The prospect of Donald Trump’s return to the White House represents a significant challenge for the European Union but also a potential catalyst for greater strategic autonomy. Trump’s earlier presidency demonstrated skepticism toward NATO, transactional diplomacy, and unpredictable policies, raising doubts about America’s reliability as Europe’s security guarantor.

A second Trump term would likely amplify these concerns. European states would anticipate renewed US pressure on defense spending, reduced commitments to NATO, and possible troop withdrawals. Such uncertainty strengthens arguments for Europe to invest in independent defense capabilities. Initiatives like PESCO and the European Defence Fund would gain urgency, aiming to build a credible defense industry, enhance interoperability, and reduce reliance on Washington.

Economically, Trump’s protectionist approach—tariffs, trade disputes, and efforts to reconfigure supply chains—would reinforce Europe’s drive toward self-reliance. The EU would accelerate investments in green technologies, digital sovereignty, and critical industries like semiconductors, aiming to reduce external dependencies and ensure competitiveness.

Thus, Trump’s potential return may jolt Europe into consolidating strategic autonomy, not only in defense but also in economic and technological revival. Rather than destabilizing the EU, it could accelerate its maturation into a more self-sufficient global actor.
