Donald Trump's decisive victory in the 2024 U.S. presidential election has sparked widespread concern among international allies, particularly in Europe, about potential shifts in foreign policy and economic impacts. European leaders fear increased economic protectionism and tariffs, which could strain the EU's substantial trade relationship with the U.S. Trump's 'America First' policy could lead to reduced U.S. involvement in global conflicts and uncertainty over NATO commitments, causing geopolitical instability. Allies like Germany worry about the economic repercussions and political instability that Trump's presidency might trigger, especially given tensions within its own coalition government. Concerns extend to the possibility of Trump viewing authoritarian regimes as partners rather than adversaries, further complicating international relations. Amidst these tensions, some, like Hungary's Viktor Orban, see Trump's return as beneficial, highlighting divergent views within Europe.
