The European Union is preparing for a more challenging relationship with the newly elected U.S. President Donald Trump. Following Russia’s aggression in Ukraine and economic turmoil in Europe, Trump’s victory signals a marked shift away from transatlantic ties. With the return of ‘America First’ policies, Europe faces potential economic setbacks from higher tariffs and increased competition for businesses. Concerns about European security loom large, as Trump has indicated a reduced U.S. commitment, pressing European nations to bolster military spending. The effectiveness of EU unity in addressing these challenges is under scrutiny.
