Can't see the logic behind getting rid of WOMD during the run-up to the war.
If the idea was to flush 'em to avoid the invasion, seems like Saddam would have then been fairly forthcoming about it, otherwise what's the point?
If the idea is that Iraq hastily got rid of them once they realized they were being invaded, again, what's the point? Too late to make nice, can't really see it as a plan to come off clean after being invaded (unless you think Saddam had an amazingly baroque scheme to lure America into invading his country by dangling WOMD, then flush 'em to make America look really bad.?
Certainly seems more likely that if Saddam in fact had WOMD at the point of the invasion he would have used them.
Your argument would certainly apply if we were talking about a sane person, but we are not.
SH was paranoid and delusional.
