Concept note-1: -The United States later declared war on German ally Austria-Hungary on December 7, 1917. Germany’s resumption of submarine attacks on passenger and merchant ships in 1917 became the primary motivation behind Wilson’s decision to lead the United States into World War I.
Concept note-2: -Individual Americans supported one side or the other, although the majority were sympathetic to the Allies. Many contributed to relief efforts; others volunteered as ambulance drivers or nurses, or even as pilots and soldiers.
Concept note-3: -Woodrow Wilson, Washington D.C. In early 1917 much of the American popular sentiment against participation in the war began to change with the increase of German submarines targeting even U.S. civilian ships sailing in the Atlantic.
Concept note-4: -But the neutral USA entered World War II only after many months of argument in Congress and among the general public, and only when a Japanese fleet launched a big surprise air raid against its Pacific naval base at Pearl Harbor in Hawaii on 7 December 1941.
