"Raises the question: would you have supported the war anyway? If the intel said that Saddam really wasn't much of a threat to America and didn't show significant signs of becoming one? "

You are missing an important aspect of WMD. It's part of a cease-fire agreement. So the question is what are you going to do about this agreement? If Saddam complied with this agreement, I wouldn't support going to war with Saddam's Iraq. If Saddam had complied with this agreement, I would support ending at some point the No Fly Zone and lifting Sanctions- and lifting sanctions quickly because part of agreement is to repay Kuwait the money Iraq borrowed to fight Iran. And of course there is also returing remains of soldiers killed- both US and Kuwait.
The next problem is Saddam's constant hostility toward our airplanes in the No Fly Zone, his support of terror by paying the bombers families money, and his attempts at attacking the US- such as trying to kill a former US president.
What was needed from Saddam was a changed attitude- and as prospects of war became more likely- like say, at the beginning of 2003, a more dramatic demonstration that Saddan had changed his attitude. The best way Saddam could at least put off the possiblity of war was to make the UN inspectors at least *believe* they were getting full cooperation. "More cooperation" wasn't enough.
