Within a few years of the U.S. colonization of Cuba and the Philippines, President Theodore Roosevelt elaborated on the U.S. world mission. He spoke of the necessity of promoting peace and justice in the world: a project that required adequate military capabilities both for “securing respect for itself and of doing good to others.” To those who claim that the United States seeks material advantage in its activist policy toward the countries of the Western Hemisphere, Roosevelt responded that such claims were untrue. The U.S., he said, is motivated by altruism: “All that this country desires is to see the neighboring countries stable, orderly, and prosperous. Any country whose people conduct themselves well can count upon our hearty friendship.”
Cuba was an example, he said: “If every country washed by the Caribbean Sea would show the progress in stable and just civilization which with the aid of the Platt Amendment Cuba has shown since our troops left the island, and which so many of the republics in both Americas are constantly and brilliantly showing, all questions of interference by the Nation with their affairs would be at an end.”
He assured Latin Americans in this address to Congress in 1904 that if “….if they thus obey the primary laws of civilized society they may rest assured that they will be treated by us in a spirit of cordial and helpful sympathy. We would interfere with them only in the last resort….” (“Roosevelt Corollary to the Monroe Doctrine,” President’s Annual Message to Congress, December 6, 1904).
During a presentation in Norway in 1910 Roosevelt praised the U.S. for leaving Cuba as promised after the war to return only temporarily because of “a disaster…a revolution” such that “we were obliged to land troops again.”
The President proudly declared: “And before I left the Presidency Cuba resumed its career as a separate republic, holding its head erect as a sovereign state among the other nations of the earth. All that our people want is just exactly what the Cuban people themselves want—that is, a continuance of order within the island, and peace and prosperity, so that there shall be no shadow of an excuse for any outside intervention.” (“the Colonial Policy of the United States,” An Address Delivered at Christiania, Norway, May 5, 1910).
Earlier on January 18, 1909, to the Methodist Episcopal Church (“The Expansion of the White Races”) Roosevelt applauded the increasing presence--he estimated 100 million people—of “European races” throughout the world. The indigenous peoples of the Western Hemisphere have been assimilated with their “intruders” with the end result “that the Indian population of America is larger today than it was when Columbus discovered the continent and stands on a far higher plane of happiness and efficiency.”
And to highlight the missionary message Roosevelt added: “Of course the best that can happen to any people that has not already a high civilization of its own is to assimilate and profit by American or European ideas, the ideas of civilization and Christianity, without submitting to alien control; but such control, in spite of all its defects, is in a very large number of cases the prerequisite condition to the moral and material advance of the peoples who dwell in the darker corners of the earth.”
The "Trump Corollary" Articulated in the Newly Released National Security Strategy (November 2025)
"We want to ensure that the Western Hemisphere remains reasonably stable and well-governed enough to prevent and discourage mass migration to the United States; we want a Hemisphere whose governments cooperate with us against narco-terrorists, cartels, and other transnational criminal organizations; we want a Hemisphere that remains free of hostile foreign incursion or ownership of key assets, and that supports critical supply chains; and we want to ensure our continued access to key strategic locations. In other words, we will assert and enforce a “Trump Corollary” to the Monroe Doctrine;"

Congress has mandated that each new administration articulate its foreign policy views and priorities for the years ahead. The document referred to above illuminates and describes the visions and policies of the Trump Administration. The document articulates the failures of the post-Cold War policies of prior administrations and articulates an "American First" foreign policy of military projection, insisting on allies to pay more for defense, solidifying global access to US military forces and commerce, and reasserting US hegemony in the Western Hemisphere.
As to the Western Hemisphere the document says:
-"We must look to expand our network in the region"
-The National Security Council will "immediately begin a robust interagency process to task agencies...to identify strategic points and resources..."
-"Non-Hemispheric competitors have made major inroads in our Hemisphere..."
-Prior administrations have allowed the imposition of outside influence to happen: "another great American strategic mistake of recent decades."
-To rollback outside influence in the Hemisphere as to "espionage, cybersecurity, debt-traps, and other ways" the U.S. should "leverage in finance and technology to induce countries to reject such assistance."
-In Latin America and around the world the US "should make clear that American goods, services, and technologies are a far better buy in the long run...requiring closer collaboration between the U.S. Government and the American private sector."
And the document suggests that the "Trump Corollary" is not just about the Western Hemisphere but also foresees a worldwide struggle against Chinese influence particularly in the Indo-Pacific region. "the source of almost half the world's GDP based on purchasing power parity (PPP)."
Recognizing the Chinese economic challenge the document asserts that what makes America different is "our openness, transparency, trustworthiness, commitment to freedom and innovation, and free market capitalism..." And while the struggle with China for a world presence is largely economic, "a favorable conventional military balance remains an essential component of strategic competition."
The document includes discussions of the Middle East, Africa, and the revitalization of Europe. In his cover letter Trump boasts of the correctives that have occurred in United States foreign policy in the first nine months of his second term: "we have brought our nation-and the world- back from the brink of catastrophe and disaster...No administration in history has achieved so dramatic a turnaround in so short a time."
Conclusion
What the National Security Strategy document underscores is the intellectual background of what has been clearly observed about US foreign policy:
--a worldwide campaign to override any challenges to US economic and military hegemony.
--the maintenance and enhancement of a national security apparatus including a trillion-dollar military budget, a warfighting and interventionist capacity, a hybrid war campaign, murder on the high seas
--an ideological rationale that celebrates "free enterprise" capitalism, a mythology about American Democracy, the superiority of "the white race," the demonization of diversity, equity, and inclusion, and the likeminded demonization of "immigrants."
--All the demons that have been articulated by Trump are enshrined in the idea and the practice of the Global South.
And finally, the theory and practice of the National Security Strategy document is an update of the theory and practice articulated by Theodore Roosevelt since the so-called Spanish-American War as US industrial capitalism and militarism became a global force.
