Describe two major reasons for us entry into wwI

1. Germany kept on attacking passing merchant ships and passenger ships with submarines.

2. Germany wanted to be in an alliance with Mexico, which made the U.S. worry they were going to be attacked.

this means that germany had to pay the allied countries. reparations are/is essentially payment for something that they have done wrong, so after ww1, germany was forced to pay reparations so they could replenish the allied countries resources' that they had lost during the war.
