Since the two narratives of strategic autonomy and European sovereignty first appeared in the EU in 2016 and 2017, they have been omnipresent.

Therefore, this paper analyzes the extent to which the EU’s Common Security and Defense policies (CSDPs) have been justified from 2016 to 2020 given the evolving TSC. In doing so, it becomes clear that the TSC is not the only explanation for the EU’s recent CSDPs but is merely one of many.
