Donald Trump's victory in the 2024 U.S. presidential election is poised to significantly impact Europe and the European Union, prompting a reassessment of transatlantic relations, defense strategies, and economic policies.

European leaders are expressing concern over the potential shift in U.S. foreign policy under Trump's leadership. His previous criticisms of NATO and suggestions of reducing U.S. involvement in the alliance have raised questions about the future of European security. Former U.S. Ambassador Jeffrey Hawkins warned that Europe might have to manage military threats independently if Trump withdraws U.S. security guarantees.

Hungarian Prime Minister Viktor Orbán, a Trump supporter, stated that Europe would need to reconsider its support for Ukraine if Trump adopts a pro-peace stance.

This sentiment reflects broader concerns about the continuity of U.S. support for Ukraine amid ongoing conflicts.

The prospect of a reduced U.S. commitment to European defense is likely to accelerate discussions within the EU about achieving greater strategic autonomy. The concept, which emphasizes the EU's ability to act independently in defense matters, has gained traction in recent years. European Commission President Ursula von der Leyen has advocated for a "geopolitical commission," underscoring the need for Europe to bolster its defense capabilities.

German officials have echoed this sentiment, emphasizing the importance of Europe strengthening its defense mechanisms to ensure security without over-reliance on the U.S.

Trump's "America First" policies, including potential tariffs on European goods, could strain transatlantic trade relations. The EU has been preparing for such scenarios, with plans to respond swiftly to any trade measures that may harm European economies.

Analysts warn that Trump's re-election could disrupt the global economic order, affecting European interests and objectives, particularly in areas like climate change. Goldman Sachs estimates that Trump's policies could reduce Europe's GDP by 1%.

Trump's victory may embolden populist and far-right movements across Europe, potentially influencing national politics and EU cohesion. Leaders like Orbán have openly supported Trump, and his return to power could galvanize similar political forces within the EU.

The EU's response will be crucial in shaping its future role on the global stage and ensuring stability amid shifting geopolitical landscapes.
