Answer:
Separate from others.
Explanation:
The word "Isolated" in this context means "Separate from others." This is evident in the fact that the United States believed that due to the great distance across the Atlantic Ocean between the American continent and other continents such as Europe, Asia, and Africa, then they are separated from others.
Hence, in this case, the correct answer to the question is "Separate from others."
I think none of the above would be your answer.
