Best Answer

The United States declared war on Germany (then, later, Austrian-Hungary) in 1917 for several reasons. The most important was Germany's unrestricted submarine warfare campaign, which led to the loss of American goods and lives despite America's neutral status. Also involved was growing American sympathy for the Allied cause and growing distrust of Germany, in particular.
