I think what you will find is that a stunning amount of that "charity" falls within the giver's social circle. My understanding is it includes donations to the giver's own religious organization. Or even donating to a cause once it's touched you personally -- your mother dies of cancer so you donate to a cancer charity. Giving within your own monkeysphere, and being willfully ignorant of everything outside it, is what I am talking about.

As a spot check I googled "turkey earthquate donations by country". The result is a table with US on top donating $185M, followed by UAE donating $100M, Kuwait $68M, and finally the UN $50M.
