In 2003 there were people who believed that Saddam was trying to acquire nuclear weapons, including some Clintonistas. I think that's why Joe Wilson and company made a major attack on Bush over the Niger yellowcake story (which didn't really disprove that Saddam was trying to acquire the bomb--not that the media was going to analyze the story objectively).
Whether Saddam would have managed to get the bomb if left in office, no one can know--but he would have been a lot closer to Israel than the Iranians are. He was causing trouble in a lot of other ways too. Whether there was a way to get rid of him without invading and trying to fix Iraq is another question--maybe not considering how long the Baathists had been in control in Iraq (ever since 1958).
