It is important to note that the shell was a binary delivery system. UNSCOM supposedly accounted for all that existed in Iraq (circa of construction, the mid to late 90's), but AT LEAST one escaped the Ritter smoke screens. The construction time is the essential point ... if produced during the clinton administration period, this is evidence of an ongoing WMD program that had to be stopped!
Note that we had no clue, until Saddam's son-in-law defected and told us about it. He also told us about other chem and biological weapons developments, which the media and even the intel community called in question. This find also proves that he told us the truth about this and most likely about the other stuff too.
"Iraq's first field-test of a binary-type shell containing sarin was in 1988, U.S. defense officials have noted. Saddam's government only disclosed that it was testing and producing sarin after Iraqi weapons chief Lt. Gen. Hussein Kamel al-Majid, Saddam's son-in-law, defected in 1995. But Iraq never declared any sarin or shells filled with sarin remained. "
