Iraq cost lots of money before 2001. One of these days, I'd really like to know how much it cost to enforce the no-fly zones and the UN sanctions in Iraq. I've forgotten how much it cost to take a DDG on a deployment (without considering personnel payroll and training) but I do know that we burned a lot of fuel. I suspect that the total bill (setting aside everything in this last year) is unbelievably huge, which is why we'll probably never know.
