EuroUS

EuroUS is a term used to describe a proposed or hypothetical framework for deeper integration between Europe and the United States across economic, political, and security domains. The term is not an official designation and there is no treaty establishing a EuroUS. Proponents envision a transatlantic bloc with harmonized standards, streamlined trade rules, shared regulatory governance, and coordinated foreign and defense policy. In practice, discussions have focused on the Transatlantic Trade and Investment Partnership (TTIP) proposed in the 2010s and the European Union–United States TEC (Transatlantic Economic Council) as steps toward closer alignment. TTIP aimed to reduce barriers and standardize regulations, while TEC provided a platform for high-level economic coordination but did not create a formal union.

Economic integration under a EuroUS would involve large-scale market access, synchronized antitrust and competition policies, and interoperable digital infrastructure, while data flows would require alignment of privacy and data protection regimes across GDPR and US law. On security, a EuroUS would suggest intensified defense cooperation and a common strategic framework, potentially including joint procurement, intelligence sharing, and a coordinated response to global threats.

Critics argue that such a framework would face sovereignty constraints, domestic political division, regulatory divergence, and privacy concerns. They also note that historical attempts to forge a formal transatlantic fusion have stalled over legal, political, and economic obstacles. As of today, EuroUS remains a concept used in policy debates rather than a concrete political entity.
