The Trump administration has issued a stark warning to Europe in its newly released National Security Strategy, claiming that the continent risks losing its 'Western identity' within two decades if current trends continue. The 33-page document outlines the United States’ global vision, military priorities, and political strategies, emphasizing concerns over immigration, declining birth rates, and restrictions on free speech as key threats to Europe’s stability. European leaders have reacted sharply to the report, with Germany’s Foreign Minister Johann Wadephul rejecting the notion that Europe needs external advice on its social values. He reaffirmed the U.S. as a vital NATO ally but criticized the inclusion of cultural and ideological issues in a security strategy. European media outlets noted that the tone of the document echoes Trump’s earlier United Nations speech, where he criticized Western Europe’s immigration and energy policies. The strategy also highlights the growing influence of nationalist movements in Europe, which Washington views favorably, and calls for deeper U.S. involvement in managing Europe’s relationship with Russia. Analysts suggest the document could shape future transatlantic relations and defense policies.
