What are 3 reasons why the US would enter the war on april 6, 1917

Three reasons why the United States entered World War I:

• Germany's use of unrestricted submarine warfare.

• The sinking of the Lusitania

• The Zimmerman Telegram

~

Before World War I, Germany pledged to the United States that they would no longer use unrestricted submarine warfare. Although they knew it might trigger the United States into entering the war, they wanted to take the chance anyway. Numerous ships, including U.S. cargo ships were sunk, angering the United States.

The Lusitania was a cruise ship with over a thousand people on board, including Americans, Germany attacked the Lusitania using a u-boat. This angered many people, including civilians, who wanted Germany to pay for killing many people. Many people wanted the United States to join World War I after this, but President Woodrow Wilson was more of a pacifist who wanted peace and didn't want his country to join the war.

The Zimmerman Telegram was the final straw for President Woodrow Wilson and after this caused the United States to join World War I. Germany tried sending a telegram to Mexico, stating that if they attacked the United States, they would be promised American territories when Germany won the war. This was a major threat, so President Woodrow Wilson declared war on Germany.
