Would the United States remain outside the European war?

Without a war in the Pacific, would the United States have stayed out of the war in Europe?

The United States was already as involved in the European war as it could be without directly fighting. The answer points specifically to American financial support for Britain. The absence of a Pacific trigger would not restore a simple state of isolation. No date is offered for formal entry, but economic participation clearly preceded belligerency.
