This is an anti-war website that tracks the cost of the wars. Both of them. Here's the number from about ten seconds ago:

Total Cost of Iraq and Afghanistan Wars since 2001:

$1,337,667,457,262

Look at that number. Eleven years of war. Fix it in your head. Now look at this one, taken from the White House budget documents:

Estimated Federal deficit for the fiscal year 2012:

$1,326,900,000,000.

Look at the one number.

Then look at the other. Back and forth. Notice any similarity?

Keep looking. Think hard. Ignore the sharp tang of ozone as current passes through dusty cerebral bus bars that haven't seen use in years.

A conclusion can be drawn here about the relation of the overall war costs to our current deficit situation.

Keep looking. Remember, 2012 is just one year. The deficit for 2011 was another $1.3 trillion. 2010, $1.29 trillion. The wars are winding down now and going out. But the estimated CBO accumulated deficits over the next ten years are $6.4 trillion.

I'm available for questions if it still isn't clear.
