The concept of a 'war economy' for Europe has gained traction as a response to shifting global alliances and the potential for a reduction in U.S. military and financial commitments. Proponents argue that Europe can no longer rely on external security guarantees and must instead leverage its own industrial base to maintain sovereignty. This shift would necessitate a fundamental restructuring of European fiscal policy, prioritizing defense spending and military production over traditional economic growth metrics.

While the necessity of increased defense spending is widely acknowledged, the methods for achieving this remain a point of debate. Some economists suggest that a transition to a war economy could stimulate industrial innovation and job creation in the defense sector. Conversely, critics warn that such a pivot could lead to significant inflation, a reduction in social services, and the crowding out of private investment in non-defense industries. The central tension lies in whether Europe can sustain its current standard of living while simultaneously funding a massive expansion of its military-industrial complex. The discussion is currently framed by the assumption that the current geopolitical climate is a long-term reality rather than a temporary crisis, though there is little consensus on how long such an economic mobilization would need to persist to be effective.
