Says who?
Says anyone with common sense. Enriched uranium which could be used to build a nuke or dirty bomb getting into the hands of terrorists is a bigger danger than yellowcake in the hands of even a madman like Saddam who couldn't enrich it without it being noticed.
Even if I believed this guy that there were actually 800 incidents and that those materials were any real danger, that was over the last 20 years. Would it have actually taken over 20 years for this stuff to be weaponized and used? Smells like a mostly bull**** article to me.
It's not all being stolen by the same person you know!

The point was that if 800 incidents have occurred and nothing much was done about them then there are likely to be 800 more. And it only takes one of those incidents resulting in the wrong people ending up with fissile material for the world to be introduced to nuclear terrorism.
I consider that a credible threat. If you don't then I really don't know what to say to you that could convince you.
And spend that money on what? Invading friendly countries who have no desire to create or acquire WMDs? You don't use the military to FIND WMDs. That's what the CIA is for.
And with that sentence you not only pointed out that you couldn't be bothered to read the article before saying it was wrong but also undermined your own argument.
You spend the money where the $150m in my original quote was spent. Security for existing nuclear sites, removing and reprocessing material from countries which no longer have a use for them (like Bulgaria). It's all in the article.
Spending $648bn to allow the military to look for WMD in Iraq even though they didn't exist is stupid. As you yourself said you don't use the military for that. That is what the CIA is for. Not to mention UNMOVIC.
Sorry, but according to all the intelligence reports at the time, Saddam was the #1 threat concerning WMDs (along with many many many other non-WMD threats) at the time. Unstable dictator + large amount of funds + desire to obtain WMDs + record of extreme violence + many other extremely troubling things = bad news.
Funny how you forget that you had Hans Blix practically screaming that he either didn't have WMD or was acting to dispose of any means he had to deliver them though. Funny how they've found no proof of WMD or means of producing them. You can try to claim that you only know that in hindsight but that's bollocks. We knew at the time that he didn't have them.
Oh, by the way, Saddam DID have extensive ties to terrorists, and it is entirely possible that he would have supplied them with uranium (see: http://online.wsj.com/article/SB120631495290958169.html?mod=opinion_main_review_and_outlooks )
And as I keep saying he didn't have anything much to supply them with. He had no weaponised uranium.
President Bush's reasons aside, the invasion of Iraq was backed by the U.S. senate and the UN almost unanimously.

The UN
backed the war in Iraq? Oh that is just too ****ing funny for words. Tell me you meant US.
