The Trump Corollary to the Monroe Doctrine: Reviving U.S. Influence in the Western Hemisphere

Introduction: The Monroe Doctrine and Its Modern Revival

The fifth president of the United States, James Monroe, established the Monroe Doctrine as a guide in the conduct of the nation’s foreign relations in 1823. Essentially, it laid the foundations for the superiority of America over the Western Hemisphere and protected it from any European intervention. Not exactly an act in the form of law in the United States, it has been influencing the conduct of America’s foreign relations for two hundred years.

Notably, during the Trump administration (2017–2021), the administration revived and expanded aspects of this doctrine. Observers view the Trump Corollary as a strategy to strengthen U.S. influence and counter foreign rivals in the hemisphere.

The Trump Corollary to the Monroe Doctrine Explained

This Trump Corollary to the Monroe Doctrine refers to U.S. policies emphasizing a stronger stance on security, immigration, and economic competition in the region. The Trump Corollary aims to “maintain U.S. preeminence in the hemisphere and protect Americans from ‘dangerous threats.’

To show how the Trump Corollary connects with critiques of U.S. global strategy, consider economist Michael Hudson’s Super Imperialism. Furthermore, in his book, Hudson argues that U.S. dominance now relies more on financial tools — including control of the dollar and institutions like the IMF and World Bank — than on traditional military power

“Super Imperialism is about how America is different from European colonialism by controlling the world financially and covertly, politically, not by military force.” — Geopolitical Economy Report on Super Imperialism

Economic Power and Strategic Focus

Moreover, from an economic perspective, the Trump Corollary to the Monroe Doctrine is in line with economic goals, including the attempt to prevent any foreign influence in vital infrastructure and trade routes. This aspect brings together global politics and economic policy, asserting that stability in the hemisphere and economic dominance by the U.S. are one and the same thing. Hudson argues that financial mechanisms and global institutions can be used to advance hemispheric strategic goals.

Historical Corollaries to the Monroe Doctrine

The evolution of U.S. policy in the Americas has included various extensions of the original doctrine:

  • Olney Corollary (1895) — Asserted U.S. arbitration in Western Hemisphere disputes.
  • Roosevelt Corollary (1904) — Expanded U.S. police powers to intervene in unstable Latin American countries.
  • Lodge Corollary (1912) — Opposed foreign control of strategic land or infrastructure.
  • Trump Corollary to the Monroe Doctrine (2017–2021) — A term describing the Trump administration’s renewed interventionist rhetoric and national security actions.

Conclusion

The Trump Corollary to the Monroe Doctrine reinterprets the original, reflecting a modern U.S. role in the Western Hemisphere. It incorporates ideas like Hudson’s “Super Imperialism” to show how finance and economics intersect with geopolitical strategy.
