The idea of a collective European defence force is as old as the European integration project itself. However, it has always been outshone by NATO and deemed too logistically and politically arduous for a supranational body that was excelling in projecting soft power. Fast-forward to 2025, three years into Russia’s full-scale invasion of Ukraine and only a few months into Trump’s second term, which has included a great deal of NATO- and Europe-criticism, suggesting that the United States might no longer help defend Europe. The idea of deepened European defence integration, perhaps even a sovereign European army, is no longer so far-fetched. Can the EU make use of its single market to harness its defence capabilities and work around the political divisions on foreign and security policy within the Union?
