the greatest biological weapon is not anthrax or ibola or other known scare that US has introduced.. i think that the greatest weapon would be one that slowly wipes out the memory of a human being.. this would hard to detect because half of the time we take things for granted, like remembering where we had put the keys or how we tie our shoe lases.... the only thing that makes the world exist is our memory.imagine if slowly or even worse in just a snap we could loose our memory. remember " A mind is a terrible thing to waste". like any other attacks. this kind of virus would be in large numbers and in different places... just imagine.. people you know for your whole life will just vanish in your memory in just a snap, then if it gets worser you forget how to do the simpliest tasks like breathing..
