Abstract
Since the “Zeitenwende” proclaimed in Spring 2022, there has been an increased focus on both internal and external security issues, such as the procurement of military goods and defense capabilities. The geopolitical dynamics towards more multipolarity are forcing Europe, and therefore Germany as well, to take greater control of its own destiny. Emancipation from former hegemons offers opportunities; at the same time, successful economic policy navigation requires the efficient use of scarce public funds. Fiscal policy and social debates are controversial. Just think of the budget proposals currently being discussed and the reintroduction of compulsory military service. This discussion explores the extent, direction and sustainable financing options for the necessary changes. What all contributions have in common is the recognition of the necessity and potential of effective coordination at the European level on the issue of military sovereignty.
