Do you think the united states should have retained an isolationist stance

I think to a degree we should have. In WWII I think entering the war was necessary after Pearl Harbor, but nowadays I think we need to focus on America first, and stop worrying about every little thing in other countries. America has a lot of problems it needs to fix, and pulling out of other countries affairs would be a good way to do so.

no statements but ok.

the statement that best describes the idea of manifest destiny that was used in the 19th century would be that "it was fate that the united states would continue to  expand westward," since people thought the us was "destined" to do so.
