Question

Which countries had no imperialistic (empire-building) motives for entering World War II?

United States
Great Britain
Russia
Germany

Answer 1

True that the US had no imperialistic motives, but i think the same also applies to Great Britain. It does allow you to choose multiple answers.

Answer 2

I believe that the United States had no imperialistic motives for entering WWII. Because Great Britain, Russia, and Germany all used to be empires at some point in their history, and they might have wanted to become empires again, whereas America had no such wishes.
