Yep, I remember that, and the inspections had a timeline that would have concluded in several months after the US invasion started. The US's allies were asking it to wait for those inspections to conclude.

Then, of course, the US ignored them because "he's going to hide the evidence", invaded for its own reasons... and famously found nothing. Blix was painted as an incompetent by the US, but even after stomping Iraq into dust and having full control of the country, the US found nothing.
