Like Infanteer and others have said, the invasion is old news. There's no problem discussing something that has long past, but there really isn't anything new to discuss that hasn't already been brought up and chewed on by half the members of this board. Me included.
Basically, most folks fall in one of 3 categories:
1-GWB is the devil and a war criminal. The invasion is illegal. The UN should impose sanctions on the US. The elections are a farce. The UN is the one and only international body that can authorize military action in one country by another.
2-GWB is a great Pres, has prosecuted the war on terror superbly, and the world would be better if there were more like him. Saddam was the devil and any means to oust him from power is/was justified.The UN is a toothless, irrelavant, and corruption riddled organization who do way more harm than good.
3-The basis for war, while shaky now, was convincing and 'true' at the time. They didn't deceive us, and acted in good faith. Now that they are there, finish the job, and hand over power to locals.The elections are a good first step to rectifying the mistakes made.
Regardless of where you fall in those groups (some are a lttle of one, a little of another), we've heard all of the arguments....about ten times over.
If you want to discuss Iraq, perhaps we should discuss the more pressing and important issues relating to Iraq: the recent elections, rebuilding process, withdrawal of US/Western forces, security, conflict between the 3 main groups, etc.
