hello flvs guy or girl lemme try to answer your question.

Explanation: The terms on which World War I ended set the stage for World War II, which began just 20 years later, by negatively impacting the belligerent countries politically, economically and socially.  hope this helps at all XD ;)

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.
