I'm going to leave out the 'WMD' factor out of the equation all together; it seems to have been a red herring (Deliberate or by mistake).
If you walk through your local park, and see a bully going round punching people about, what would you do? (Appart from going in there and trying to stop him yourself, which might well mean you would end up with two black eyes?)
You'd call the police, and tell them what's going on - some people would pretend not to notice, but I somehow think that forum members would be too ethical to do that.
Apply this to Iraq; namely Sadam. He was a dreadful tyrant, and someone should have done something about him a long time ago. I remember hearing some Iraqui sports men saying, that under his rule, if a sportsman did'nt do 'well enough', Saddam would have him executed.
The trouble is, that to some extent, if you are totally surrounded by violence and threat of your own life, the criminal fraternity tend to become ingrained with that same attitude towards life. When you get rid of the tyranic leader, alsorts of other ugly guys start crawling out of their hiding places, ready to step in his shoes.
So, in a way, this is a no win situation; get rid of Saddam, and now every crook with some ammunition wants a piece of the action. I bet that if all the 'allied troups' pulled out of Iraq today, there would be a few potential despot coming out of their holes, ready to fight all the others, for top place. Once there, what do you have? Hopefully not another Sadam, but a not 'very good' guy. I hate this negative way of thinking of mine, but I'm afraid that life has taught me to be cynical.
