I have not read everything here, but there are many MANY reasons to neutralize Saddam. Do you people not realize his sons are more crazed than he is? Read the Sports Illustrated article on Uday Hussein and you will know. Saddam Hussein does have the power to kill the world three times over, also. In 1995, they declared to the UN that they produced 5,000 gallons of Botulinum toxin, the deadliest substance on earth. 1 gram of it can kill 1million people (go look it up, it is true). There was no sign they got rid of it, and inspectors themselves acknowledge he still can produce much more than that. If they don't neutralize him now, his sons will take over eventually and are more willing to use them. I can also see why people are against it, though people usually are against any war that takes place.
I would have to say that most of the world is opposed to it because of Bush's own diplomatic shortcomings, and comparisons to how Clinton managed to gain support for Kosovo can probably prove that. Arab nations DO want Saddam out, and he has already launched 3 missiles at Iran (they confirmed it was not US, but Iraqi), not to mention the 10+ at Kuwait. Most of the statements made by their leaders are for domestic consumption, because their governments don't want them to be even more angry.
To say that inspections should have run their course is not an intelligent argument against war is not intelligent. Inspections were working and, like I said, it was evident Bush was determined to go to war. If he let them run their course it would have been better for him. I doubt the whole oil argument, because it is so evident that he is finishing what his dad started. On drudgereport.com, I saw a link to a news article quoting Bush in March 2002 as saying "F--k Saddam." I think that says enough right there about the reasons. However you cannot deny that getting him out of there is best, but they did a sloppy job of drumming up support. So sloppy that he has turned most of the world against us (though most of their citizens are being as childish as ours--see recent reports of European consumers boycotting American companies that are locally owned franchises...how stupid). It is a very sticky situation, but could we please refrain from lowering ourselves to insults? Please keep the arguments professional and acknowledge that everyone is entitled to their own opinions. If you cannot contain your anger then go sit in the corner for timeout lol

Last but not least, look at France, Germany and Russia. They do not do this for the good of the world all the time either. I suppose we should mention China, and how they laid the Fiber Optic cable for Iraq's air defenses. Lets not forget about all that France, Germany, and Russia have done for Iraq. They are probably as guilty about following dollar signs as we are, and probably are afraid that they won't get their debts paid if Saddam Hussein is toppled. We put him in there a long time ago, and gave him aid to invade Iran after their revolution too. The world caused this problem, and its a shame the world isn't dealing with it on a united front. I am an American, and I hate our seemingly unconditional support of Israel. The fact that we vetoed resolutions on condemning the deaths of UN staff and personnel by the Israeli Military is outrageous. These are my 2 cents on the matter, and I would again like to urge intelligent discussions, and not to lower yourselves to insults of one another.
