On the first page of this thread you said:

"However, the USA's aid (in terms of percentage to their GDP) is the lowest of any industrialized nation in the world!"

   and

"USA only gave 0,11%"

   However, this number is only a partial accounting of the UN ODA funding. It is not the level of the "USA's aid" in total. Even if you choose to restrict your meaning to government funding. You have said this is a "proven fact." Where is it proven?
