19.10.4 United States and the First World War

At the turn of the 20th century, the United States adhered to a strict policy of neutrality. Yet, by 1917, a series of provocations and economic entanglements propelled the country into the tumult of the First World War. This transition would redefine both the nation's international role and its relationships within the Americas.

Trajectory from Neutrality to Active Participation

  • Philosophy of Neutrality: President Woodrow Wilson and the American public initially espoused neutrality, reflecting a tradition of isolationism that sought to keep the United States clear of European entanglements and wars.
  • Economic Ties: Despite its neutral stance, the United States formed strong economic bonds with the Allied powers, primarily through extensive trade and loans. This relationship effectively tethered American economic prosperity to the success of the Allies, particularly Great Britain and France.
  • Submarine Warfare: The German practice of unrestricted submarine warfare, which sought to blockade the British Isles, increasingly threatened American ships and civilians. The sinking of the RMS Lusitania, with 128 American passengers among the dead, ignited public outrage and began to turn the tide of American sentiment against Germany.
  • The Zimmermann Telegram: The Zimmermann Telegram, intercepted and decoded by British cryptographers, was a secret diplomatic communication from Germany to Mexico proposing a military alliance against the United States. Its publication in March 1917 galvanized the American public and politicians alike against Germany, bolstering the case for entry into the war.

Reasons for United States' Entry into the War

  • Economic Imperatives: The U.S. economy had become significantly intertwined with that of the Allies. The security of loans and trade became a compelling reason for safeguarding Allied interests, indirectly implicating American economic stability in the success of the Allied campaign.
  • Ideological Stance: President Wilson depicted America’s entry into the war as a principled stand for democracy and liberty. This framing aligned with the broader trend of American exceptionalism, casting the United States as a beacon of freedom and moral righteousness on the global stage.
  • Internal Pressures: The lobbying efforts of arms manufacturers and bankers, who had a vested economic interest in an Allied victory, also played a role in pushing the United States towards war.

President Wilson's Peace Ideals

  • The Fourteen Points: In January 1918, Wilson articulated his vision for a post-war world order in a speech to Congress, laying out the Fourteen Points. These included the removal of trade barriers, reduction of armaments, and the right of national self-determination. Most notably, the Points proposed the creation of a League of Nations to safeguard peace and prevent future conflicts.
  • Advocacy for Moral Diplomacy: Wilson’s diplomatic principles were rooted in morality rather than strategic interests. He believed that the United States had a duty to spread democracy and peace, rather than conquer and subdue.

Struggle for Ratification of the Treaty of Versailles

  • Congressional Resistance: The Treaty of Versailles incorporated Wilson's proposal for a League of Nations. However, significant opposition within the U.S. Senate, led by figures such as Henry Cabot Lodge, worried that membership in the League would compromise U.S. sovereignty and commit American forces to conflicts without Congressional approval.
  • National Debate: The battle over ratification spilled into a national debate over the United States' role in the world. While some advocated for an active role in shaping international peace, others feared the consequences of entangling alliances.
  • Outcome of Ratification: The Senate ultimately rejected the Treaty of Versailles. As a result, the United States signed separate peace treaties with the Central Powers and did not join the League of Nations, signalling a retreat to isolationism in some aspects of foreign policy.

Significance for the Country's Hemispheric Status

  • Foreign Policy Reorientation: The experience of World War I marked a fundamental reorientation in U.S. foreign policy, with increased international engagement, yet with a wary approach to international alliances and commitments.
  • Ascendancy to Power: The post-war period saw the United States emerge as an economic and military power. This ascendancy had profound implications for its hemispheric role, as the nation began to assert its dominance and influence in the Western Hemisphere more vigorously.
  • Regional Implications: The United States' involvement in the war and its economic boom thereafter affected other countries in the Americas. The U.S.'s foreign policies during this era, including interventions in Latin America, were justified through the Monroe Doctrine’s Roosevelt Corollary, indicating a shift towards a more interventionist stance in the region.

In summary, the United States’ path to involvement in the First World War was shaped by a convergence of economic interests, ideological commitments, and geopolitical provocations. President Wilson's vision of a world made safe for democracy and his Fourteen Points speech were instrumental in defining the United States' new role on the world stage. The subsequent struggle with the Treaty of Versailles underscored the nation's ambivalence about international engagement, setting the stage for future foreign policy debates. This period was a crucible in which the modern American stance of international involvement, tempered by a cautious view of global commitments, was forged. The ramifications of this stance echoed throughout the Americas, as the United States began to wield its increased power in shaping regional dynamics.

FAQ

Wilson's 'Fourteen Points' addressed the issue of colonialism and self-determination by advocating for the interests of the colonial populations in the peace negotiations. Point five explicitly suggested that colonial claims should be handled with the interests of the populations in question being given equal weight as those of the government. This was a challenge to the traditional colonial powers, which typically prioritised their own strategic and economic interests. The Points also called for transparent agreements, and point twelve demanded the Turkish portions of the current Ottoman Empire be assured a secure sovereignty, while the other nationalities under Turkish rule should be given the opportunity for autonomous development, highlighting the principle of self-determination. While the implementation of these ideas was limited in the final peace settlement, they did lay the groundwork for future movements for decolonisation and national sovereignty.

Economic factors played a nuanced role in the U.S. Senate's rejection of the Treaty of Versailles. Post-war economic concerns centred on the ability of European countries to repay their substantial debts to American banks. Some Senators feared that the financial obligations imposed on Germany by the Treaty would destabilise the German economy and, by extension, impede its ability to repay debts, which would negatively impact the American economy. Moreover, there was an economic desire to return to pre-war trade conditions, which some believed the League of Nations could compromise by entangling the U.S. in future European conflicts. Additionally, isolationist sentiment in the Senate was partly driven by concerns that international economic entanglements might lead to increased foreign competition and economic instability at home.

The sinking of the RMS Lusitania on May 7, 1915, by a German U-boat was a pivotal event in the lead-up to the United States' entry into World War I. The loss of 1,198 lives, including 128 Americans, on what was perceived as a civilian vessel, sparked outrage both within the U.S. and internationally. It shattered the German assumption that such actions would not provoke the U.S. into abandoning its neutrality. This event was leveraged by pro-war advocates to rally public opinion against Germany, contributing to the erosion of the neutral stance many Americans held. While it did not immediately lead to U.S. entry into the war, it marked a significant step towards the eventual involvement, as it increased anti-German sentiment and raised serious questions about the morality of Germany's wartime tactics.

U.S. involvement in World War I had a substantial impact on its relationship with Latin America. During the war, the United States increased its economic and political influence in the region, in part to secure resources for the war effort and to prevent European powers from gaining a foothold in the Americas. This period saw increased U.S. investment and intervention in Latin American countries. The war also served to highlight the United States' Monroe Doctrine, with its corollary of U.S. hemispheric hegemony, as the country sought to exclude European interference. While the U.S. projected itself as a proponent of democracy and self-determination on the world stage, its actions in Latin America were often more self-serving, prioritising strategic and economic interests, which led to a legacy of mistrust and complex relations with its southern neighbours.

The shift in American public opinion from isolationism to support for the war effort was gradual and occurred over several years. Initially, the sentiment of the American public was strongly in favour of neutrality, influenced by the horrors of trench warfare and a desire to avoid European conflicts. However, a series of events, including the sinking of the Lusitania, which resulted in the loss of American lives, and the interception of the Zimmermann Telegram, which suggested a direct threat to American security, gradually swayed public opinion. Propaganda campaigns by the government and pro-Allied groups also played a crucial role, highlighting the threat posed by German militarism and appealing to American patriotism and moral principles. By portraying the conflict as a battle for democracy and freedom, the Wilson administration effectively mobilised public sentiment towards supporting American intervention.

Practice Questions

Evaluate the extent to which the economic interests of the United States influenced its decision to enter the First World War.

The economic interests of the United States played a significant role in its decision to enter the First World War. The substantial loans provided to the Allies had entangled the U.S. economy with their success. The protection of trade routes, particularly with Britain and France, was paramount as unrestricted submarine warfare threatened U.S. shipping and, by extension, its economy. An excellent student would argue that while ideological reasons were publicly foregrounded, the underlying economic interests were a crucial, determining factor for war entry, highlighting the intertwining of moral ideals with economic pragmatism in foreign policy decisions.

Discuss the impact of President Wilson's Fourteen Points on the post-war world order.

President Wilson's Fourteen Points had an aspirational impact on the post-war world order, proposing principles like self-determination, free trade, and the establishment of a League of Nations. Although the Fourteen Points were only partially adopted in the Treaty of Versailles, the League of Nations was formed, embodying Wilson's vision for collective security. An excellent student would note that while the U.S. Senate's rejection of the Treaty and the League indicated a return to isolationism domestically, the Points did inspire movements for self-determination and international cooperation globally, shaping the diplomatic landscape of the 20th century.
