Donald Trump's foreign and economic policies have indeed caused significant shifts, often described as "seismic." His "America First" doctrine has reshaped U.S. relations with allies and adversaries alike, emphasizing unilateralism, economic protectionism, and a transactional approach to diplomacy.
For example, his administration's recent pivot toward Russia, including suspending military aid to Ukraine and engaging in direct negotiations with Moscow, has raised concerns about the future of NATO and U.S. commitments to European security. Similarly, his aggressive tariff policies have sparked fears of a global trade war, with potential long-term consequences for international markets and supply chains.
If these changes were to become permanent, they could signal a shift away from the post-World War II liberal order, where the U.S. played a central role in maintaining global stability.
This could lead to a more fragmented world, with regional powers like China and Russia filling the vacuum left by a less engaged U.S.. At the same time, it might push traditional allies to strengthen their own defense and economic strategies, as seen in Europe’s recent moves to boost military spending.
