Why did americans feel closer ties to the allies?

America's ties with the allies were stronger than its ties with the Central Powers because many Americans still had ties to nations from which they had emigrated.

The main reason why America's ties with the Allies were stronger than the ties with the Central Powers was because of economic reasons. The Allies purchased large amounts of weapons and war goods from the United States. Germany was developing its own weapons thus it didn't enlist for American supplies.
