Consider all that we've been through in the last few years. We had 9/11 and then have fought two wars. We had...well, I lost count on how many hurricanes we had. We've had as much death and destruction as any country, any people on the planet, yet we still find it within ourselves to contribute money, manpower(person power?), etc. to the victims of the tsunami, in addition to the aid we normally contribute world wide. And you know, if any country, even those who profess to hate us, were to ask for help, we'd be there.
We are a good, kind and decent people and we don't need acknowledgment to do the right thing. No good deed goes unpunished, but that doesn't stop us from doing the right thing.
I think the American people are very generous, to a fault....
I bet our private giving would dwarf most countries...
