Why did the United States enter World War I?

Accepted answers:

  • Because Germany attacked U.S. civilian ships
  • To support the Allied Powers (England, France, Italy, and Russia)
  • To oppose the Central Powers (Germany, Austria-Hungary, the Ottoman Empire, and Bulgaria)

Why this is the correct answer

America initially tried to stay neutral as World War I raged in Europe. German submarine warfare targeting civilian ships, including vessels carrying American passengers, combined with the desire to support Allied nations like Britain and France, ultimately pushed Congress to declare war in April 1917.
