Answer:
The agreement that all nations in the League of nations would be rendered equal.
Explanation:
Article X called for the assistance of the members of the League when one of them experienced external aggression. It was signed by France and Britain but U.S. president Woodrow Wilson could not ratify it because of a strong objection of the Congress.
The U.S. Congress opposed to the article because it involved the power to make war without their aprobal. The Senate believed it was best not to involve in international conflicts and as the Constitution states the president couldn´t ratify a treaty unless the senate gives it consent.
