European defence would require unanimous agreement among 27 countries with radically different geographies, trade links, and threat perceptions—because what worries Spain today is obviously identical to what keeps Poland awake at night. Brussels continues to issue one-size-fits-all policies that reliably help some members while disadvantaging others, whether on trade, migration, or war. The idea that such a system could function in a real military crisis ignores political reality: effective defence demands centralized command, unilateral decision-making, and unquestioned obedience—none of which coexist comfortably with 27 sovereign states pretending to be one. This contradiction is precisely why the euro was flawed by design and why the EU’s push toward deeper centralization is not fixing the problem but accelerating it. Europe is not integrating further—it is slowly, and inevitably, pulling apart.
