.

La protection de l’enfance en danger reste un domaine sensible. Le dispositif français veille à répondre au mieux aux différentes situations auxquelles le mineur peut être confronté, mais les dysfonctionnements relevés ces dernières années conduisent le législateur à réorganiser le système de protection. En réponse aux attentes des professionnels, la loi du 5 mars 2007 réformant la protection de l’enfance a donc procédé à de nombreux aménagements. Pour autant, la réforme peine à se mettre en place en pratique. Les déceptions occasionnées invitent à réévaluer le système instauré. L’étude du dispositif de protection de l’enfance rend compte de son indispensable perfectionnement. La mise en perspective d’une nouvelle réforme se fait dès lors rapidement sentir en raison de l’insuffisance des critères d’intervention et de l’inadaptation des traitements. Ce bilan en demi-teinte conduit à rechercher des solutions qui pourraient être empruntées aux systèmes étrangers, qui, comme la France, reposent sur un modèle déjudiciarisé. Peu à peu, la mise en œuvre d’une nouvelle réforme de la protection de l’enfance paraît inévitable. L’amélioration du dispositif français de protection passe par deux types d’interventions essentielles. D’une part, la redéfinition des critères et l’amélioration des mesures de prise en charge devraient permettre un véritable réajustement substantiel du dispositif de protection de l’enfance. D’autre part, la refonte formelle de ce même dispositif pourrait se réaliser par le biais d’une réelle redistribution des compétences et l’élaboration d’un code uniquement consacré à la protection des mineurs et des jeunes majeurs. Ce n’est qu’à l’issue d’une telle réforme que le dispositif de protection de l’enfance pourra être considéré comme étant à la hauteur de ses ambitions. / The protection of children at risk remains a sensitive area. The French law system ensures to respond to the different situations that children may face, but the recently identified dysfunctions led the legislator (or lawmaker) to reorganize the system of protection. The law of March 5, 2007 on children’s protection brought many updates in response to the professionnals’ needs. However, the reform is struggling to be implemented in practice. The occasioned disappointments invite to reevaluate this system.The study of the protective plan of childhood brings to the conclusion of an obvious need for implementation. The perspective of a new reform appears necessary due to the lack of intervention criterias and inadequate treatments. This mixed satisfaction review leeds to find solutions that could be inspired from foreign systems, which, like in France, rely on a judicialized model. Gradually, the implementation of a new reform of children protection seems inevitable (or unavoidable). The improvement of the French protection plan, goes through two types of essential contributions. First, the redefinition of criterias and the improvement of measures of support should allow a substantial readjustment of children’s protection plan. Second, the complete redesign of the same plan could be achieved through a redistribution of skills and the development of a code dedicated to the protection of minors and young adults. It is only after such a reform that the children’s protection plan could be considered successful in meeting its ambitions.
