Great line of the day

From Attytood via Today in Iraq:

. . . it all gets intellectually tangled when you try to compare a one-day terrorist attack, which deliberately targeted civilians in a way that any civilized human should find repulsive, with three and a half years of combat and collateral damage.
Tangled -- and yet I do believe in my gut that the killing fields in Iraq flow directly from the senseless violence of 9/11, and so I believe that stories and blog posts that compare the death tolls are worthwhile -- because for one day they make us think, a little harder and a little more out loud than usual, what Americans should be thinking every single day.
Just what in God's name are we doing over there?

Emphasis mine.
