Every nation deserves the government it harbors, whether a benevolent democracy or a ruthless dictatorship. If they hated Saddam so much, they should have gotten rid of him themselves, or at the very least carried the bulk of the burden for doing so.
If and only if Saddam became a viable threat to the US, should we have gone in there and flattened him. And instead of staying around to turn Iraq into the America-loving, Walmart shopping, McDonald's-eating paradise that it will never be, we should have treated Iraq as an enemy, not an confused, mis-led ally-to be.
That 300 billion would have been better off in the hands of R and D departments of 100 high-tech firms so that in another decade, we can finally end our dependance on the Arab world and let them shrivel back into the sands from which they arose.
And our service men and women, who are all too often used as the rallying cry for thoughtless, largely useless military operations, are better off alive and at home.
