Suave - to finish the quote which you cut off mid-sentence:
"But they also knew that any such move would set off alarms at the International Atomic Energy Agency, which monitored Iraq's use of uranium, and that Iraq would be stopped from developing any more enriched uranium. Thus, Iraq would be able to build only one oversize bomb. Informed of this, Hamza says, Saddam agreed to shift to concentrating on using chemical and biological weaponry to halt the allied forces of Desert Storm."
So, contrary to the point you're trying to make, this doesn't support the idea of any Iraq nuclear weapons program post-'91. In fact it doesn't support *anything* post-'91.
Regarding the "immediate threat" case for war - Bush et al clearly argued it:
(Sept. 2002) "Last month, Bush told reporters that an International Atomic Energy Agency (IAEA) study had concluded Iraqi dictator Saddam Hussein was "six months" away from obtaining nuclear capabilities. "I don't know what more evidence we need," concluded Bush. Yet the IAEA never issued any such report with those findings about Iraq.
Condoleezza Rice warned that Saddam might unleash a "mushroom cloud," and Defense Secretary Donald Rumsfeld suggested Saddam might soon attack America and kill "tens of thousands of innocent men, women and children."
Ladies... this wasn't *that* long ago.... If you've got the inclination and about 2 minutes you would come up with hundreds of quotes/examples.
