Well, isn't it obvious that the U.N. usually plays both sides against the middle? The U.N. resolution was watered down to allow wiggle room and the interminable delay in enforcement. This type of obfuscation is a hallmark of all bureaucratic organizations. "Let's give everyone a little bit of what they want, and nothing will change." The difference is that this time, someone called them on it. Whether it was right or wrong is a matter of opinion, but the U.N. most certianly didn't bank on us taking action.
As far as the Bush team was concerned, I've already stated that I think they were overly optimistic in interpreting intel. Do I think they lied outright? No. Do I think certain members extrapolated conclusions from incomplete intel and sold it as solid info. Yes, I do. Is that wrong? Of course. I'm not happy about it, either.
But also remember that there were plenty of "experts," including U.N. weapons inspectors, who believed that Saddam was hiding WMD. Plus his evasiveness certainly only added fuel to the fire.
But, to insist, as some do, that the administration knew that they would find no WMD, seems to me an error in logic. Would they invite all of this scrutiny and embarrassment upon the Bush adminsitration and the nation as a whole by knowingly invading a country under false pretenses and then have to admit that they were wrong? Or worse, that they lied. For what reason? Please don't give me the "war for oil" argument (I know you're smarter than that). I find that whole line of thinking simple-minded and ridiculous. If we were only interested in oil we would have been playing ball with Saddam, not trying to remove him. It would have been a hell of a lot cheaper, too.
Believe it or not, I, like you, happen to think both parties suck. Government is way too big and the American public is being duped into thinking that more government is better. When you look at the facts, more government is usually a disaster.
The U.N.? Well, I think it's next to useless. The only thing it does reasonably well is provide humanitarian aid. How anyone can think that a world organization with democratic values can work when many of the member nations are ruled by thugs is beyond me.
Anyway, on a related note, read John Stossel's book, Give Me a Break, if you haven't already. It's no literary masterpiece, but you'll love it. It will also make you very mad.
