The geopolitical order has fundamentally shifted back toward competition for physical resources and maritime control, eroding the economic interdependence that defined the post-Cold War era. China and Europe now face acute vulnerabilities in their resource dependencies that the United States largely avoids.

China's reliance on imports flowing through contested sea lanes, particularly the Strait of Malacca, exposes its economy to blockade risk. Europe depends on external sources for energy and minerals while lacking secure maritime routes to guarantee supplies. The Ukraine war accelerated this exposure by disrupting grain and energy markets, forcing both powers to compete desperately for finite resources.

The United States occupies a structural advantage. It controls critical sea lanes through allied naval power, produces significant domestic energy and food supplies, and commands the dollar system that finances global trade. American monetary dominance remains the foundation of geopolitical leverage.

This return to resource-based competition resurrects 19th-century strategic thinking. Alfred Mahan's theories about sea power determining great power status have renewed relevance. Control over shipping chokepoints, energy reserves, and agricultural production now shapes bilateral negotiations and military planning.

For Europe, this means accelerating efforts to secure alternative energy sources and build redundant supply chains away from Russian dependencies. For China, diversifying import sources and protecting maritime access becomes existential strategy. Both face years of elevated resource costs and strategic vulnerability.

The Biden and Trump administrations have recognized this shift. U.S. policy increasingly focuses on allied naval coordination, containing Chinese expansion in the South China Sea, and reshoring critical manufacturing.

The lesson extends beyond economics. Hard power matters again. Geography constrains options. Nations cannot assume stable, cheap access to resources. Military capability directly influences economic security. This environment favors large, geographically diverse powers with strong navies and domestic production capacity.

THE BOTTOM LINE: The global economy has reverted to competition over physical
