The largest reported donation to the WFP in 2008 was from the USA: $2,070,435,251, followed by Saudi: $503,546,083. Saudi gave about 1/4 of what the USA gave.

So let's not forget the all that the USA did for humanity.

Also, let's not forget that in Saudi there is no 'official mourning period' for the king. The flags don't fly at half mast. The country didn't have holidays to mark his passing. He was buried in a simple unmarked plot at his local cemetery, as per proper Islamic tradition.

Compare that to the elaborate grave for Sheikh Zayed in the UAE where his tomb has been built of gypsum (a sin) higher than two hands (a sin) and mourners visit his grave and recite the Koran.
