How did America change ww1?

Answer 1

America's entry into World War I in 1917 significantly shifted the balance of power in favor of the Allies. The U.S. provided fresh troops, resources, and financial support, which boosted morale and helped replenish the exhausted Allied forces. Additionally, American involvement introduced new tactics and technologies that contributed to key victories, ultimately leading to the war's conclusion in 1918. The U.S. also played a crucial role in shaping the post-war peace process, influencing the Treaty of Versailles and establishing the League of Nations.
