The Geopolitical Context of 1823 and the Initial Intentions

The Monroe Doctrine emerged amid the particularly tense geopolitical context of the post-Napoleonic era, when European powers—notably the Holy Alliance formed by Russia, Prussia, and Austria—sought to restore absolutist monarchies across the American continent, which had just experienced a wave of independence movements. James Monroe, who had been President of the United States since 1817, and his Secretary of State, John Quincy Adams, conceived this doctrine as a defensive measure aimed at protecting the young Latin American republics against any attempt at European colonial reconquest. The famous passage from Monroe’s message stating that the American continent, having attained and maintained its free and independent status, could no longer be considered subject to future colonization by any European power was fundamentally a declaration of collective self-determination, although it also reflected the United States’ growing desire to exercise regional hegemony. At the time, the United States lacked both the military power and the economic influence necessary to enforce this doctrine by force, which explains why it remained largely symbolic for several decades.

It is crucial to understand that the original Monroe Doctrine was not a call for American interventionism but rather an affirmation of the territorial integrity of the nations of the American continent in the face of European imperialism. Monroe himself was a veteran of the American Revolutionary War who sincerely believed in republican principles and the self-determination of peoples, although his vision was inevitably limited by the prejudices and interests of his time. The doctrine was formulated at a time when the United States was still an emerging power, seeking to protect itself from European rivalries while gradually asserting its own sphere of influence. Historians generally agree that Monroe would never have imagined that his doctrine would one day be used to justify direct U.S. military interventions against sovereign Latin American governments, as is the case today with the Donroe Doctrine. The original intention was to protect the region from foreign interference, not to serve as a justification for even more direct and aggressive U.S. interference.

When one rereads the original texts of the Monroe Doctrine from 1823, one is struck by the radical difference between James Monroe’s moderate and defensive tone and Donald Trump’s conquering aggressiveness. Monroe wrote in carefully crafted diplomatic language, taking care not to unnecessarily provoke the European powers while firmly asserting American principles. Trump, on the other hand, seems to take a malicious pleasure in creating tensions, provoking his adversaries, and turning every speech into a direct challenge. What fills me with despair is seeing how complex and nuanced historical concepts can be distorted and oversimplified to serve contemporary political agendas that are entirely foreign to their original context. The Monroe Doctrine was the product of an era when the United States positioned itself as an anti-imperialist power in opposition to Europe. Today, in the form of the Donroe Doctrine, it has become the tool of a new type of American imperialism that does not call itself by that name. How can we accept that history is being rewritten and exploited in this way without the slightest respect for historical truth?

The Evolution of the Doctrine from the 19th to the 20th Century

The transformation of the Monroe Doctrine from a defensive principle into an interventionist tool occurred gradually throughout the 19th century, as American power expanded economically and militarily. As early as the 1840s, under the presidency of James K. Polk, the doctrine was invoked to justify the United States’ territorial expansion westward and southward, notably during the annexation of Texas and the Mexican-American War, which led to the acquisition of vast territories including California, New Mexico, Arizona, Nevada, and Utah. This initial phase of expansion set a precedent whereby U.S. interests could take precedence over the sovereignty of neighboring nations—a precedent that would be amplified over time. The construction of the Panama Canal in the early years of the 20th century marked another crucial milestone in the doctrine’s evolution, illustrating how the United States could use its economic and military power to control strategic infrastructure in Latin America.

However, it was truly with the Roosevelt Corollary of 1904 that the Monroe Doctrine became an explicit instrument of U.S. interventionism. Theodore Roosevelt, president from 1901 to 1909, declared that “chronic wrongdoing, or an impotence which results in a general loosening of the ties of civilized society, may in America, as elsewhere, ultimately require intervention by some civilized nation, and in the Western Hemisphere, the United States’ adherence to the Monroe Doctrine may force the United States—however reluctantly—in flagrant cases of such wrongdoing or impotence, to exercise an international police power.” This corollary provided a moral justification for U.S. interventions, which were presented as civilizing missions rather than acts of imperialism. Between 1904 and 1934, the United States effectively exercised this role as an international police force, intervening militarily in several Latin American countries to protect U.S. economic interests, suppress revolutionary movements, or ensure the repayment of debts. This period, known as “dollar diplomacy,” profoundly shaped relations between the United States and Latin America, creating a legacy of mistrust and resentment that persists to this day.

I cannot help but draw a parallel between the Roosevelt Corollary of 1904 and the Donroe Doctrine of 2026. In both cases, moralizing language is used to justify what is fundamentally a projection of raw power. Roosevelt spoke of civilizing failing societies; Trump speaks of restoring democracy and justice. But deep down, what is the real objective? In both cases, it is about controlling the resources, markets, and strategic routes of the Western Hemisphere. What terrifies me is that Trump doesn’t even have Roosevelt’s intellectual subtlety to attempt to justify his actions with a semblance of moral theory. He simply says: we’re going to do it because we can, because we’re the strongest, and because it will be highly profitable for American companies. There is a brutality to this honesty that leaves me speechless. At least Roosevelt had the tact to pretend that it was a heavy moral burden he was reluctantly shouldering. Trump embraces interventionism with frightening candor, as if there were no moral, legal, or political constraints that could limit American action.
