Congressional analysts say the boost in troop levels in Iraq has increased the cost of war there and in Afghanistan to $12 billion a month.
All told, Congress has appropriated $610 billion in war-related money since Sept. 11, 2001. That's roughly the same amount that was spent on the war in Vietnam, taking inflation into account.
Iraq alone has cost $450 billion.
The figures come from the nonpartisan Congressional Research Service, which provides research and analysis to lawmakers.
For the 2007 budget year, CRS says, the $166 billion appropriated to the Pentagon represents a 40 percent increase over 2006.
If Congress approves President Bush's pending request for another $147 billion for the budget year starting October first, the total bill for the war on terror would reach more than three-quarters of a trillion dollars.
