Don't forget statistics never show the amount of privately funded aid that US citizens give.  The 40% of international aid only includes the money from governments. Not included in the figures are money from charities, and food and supplies and etc aid.  If you include public and private aid given by US citizens, the total aid given world wide each year from the US would be between 60% and 80%, depending on the year. This also does not include the money used within the US itself.
