The 19th-Century Reset: How Trump’s Foreign Policy Could Reshape Global Power Dynamics
The world is witnessing a dramatic recalibration of global power, and the potential costs are staggering. A recent analysis suggests that the U.S., under President Trump, is actively dismantling the post-World War II international order at a pace not seen since the collapse of the Soviet Union – a shift that could cost trillions in lost trade and investment, and fundamentally alter the security landscape for decades to come.
From Truman’s Vision to Trump’s “Donroe Doctrine”
For nearly eight decades, the United States has been the architect of a global system built on multilateral institutions like NATO, the United Nations, and the World Trade Organization. President Truman, emerging from the ashes of WWII, envisioned a world secured by collective security and international cooperation. But that vision is now facing an existential challenge. President Trump’s approach, increasingly characterized by unilateral action and a rejection of established alliances, harkens back to a 19th-century worldview of spheres of influence and power politics.
The shift is stark. From threatening to unilaterally acquire Greenland to withdrawing from 66 international organizations, the administration signals a clear preference for a transactional, “America First” foreign policy. This isn’t simply a scaling back of engagement; it’s a fundamental redefinition of America’s role. The emergence of the “Donroe Doctrine” – a more assertive and arguably isolationist interpretation of the Monroe Doctrine – exemplifies this. Where the original doctrine aimed to prevent European interference in the Americas, Trump’s version asserts U.S. dominance with a blunt, uncompromising tone.
The Return of Spheres of Influence and Great Power Competition
The implications of this shift extend far beyond the Western Hemisphere. Analysts like Ian Bremmer of the Eurasia Group warn that Trump’s policies are accelerating a trend towards a world divided into competing spheres of influence. This echoes the geopolitical realities of the 19th century, where great powers – Britain, France, Russia – carved up the world into areas of dominance. Today, that dynamic is re-emerging, with the U.S. asserting its control over the Americas, Russia seeking to reassert its influence in Europe, and China aiming for regional hegemony in Asia.
This isn’t merely a theoretical concern. The recent U.S. intervention in Venezuela, supporting opposition figures while simultaneously engaging with elements of the Maduro regime, demonstrates a willingness to disregard established norms of democratic governance in pursuit of strategic interests. Similarly, the increased use of military force – bombing campaigns in the Middle East and Africa – coupled with threats against allies and adversaries alike, suggests a willingness to use power unilaterally, often with little regard for the consequences.
The Military Dimension: A Shift in Tactics
Hal Brands of the American Enterprise Institute points to a pattern in Trump’s military interventions: “a lot of force to hit somebody really hard, and then you let somebody else sort out the consequences.” This approach, while potentially delivering short-term tactical gains, risks destabilizing regions and creating vacuums that can be exploited by extremist groups or rival powers. It also places a disproportionate burden on allies to manage the fallout.
The Erosion of Alliances and the Future of Global Security
Perhaps the most concerning aspect of this shift is the erosion of trust with traditional allies. European nations, long reliant on U.S. security guarantees, are now hedging their bets, seeking greater autonomy and exploring alternative security arrangements. This trend, as Bremmer notes, is a long-term threat to U.S. power and influence. The willingness to align with allies has been a cornerstone of American success in projecting power globally, and Trump’s rejection of that principle is a strategic misstep.
The withdrawal from international organizations further exacerbates this problem. These institutions, while imperfect, provide a forum for dialogue, cooperation, and conflict resolution. By abandoning them, the U.S. cedes influence to rivals and undermines the rules-based international order that has maintained relative peace and stability for decades.

Navigating a More Fragmented World
The return to a 19th-century style of power politics presents significant challenges for businesses, investors, and policymakers alike. Increased geopolitical risk, trade disruptions, and the potential for armed conflict are all likely consequences. Adapting to this new reality will require a reassessment of risk management strategies, a diversification of supply chains, and a greater emphasis on regional partnerships.
The future isn’t predetermined. A course correction is still possible, but it would require a fundamental shift in U.S. foreign policy – a renewed commitment to multilateralism, a restoration of trust with allies, and a recognition that American leadership is most effective when exercised in cooperation with others.
