Is a strong and cohesive European Union more in the interest of the United States of America than a fragmented European Union

U.S. benefits more from a strong, unified EU than a weak, divided Europe

Economic and trade impact

Single Market simplification for U.S. multinationals: The EU Single Market’s “four freedoms” and mutual recognition let firms scale once for a 450+ million consumer market, reducing duplicative product approvals, customs friction, and regulatory fragmentation—far simpler than dealing with 27 separate regimes.

Leverage in trade: bloc vs. nations: Negotiating with a unified EU concentrates bargaining power on their side, but it also yields predictable, comprehensive outcomes. Fragmented bilateral talks might appear to offer tactical U.S. leverage, yet the EU’s single voice in goods trade has grown to rival U.S. trade volumes, making bloc-level agreements more durable.

Unified regulations and compliance costs (GDPR): Harmonized rules like GDPR replace 27 divergent privacy regimes; while compliance is costly, one framework avoids a patchwork of incompatible national laws and fines.

Euro as reserve currency and U.S. dollar hegemony: The dollar remains dominant (about 54% of reserves vs. ~19% for the euro), so the euro functions more as a stabilizing check than a fundamental undermining of U.S. financial primacy.

Dismantling EU and $5T+ two-way investment: Unraveling the EU would fragment regulatory certainty and capital markets, risking the transatlantic investment stock—now estimated around $7.4 trillion—which underpins productivity and jobs on both sides.

“America First” deals by pitting EU states: The 2025 framework outcomes (15% tariff cap, energy pledges) were achieved with the EU as a bloc; trying to split EU members risks retaliation cycles and instability that erode U.S. gains.

U.S. ag exports if CAP dismantled: Removing CAP could open EU markets in theory but would also trigger policy uncertainty and new barriers; recent experience shows even “openings” get constrained by EU sensitivities and non-tariff measures.

EU-wide tariffs removal and U.S. deficit: Tariff tinkering rarely fixes the overall U.S. goods deficit, which is driven more by savings-investment imbalances; unilateral changes tend to raise inflation and lower GDP without curing the global gap.

Geopolitical stability and security

Unified EU as security partner: The EU has expanded defense and sanctions roles post‑Ukraine, complementing NATO and giving the U.S. a more capable, coherent counterpart on non‑military lines of effort.

If EU dismantled, U.S. military burden: A reduced or fragmented EU would force greater U.S. presence and spending to backfill capability gaps; replacing U.S. support in Europe would cost allies up to $1 trillion and take decades.

Impact on NATO: EU coordination buttresses NATO’s mobility, cyber, and sanctions work; fragmentation would strain unity and complicate force planning and resilience.

EU soft power: complement or complication: EU soft power—aid, diplomacy, standards—often amplifies U.S. goals, though it can complicate tactics; overall it broadens Western influence in regions where U.S. hard power is less welcome.
