Just seen Kendall's question. Can't check for sure right now, but I think they were there 1991-98. Again going from memory, I think they carried out about 500 inspections, of which about ten were interfered with in any way - and then only postponed, not refused. If any of this turns out to be wildly wrong when I've checked, I'll do a correction.

From what Ritter has been saying in interviews, it seems he is sympathetic to the Iraqi view that some of the disputed inspections sought to go too far into Iraqi state security, and therefore way beyond the brief.
