The HIV aspect you mentioned in your original post means that the virus can be carried and transmitted for an extended range/period, correct? Surely that factor is key in the virus's significant capacity for transmission and it's ability to travel the world (plus be difficult to treat). Wouldn't that in itself make this an idea bioweapon if the aim was specifically to create something deadly that travels far and wide. Are you assuming that a bioweapon would only be designed to attack a local area?
Have you watched the whistleblower video from Project Camelot back in 2010?
