What was one reason for U.S. involvement in World War I, as suggested by Wilson?

One reason for U.S. involvement in World War I, as articulated by President Woodrow Wilson, was the need to stop U-boat attacks on trading ships. The unrestricted submarine warfare employed by Germany posed a significant threat to American merchant vessels and the safety of its citizens. This aggressive tactic not only endangered American lives but also disrupted trade and commerce, which were vital to the economy and the war effort of the Allies.

Wilson's administration emphasized the importance of safeguarding American interests and ensuring the freedom of the seas. The sinking of ships like the Lusitania, which resulted in American casualties, intensified calls for action. This context illustrates that the protection of trade routes and maintenance of international maritime law were critical components of Wilson’s rationale for entering the war, highlighting a defensive motivation rather than imperial ambitions or revenge against Germany.
