Donald Trump's victory in the 2024 presidential election is causing significant shifts in global politics, particularly in Europe. European leaders, including French President Emmanuel Macron, have quickly congratulated Trump, indicating a scramble to adapt to his presidency, with Hungary's Viktor Orbán emerging as a notable supporter. The EU is now emphasizing the need for increased defense spending and strategic autonomy, especially in light of Trump's uncertain stance on NATO and potential cuts to U.S. support for Ukraine. Concerns are growing that Trump's administration could favor Serb interests in the Western Balkans, risking instability in regions like Bosnia and Kosovo. Analysts warn that this shift could embolden nationalist movements and disrupt existing diplomatic balances. In response, European nations may be forced to reconsider their defense strategies and alliances amidst the changing political landscape.
