The year 1932, amidst the swirling currents of global economic despair and rising authoritarianism, found Cordell Hull, then a prominent voice within American politics, urging a profound reorientation for the United States. He declared that America must “gird itself, yield to the law of manifest destiny, and go forward as the supreme world factor economically and morally”. This statement was far more than a rhetorical flourish; it encapsulated Hull’s deeply held conviction that the nation’s future peace and prosperity hinged on an active, liberal internationalism, a vision he would steadfastly pursue as Franklin D. Roosevelt’s Secretary of State.
Hull’s journey to this sweeping pronouncement was rooted in a lifetime of political engagement and a unique economic philosophy. Beginning his career by campaigning with a horse and buggy, he rose through state politics to serve in Congress from 1906 to 1930. From his maiden address at age thirty-six, Hull passionately advocated for lower tariffs and fewer trade restrictions, believing that unhampered trade was intrinsically linked to peace and a higher standard of living for all nations. He saw tariffs and trade barriers as instruments that led to “economic misery” and left societies vulnerable to the siren call of dictators. For Hull, protectionism was a “defensive withdrawal” that ultimately harmed the very nation it purported to protect, famously stating that a “prohibitive protective tariff is a gun that recoils upon ourselves”.
His thinking evolved significantly after World War I, where he recognized the United States’ new economic preeminence as Europe’s creditor. He understood that for European nations to repay their debts and continue to purchase American goods, the U.S. had to lower its own import barriers. This perspective firmly positioned him as a “Wilsonian” internationalist, sharing Woodrow Wilson’s belief in an “open door to the world” for American enterprise, emphasizing “the righteous conquest of foreign markets”.
By 1932, the year of his powerful declaration, the world was reeling from the Great Depression, and Hull acutely perceived a dangerous ideological struggle unfolding globally. He observed “autocracy that is springing up in South America and throughout Europe, and even in the Orient,” envisioning a stark, worldwide conflict between “despotism and democracies”. In this precarious context, Hull believed the Democratic Party, and by extension the United States, had a “broader moral mandate” to foster a “revival” among “civilized nations”. This conviction underpinned his call for America to “gird itself” and become a “supreme world factor economically and morally,” a role he saw as a natural extension of an evolving “manifest destiny”. This was not a call for territorial conquest in the traditional sense, but for a pervasive economic and moral leadership that would shape global order.
Hull’s vision contrasted sharply with the “Mellonism” of the 1920s, which prioritized tax cuts and high tariffs that benefited the wealthy. He viewed the growing “fusion of corporate and state power” – what we might call corporatism – as a “fundamental threat to democracy”. For him, “suicidal economic nationalism” represented a dangerous path that directly contributed to international instability.
Once appointed Secretary of State under President Roosevelt, Hull set about implementing this vision. His “great achievement” was the Reciprocal Trade Agreements Act of 1934. This policy pursued bilateral trade agreements that incorporated “unconditional most favored nation (MFN) treatment,” aiming to lower trade barriers and expand global commerce, thereby boosting living standards worldwide. Hull, a shrewd politician, privately acknowledged that 95% of his program was “political or psychological,” designed to create a cooperative international environment.
He fiercely resisted internal opposition from New Deal “Brain Trusters” like Raymond Moley, who advocated domestic production controls and cartels over international trade liberalization. Hull’s steadfastness even led to Moley’s eventual departure, underscoring Hull’s significant political leverage.
Hull was also a vocal opponent of the autarkic economic policies pursued by Germany and Japan in the 1930s. He viewed their bilateral trade agreements and exchange controls as “aggressive” tactics designed to “undermine United States trading relations,” particularly in Latin America. He recognized that these protectionist and self-serving economic strategies directly fueled militarism and created an environment ripe for conflict. Crucially, he observed that “war did not break out between the United States and any country with which we had been able to negotiate a trade agreement,” and that the “political lineup follows the economic lineup”.
Even before the U.S. formally entered World War II, Hull’s influence helped define America’s economic war aims: dismantling the protectionist and nationalistic economic systems of the 1930s and establishing a new international order centered on the U.S. dollar, open markets, and reduced tariffs. This was indeed a form of “dollar imperialism” designed to project American economic influence globally. His efforts contributed significantly to the planning for post-war institutions like the International Monetary Fund (IMF) and the International Bank for Reconstruction and Development (IBRD), with the explicit goal of shifting the world’s “financial center… from London to the United States Treasury”.
Cordell Hull’s legacy lies in his profound redefinition of “manifest destiny,” transforming it from a concept of territorial expansion to one of economic and moral global leadership. He skillfully blended American idealism – the belief in freedom, democracy, and prosperity through trade – with the pragmatic pursuit of national self-interest. His work laid the groundwork for America’s post-World War II international economic system, a framework that, despite ongoing challenges from protectionist interests and congressional prerogatives, continues to shape global trade and diplomacy. His conviction that trade was a key to preventing conflict, even if at times overly optimistic, contributed a consequential and enduring idea to American foreign policy.
