The Franco-Prussian War was not directly related to the entry of the US into World War I.
The immediate cause of American entry into World War 1 was the German submarine warfare that targeted American ships. In addition, the interception and publication of the infamous Zimmermann Telegram, in which Germany proposed a military alliance with Mexico against the United States, further pushed the U.S. to join the war. American entry ultimately tipped the balance in favor of the Allies and led to their victory. Additionally, it accelerated social and political changes in the United States, as well as increased American influence on the world stage.
While the numerous causes are complex and convoluted, the basic root cause was World War I and the inequity with which Germany was treated at the close.
