Another way of looking at:
Taxpayers pay 73 cents a gallon for the war (which I though was't 'bout the oil).
Back of the envelope calc:
Cost of Iraq war, per year: from here
2 billion a week is ~ 286 million a day.
From here, in 2006, 388.6 million gallons/day of gas were used by the US.
286 million dollars / 388.6 million gallons = $0.73 dollars per gallon
However, if only 3 % of that gasoline comes from Iraq, then it becomes 286 / 11.7 = 24 dollars per Iraq gallon.
I'd like to see how you came up with your calculation of $9.75 a gallon.
