No. Its reason for joining the War is because the three ships that were, sank shot by Germany as they used the illegal power (unrestricted submarine warfare). Alvin Saptauli
Two actions that upset the Americans during World War I were Germany's unrestricted submarine warfare and the interception of the Zimmermann Telegram. The unrestricted submarine warfare led to the sinking of civilian and commercial ships, including the Lusitania, which resulted in American casualties. Meanwhile, the Zimmermann Telegram revealed Germany's proposal to Mexico to join the war against the U.S., further inflaming American public sentiment and prompting the U.S. to enter the conflict.
One significant effect of unrestricted German submarine attacks on shipping during World War I was the escalation of tensions between Germany and neutral countries, particularly the United States. The sinking of civilian and merchant ships, such as the Lusitania in 1915, resulted in loss of American lives and increased public outrage, ultimately contributing to the U.S. decision to enter the war in 1917. This strategy also strained Germany's resources, as they faced growing international condemnation and military opposition.
From what I can see, Germany's unrestricted submarine warfare policy, and the sinking of two american ships without warning is what motivated America to go into the war. Once again this is from what I can see on google lol.

Submarine warfare was abhorrent in the US during WW1. The British sank US ships trying to enter blockaded German ports. The same is true of US ships trying to enter blockaded British ports. However the Germans use submarine warfare to sink a USS Lusitania. That was the tipping for the US. Prior to then we were not wanting to get into "entangling alliances.
A Japanese float plane from a submarine carried out a flight over Sydney Harbour to map out the targets for the three midget submarines which carried out the attack.
