Will Trump's New World Order Leave Europe Behind? Navigating Uncertain Alliances

For 80 years, the bond between the United States and Europe hinged on a commitment to defend democracy and uphold a rules-based international order. This framework, initiated by President Harry Truman in 1947, aimed at countering Soviet expansion and fostering frameworks like Nato, the World Bank, and the United Nations. However, a new US National Security Strategy (NSS) unveiled in December suggests a significant shift in this paradigm, indicating an end to the longstanding joint commitment as it quotes the ’rules-based international order’ with skepticism.

Vice-President JD Vance forecasted this shift earlier in 2025, suggesting that the true threat to Europe lies not in external forces like Russia, but in internal censorship and erosion of democratic values. This view has been echoed by Karin von Hippel, who warns that the U.S. is moving away from its historical role as a promoter of global democratic values.

Critics like Victoria Coates highlight a growing anti-American sentiment within international institutions and propose that the U.S. is positioning itself in a world increasingly influenced by China and more authoritarian regimes. The new NSS advocates for a return to nation-state sovereignty, showing disdain for supranational entities that diminish individual countries’ authority, thereby signaling a potential rollback of international cooperation.

The document also reflects on the Monroe Doctrine, asserting the U.S. as the pre-eminent power in the Western Hemisphere, with particular attention on Latin America and the Panama Canal as vital interests. The U.S. intends to counter Chinese influence in the region while positioning itself to recalibrate its relations with traditionally allied nations, including those in the Middle East. The NSS emphasizes accepting regional characteristics rather than reshaping them, which contrasts sharply with the approach towards European allies.

As Europe grapples with its future role, the NSS is critical of its current trajectory, labeling its declining economic stature and demographic changes as potential threats. Independent European action is seen as essential, yet, experts argue Europe remains significantly reliant on U.S. support despite desires for operational independence.

The discussion resonates with wider concerns shared across both sides of the Atlantic about immigration, economic disparity, and a growing cultural divide. The NSS promises to align U.S. foreign policy more closely with nationalist sentiments, which could redefine how Europe and the U.S. collaborate moving forward.

Ultimately, this document reveals more than just an ideological rift; it highlights a complex landscape where both Europe and the U.S. must navigate their interconnected, yet increasingly divergent paths in a rapidly changing world.
