"Would it be nuts to think the jihadi's would use the flu
as a bio weapon?"
Yeah, I think it might be a little nutty to think they have weaponized flu or even the natural H5N1 or a weaponized 1918 version but I don't think it is nutty to be concerned about North Korea, Iran, Cuba or any Banana Republic with sectors under Chinese or Russian control using any form of any WMD in opportune manner.
This whole flu scare is to drum up sales for the drug companies...they are sold out of flu medicine til 2007 now...
