So the US decided to ship dollars to Iraq by the plane load as you do. Up to $2.4 billion per plane load, a total of $12 billion dollars, mostly in shrink wrapped bundles of $100 bills.
Now, why am I not surprised that $6.6 billion of that money has not been accounted for? Inquiries are under way and of course we get the usual public sector murmuring, foot shuffling, "desperate times" etc, but basically this is nothing more than grade A bumbling incompetence. Glad I am not a US tax payer.
