re: All a matter of time for the inspections and the burden of proof
If the burden of proof was for Saddam to show he had no WMD, how could he show it when he didn't know where any of the very old few leftovers (from before GW1) were?
BTW, sending inspectors to Iraq (which was required by 1441) meant that they had to proove Saddam had those WMDs.
The inspectors were not presented the inexistent WMDs, they went after them. Or tried to and with insistance, the Iraqis did allow them ( not all the time , everywhere, but much more openly than before).
