The sense of nations for cooperation. How threat perception and ideology influence counterterrorism cooperation between EU members.

Which factors influence bilateral counterterrorism (CT) cooperation between EU Member States? Although scholars have studied European CT, the question still needs to be answered. This paper addresses the issue by introducing a new theoretical framework that combines CT and Foreign Policy Analysis (FPA) literature. As citizens' threat perception increases, governments are pressed to act. Overall, centrist cabinets tend to rely more on cooperation agreements; likewise, pushed by threat perception, left-wing executives also recourse to international cooperation. I tested this framework on a newly collected dataset, which comprehends bilateral CT agreements signed among EU Members from 2002 to 2017. As such, this paper fosters studies on EU CT, focusing on a less debated issue: bilateral cooperation between EU Member States. The results support the initial hypotheses, disclosing a robust influence of threat perception and cabinet ideology on the number of bilateral CT agreements signed. Furthermore, they show that the perception of the threat is more influential on cooperation than the actual impact of terrorism. [ABSTRACT FROM AUTHOR]
