What did many Americans feel the US should do after the ship was sunk?

After the sinking of the Lusitania in 1915, many Americans felt that the United States should take a stronger stance against Germany and its unrestricted submarine warfare. The incident stirred public outrage and fueled anti-German sentiment, leading to increased calls for the U.S. to enter World War I. Some believed that the nation should prepare for war to protect American lives and interests, while others advocated for diplomatic solutions. Ultimately, the sinking contributed to shifting public opinion in favor of joining the conflict.
