Nobody?
Don't be so naive.
Well, obviously there are people who believe the earth is flat, in alien abduction, or in the Easter Bunny, etc. if you look hard enough for them.
Let's put it this way: can you name anyone of prominence, anyone at all, would in the media, politics, etc. who denied that Saddam had a nuclear project in 1991? Hans Blix certainly didn't deny, nor did Scott Ritter.
he is right. No one, at least no one I have heard of, has disputed that Iraq had a major nuclear weapons program until after the 1st Gulf War
what people disputed is if Hussein had an ongoing WMD program in 2002-2003
the fact that they retained technical knowledge is no surprise. this isn't a smoking gun
