Question

What were the main ideas for u.s. involment in world war 1

Answer 1

German U-boats sunk many American ships, the Zimmermann note, and the U.S. had strong economic ties with its allies.

Answer 2

The primary reasons that the U.S entered WW1 was for one, a German U Boat sank the Lusitania which had many Americans aboard even though it was a British ship, and because of the Zimmerman Telelgraph, a message sent to Mexico by Germany urging Mexico to declare war on the United States. The British intercepted this telegraph and told the U.S in order to convince them to join the war.
