Immoral Start Begets Immoral Mess
At the core of the problem with our Iraq policy is that this putatively "Christian" president utterly ignored centuries of thought and writings in the Christian tradition about what does or does not constitute a "just war."
Is the use of force taken as the last resort? Is it a defensive war? Is there a reasonable chance of success? Is the amount of force roughly proportional to the provocation? Finally, and most important, have provisions been made, as much as possible, to shield civilians from being collateral damage?
Despite the labored efforts of such neoconservative theorists as Jean Bethke Elshtain and George Weigel, the invasion of Iraq meets none of these criteria. (Elshtain, for example, totally ignores such crucial bits of evidence as the Downing Street memorandum in constructing her justification for war in Iraq.)
