Explanation:

President Wilson had the idea of a security system empowered by a league of nations, where this league of nations would raise and army and defend the world from those who might want to invade or conquere soveraing states, this meant that US troops might be called to action to fight in this leage of nation army, which was something that the congress didn´t like, the Treaty of Versailles was rejected and never ratified by the United States which eventually, in 1921 signed peace with the German and Austrian-Hungarian governments.

when world war i broke out across europe in 1914, president woodrow wilson proclaimed the united states would remain neutral, and many americans supported this policy of nonintervention. however, public opinion about neutrality started to change after the sinking of the british ocean liner lusitania by a german u-boat in 1915; almost 2,000 people perished, including 128 americans. along with news of the zimmerman telegram threatening an alliance between germany and mexico, wilson asked congress for a declaration of war against germany. the u.s. officially entered the conflict on april 6, 1917.
