The correct answer is D) American citizens wanted to stay neutral until innocent Americans were killed.
The statement that best describes the events leading up the United States' involvement in World War I is "American citizens wanted to stay neutral until innocent Americans were killed."
We are talking about the sinking of the Lusitania ship by the German Navy.
President Woodrow Wilson tried to maintain the neutral foreign policy on the issue of the war in Europe. But the sinking of the Lusitania and the interception of the Zimmerman telegram, in which the government of Germany asked Mexico for help in the war, made President Wilson to ask Congress for a war declaration against Germany. Finally, the United States entered World War I on April 6, 1917.
