* Fresh troops and supplies: America's entry brought nearly 2 million fresh troops to the Western Front, bolstering the Allied forces and helping to turn the tide of the war. The US also provided vast quantities of food, munitions, and other supplies to the Allies.
* Financial aid: The US provided significant financial aid to the Allied powers, particularly Great Britain and France. This financial support helped to keep the Allies in the war and ultimately contributed to their victory.
* Economic impact: The war stimulated the US economy, leading to increased industrial output and employment. The US also became a major creditor nation, as European countries borrowed heavily from the US to finance their war efforts.
* Political influence: The war gave the US a greater voice in international affairs. President Woodrow Wilson's Fourteen Points, which outlined a vision for a postwar world, had a significant impact on the peace negotiations and the shape of the post-war world.
Overall, America's involvement in World War 1 was a major factor in the Allied victory and had a profound impact on the global balance of power.
