What are three reasons the US decided to join World War 1?

Answer 1

The United States decided to enter World War I for various reasons, of which the following three may be considered most important: first, American public opinion had grown more favorable towards entering the war on the side of the western Allies. Second, German intrigue (especially in respect to the Americas) had become a source of great resentment and fear in America. Third, the sinking of American ships by German submarines had led to the loss of American goods and lives.

Answer 2

The US joined the Allies because Germany had violated U. S. neutrality by attacking International Shipping and then launched all out submarine warfare. The last straw was Germany sending the Zimmerman Telegram to Mexico.

Answer 3

Not a hundred percent sure but i would say...

1. Zimmerman's note

2. Sinking of the Lusitania

3. American nationalism and ego.

I would add that the Allies were in debt to the United States because of the war and if they lost, they wouldn't be able to pay the US back.

Answer 4

One reason was that Britain had to defend its ally, Belgium, who was being invaded by Germany

Answer 5

The sinking of the Lusitania is generally regarded as the event that finally brought the US into WW1, over a hundred American citizens died when the ship was sunk by the Germans.
