I think a argument can be made that by helping less fortunate countries we can help our selves by decreasing their need for outside help. I realize that has been tried and failed in recent history to the point of insanity, but I think the theory is strong. If we can get (in this theoretical case) there EMS system up and functional then their will be less demand for our aid in the future. The next two choices are a little less popular, one take over the problematic country make it a providence and take all it's wealth for our own and restructure it in our image, two go back to the closed door policies of a earlier generation of our country.
