The German military has gone through fundamental changes since Reunification in 1990. Not only did its obvious enemy disappear, but the basis for what had been a partnership of convenience between German society and the Bundeswehr eroded. Since then, successive German governments have tried to find ways to transform strategic concepts, military structures, and international commitments to fit the new international relations and security challenges at the beginning of the twenty-first century. These transformation efforts have been affected both by cultural restraints and by economic ones. Instead of just following one new and simple strategic concept, the transformation of the Bundeswehr had to be oriented towards military structures that were politically and financially feasible. Despite the progress achieved on the operational level, Germany is still lacking a clear strategic concept for the use of force and the engagement of the Bundeswehr.
