Things That Make You Go "Hmm"

I suppose the the cost of any war is relative but here's a bit of context:

Annual cost of all sixteen U.N. peacekeeping missions currently underway : $3,870,000,000[United Nations Department of Peacekeeping Operations (N.Y.C.)]

Monthly cost of the U.S. occupation of Iraq :
$4,100,000,000[U.S. Department of Defense]

Revenue from Iraqi oil sales that the CPA could not account for, according to a 2005 audit : $8,800,000,000[Special Inspector General for Iraq Reconstruction (Arlington, Va.)] - from Harpers Index

That's a lot of zeroes.
