What was the primary concern leading up to U.S. entry into World War I?

The primary concern leading up to U.S. entry into World War I indeed revolved around worries about maintaining economic partnerships. Prior to joining the conflict, the United States was heavily invested in trade with the Allies, particularly Britain and France. The unrestricted submarine warfare practiced by Germany threatened these economic interests, as American ships and trade routes were at risk.

The economic stakes were high, as American banks had loaned substantial amounts to the Allies, and a German victory could jeopardize these loans and economic stability. This interconnectedness of U.S. economic interests with those of the Allies elevated the urgency for the U.S. to respond to threats posed by Germany, resulting in a significant pivot from a position of neutrality to active involvement in the war.
