yes, it could do a lot of damage if it was radiological or something, some of you guys stress the panic level that a bio attack would be and so true, we've never seen that happen, so is it activated or something?
See, a good bio-attack isn't quite as sure a thing as say a nerve gas or nuclear attack. It takes some time for a great epidemic to spool up. There are a lot of uncertain factors, not the least of which is the confusion as to ascertaining that a lethal epidemic is really underway and that it was a calculated act perpetrated by terrorists. Imagine how maddening it would be for AQ to have done something like that and have the CDC write it off to the world as a bad outbreak of the flu or something. But a chemical attack could be a lot smaller but oh so much more spectacular and leave no doubt as to the origins.....and that would provide the sound bites and photo ops for the rest of the century. A nuke, for them would be even better. I could see a bio-attack as a follow on to something else to throw the country into further disarray.
