You have to have some real baseline for what giving even means.
Dropping bombs on people is not generally considered giving.
Giving bombs to other people to drop on other people is not generally considered giving.
And that is just the broad measure of phoney "giving" at the Federal Govt. Level
Is "giving" expired medicines to third world countries -- to avoid disposing of them as bio-hazard / waste by US corporations "giving?"
When Illegal Aliens in the US send money back to their home country is that foreign aid or "giving" by private remits?
When grants are written to allow the purchase only of certain US corporate products is that "giving?"
And then there is the wide spread between the talk about giving and the walk of what is actually given . . . that is just scratched upon here >>>
US and Foreign Aid Assistance - Global Issues
Not saying their numbers are correct, but they list these countries above US:
Sweden
Denmark
Netherlands
Norway
France
Belgium
Switzerland
Finland
United Kingdom
Austria
Germany
Canada
Ireland
Australia
Italy
Portugal
Japan
Greece
Spain
But I would think any true numbers would have to back out military, and hinky corporate deals before you could even begin to get to the truth of the matter.
