Question: why did the united states get involved in the war?
Answer: Now, up until just before the U.S. declared war on April 6th, 1917, the U.S. had desperately tried to stay neutral, but ties to Britain, propaganda, the sinking of ships by German U-boats, and a German attempt in the Zimmermann Note to get Mexico to declare war on the U.S. pushed the U.S. to getting involved.
