Well, lets see, if we turn our back on the rest of the world and be stingy, we can pretty much expect the same treatment from them. America already has half the world hating it because of our abunance and freedom and the way we seem to take it for granted. Unlike JDM, I don't mind an argument on this stuff
I don't think it is our governments sole responsibility to do everything, but we do have way more resources that other countries, better technology and most americans do take pride in our role to help others. I really want to see the wealthy private sectors of the country help, they would collectively have the greatest impact. On another note, the things effecting other countries do also effect us. Consider the spread of disease into epidemic proportions, if we don't do anything about it, we could be hit really hard by it.
