On Wednesday, the Bush administration submitted a request to Congress for an additional $42.3 billion in war-related spending. That number comes on top of the $147 billion already requested by the Department of Defense and $3.7 billion for other agencies. The National Priorities Project has published an analysis of this amount, the majority of which will be spent on the Iraq War. The total $193 billion requested, an estimated $154.7 billion will be spent on the Iraq War. The organization estimates that $12.1 billion in tax dollars from Michigan have been spent on the war thus far, while the new amount would require another $4.1 billion in tax dollars from Michigan.

If this amount is appropriated without being reduced, the total cost of the Iraq War will be $611 billion. Compared to conflicts over the past fifty years, this would make the Iraq War the second most expensive conflict, just behind the Vietnam War's cost of $673 billion. As a way of comparison, the Korean War cost $470 billion and the Persian Gulf War costs $94 billion.
