Answer:
Is this a question of a statement?
But yes during WWI the Russian army helped the allies (Serbia) and from a small little fight over land and leadership, each side called their allies and then those countries called others till it was a war that everyone but the US was involved in. The US said they were staying out but ended up selling supplies to everyone (mainly the allies) but the Germans got mad and they didn't want them helping the people they where fighting so they used a submarine and flipped over a supply boat. After that the US was determined to end the war and stop Austria/Hungary from doing anything else/ or any of the other aggressors (bad guys).
