Answer:
stay neutral, not taking sides.
Step-by-step explanation:
In the beginning, the United States wanted nothing to do with European conflicts.
The murder of Prince Franz Ferdinand started WWI. United States stayed out of it -- declaring it to be a European Problem..
The straw that broke the camel's back came in the form of Germany's determined efforts to use submarines to sink passenger ships. In 1915 the Arabic and the Lusitania were both sunk, and that enraged Wilson, it was not enough to push him to war. But it was enough to use later, when Germany issued a private note urging Mexico to declare war on The United States to get their (Mexico's) land back.
