Why was Georges Clemenceau pleased by the United States entering World War I?

Georges Clemenceau was deeply concerned about the United States' attitude toward World War I and had sent urgent appeals to the American public and President Woodrow Wilson to join the conflict.1

When the United States finally entered the war in April 1917, Clemenceau was overjoyed. His reaction was rooted in his intense focus on achieving victory for France; he was a staunch patriot who believed in a "fight to the finish" against Germany and sought to create an indomitable "will to victory" among the French people. By 1917, France faced significant challenges, including war-weariness, low morale, and serious military mutinies, leading to widespread defeatism. The addition of American support was a critical boost to the Allied war effort, providing both military reinforcement and the hope of economic solidarity that Clemenceau and his government viewed as essential to sustaining the struggle against German aggression.123
