After the November 2015 terror attacks in Paris, the French government reacted swiftly by declaring a state of emergency. This state of emergency remained in place for over two years before it was ended in November 2017, only after being replaced by the new anti-terror legislation. The attacks as well as the government’s reactions evoked parallels to 9/11 and its aftermath. This is a puzzling observation when taking into consideration that the Bush administration’s reactions have been criticized harshly and that the US ‘War on Terror’ (WoT) was initially considered a serious failure in France. We can assume that this adaption of the discourse and practices stems from a successful establishment of the WoT macro-securitization. By using Securitization Theory, we outline the development of this macro-securitization by comparing its current manifestation in France against the backdrop of its origins in the US after 9/11. We analysed securitizing moves in the discourses, as well as domestic and international emergency measure policies. We find extensive similarities with view of both; yet there are differing degrees of securitizing terrorism and the institutionalisation of the WoT in the two states. This suggests that the WoT narrative is still dominant internationally to frame the risk of terrorism as an existential threat, thus enabling repressive actions and the obstruction of a meaningful debate about the underlying problems causing terrorism in the first place.
