Under Chapter VII of the Charter of the United Nations, the Security Council has legally binding decisions on Member States using Article 39, if there is any “threat to the peace, breach of peace, or act of aggression.” After forty-five years of deadlock due to the veto of one of the P5 members, the post Cold War era represents the boom of the UNSC until 2015. After giving an overview of the international environment, this paper seeks to describe the increase in the use of Chapter VII Resolutions by the Council to show its rebound by adjusting itself to the contemporary challenges. The comeback shows two trends. The first one is the promotion of peace through peacekeeping operations, international criminal courts or even with targeted sanctions. In 1999, after the failure of promoting peace at all costs, the fight against terrorism became the new hobby horse of the Security Council. Thus, it tried to deliver an international legal framework on counter-terrorism by adopting several Resolutions, despite the absence of a clear definition of terrorism. The growing popularity of Chapter VII Resolutions is scrutinized here by taking into account its mitigated balance.
