It is HIGHLY, highly likely, that if Chem/Bio weapons are not used by Iraq that it will take us 2-3 months to locate their labs/storehouses. Remember, in order to do that, we are probably going to have to locate some high level scientists (or govt officials - if we are unfortunate enough to have any of them remaining) and then interview them. As I suspect that such storehouses/labs are underground, it is very likely that there will be some major excavation which will have to be done to reach those facilities, as we are likely to have used bunkerbusters to bury the entrances under a hundred feet of rubble under the palaces, RG headquarters, etc. This excavation and search is going to take some time. Nevertheless, there is sufficient cause right now to realize that they have Chem/Bio - given the masks, suits, artillery shells, etc... as well as the trace finds of tabun, ricin, etc. already noted.
