The reason why the United States join the world war is described below in brief details.

Explanation:

The U.S. entered World War I because Germany began a violent venture. Germany sank many American merchant vessels around the British Sea which provoked the American entrance into the war. Another reason was Germany's violation of its commitment to reject permitted submarine battle in the Mediterranean and the North Atlantic, as well as its efforts to attract Mexico into an agreement against the United States, as his intentions for declaring war.
