I just finished The Assassins' Gate: America in Iraq
by George Packer and found this passage near the end:
I came to believe that those in positions of highest responsibility for Iraq showed a carelessness about human life that amounted to criminal negligence. Swaddled in abstract ideas, convinced of there own righteousness, incapable of self-criticism, indifferent to accountability, they turned a difficult undertaking into a needlessly deadly one. When thing went wrong, they found other people to blame. The Iraq War was always winnable; it still is. For this very reason, the recklessness of its authors is all the harder to forgive.
