aelman: We are a nation of heroes, and we prove that every time a natural or man-made disaster hits in our country. But that's the problem: in our country.
Actually, the US has sent volunteers, financial assistance and medical supplies to the site of nearly every major natural or man-made disaster in the world over the past 60 years. When is the last time you have heard of another country sending financial or human assistance to the US? The US has also interceded in many world conflicts that might have otherwise ended in genocide. I won't try to say the US hasn't done bad things in the world, but I don't think the balance sheet is nearly as one-sided as some people try to imply.
I won't bother to answer most of the other stuff posted here recently.
