I find a couple of things a little hard to swallow from that article.
First off, Richard Perle was informed and Perle went back to Washington to discuss it but was rebuffed by the hawks.

Wasn't Perle one of the the leading "hawks"? If he really was interested in investigating this angle and found it credible, what "hawks" would have been more hawkish than him?

Mr. Obeidi told Mr. Hage that Iraq would make deals to avoid war, including helping in the Mideast peace process. "He said, if this is about oil, we will talk about U.S. oil concessions," Mr. Hage recalled. "If it is about the peace process, then we can talk. If this is about weapons of mass destruction, let the Americans send over their people. There are no weapons of mass destruction."
Mr. Obeidi said the "Americans could send 2,000 F.B.I. agents to look wherever they wanted," Mr. Hage recalled.
I think we were quite clear that inspectors were not the answer. A complete and full accounting of the WMDs and other banned weapons was needed. publicly, not in some back door deal...

He said that when he told Mr. Obeidi that the United States seemed adamant that Saddam Hussein give up power, Mr. Obeidi bristled, saying that would be capitulation. But later, Mr. Hage recounted, Mr. Obeidi said Iraq could agree to hold elections within the next two years.
Wasn't Saddam just re-elected in 2002? By a 100% vote with a 100% voter turnout?
QUOTE
According to some official reports, Saddam appeared to have enjoyed great popularity within Iraq. A 2002 referendum, asking whether he should continue to lead Iraq, claimed 100% of voters thought he should, and that the turnout was 100%, with international media releasing pictures of Iraqi women voting in their own blood. However, he was the only presidential candidate on the ballot and voting was mandatory.
Encyclopedia: Saddam HusseinOf course, THIS time an election would have been legitimate....
Saddam was a known liar, cheat, and deception artist. There was no reason to trust him in some back door deal.
