He believes in the "broke it, bought it" theory. Our actions caused their misery, we should do what we can to limit it.
That doesn't explain why he and his republican collegeagues were allergic to any kind of oversight and accountability, for the way our tax dollars were being spent in Iraq. There was virtually no meaningful oversight by the GOP congress, on iraq spending. My guess, is that enriching american contractors and protecting President Bush from criticism was more of a priority, than giving healthcare to some starving iraqi kid.
