I believe JumpCrisscross is suggesting that the World Food Programme winning the Nobel Prize is effectively the Nobel Foundation giving them 9m SEK to carry on their work (eg a grant) rather than awarding them the prize for the work they do to promote peace (eg a prize). I didn't read the comment as tongue in cheek at all. I read it as JumpCrisscross saying WFP didn't do enough to deserve the prize, presumably because tackling poverty and starvation isn't enough in JumpCrisscross's opinion.

That's precisely the reason why it was meant to be awarded for recent work/discoveries, and cannot be awarded posthumously. It is, and always has been, a grant program.
