a moral or ethical comment? It is more of a fact, not what we "should" or "shouldn't" do.
When there are issues in other countries, who is there to provide resources and assistance? How many "third world" countries get tons of our help and then turn around and bitch about it?
My comment was that we can be completely self sufficient if we need to be. Believe it or not, but that bothers other nations. They simply can not state the same thing. They are more dependant upon others and us than they want to admit.
