The dithering in the Security Council has nothing to do with Saddam or Iraq per se, but rather about the consequences of removing him, and how to contain and manage the regional chaos that will certainly ensue.
Problem is, we want the destabilization, because that's the only practical way to defuse the slide toward Islamism in the Middle East. And in particular that's the only way to upset the logistics (recruiting, communications, money) of the Islamists, which are partly dependent upon tacit state sponsorship by Iran, Iraq, Saudi, and Pakistan.
This is only tangentially about Saddam.
