Starting from the premise that "it's morally wrong for the American government, instituted to protect American interests and American prosperity, to make that trade off", I don't see any reason to oppose imperialism.

I don't agree with the premise, but that's a separate point.

Right - but I am not asking whether you personally find imperialism as logical conclusion.

I am asking if you understand the difference between point A and B?
