Answer: Isolation
Explanation:
When George Washington stepped down as President, he advised the nation to maintain a policy of isolation from the rest of the world especially Europe, so that the country could have a chance to grow without conflict.
The United States generally followed this policy up until 1898 when they got involved in a war with the Spanish that saw them win and acquire overseas territory in the Philippines and Puerto Rico.
The alliance between Great Britain, France, and the United States during WWII was called the Allies. If you're truly in High School; you should know this by now. But I'm not judging-so don't take it the wrong way.
