What was not the reason for the united states entering world war 1/7519483/dd2155f7? utm_source=registration

The US did not enter world war 1, because they believed that what happened in Europe stays in Europe, and although most people wanted to become part of the Allied Powers, there were some immigrants from the Central Power that wanted the US to be part of the Central Power. And so they stayed neutral until they had a real reason to join the war

hope this helps
