I do believe that Biowarfare is coming to the US from anti-Americans, whoever they may be. I am not sure that Ebola is the best agent but a possible agent. I don't think that we needed to bring Ebola patients to the US but I was wrong with how quickly they responded to therapy.
I do believe that Ebola will be used around the world as an agent. The projected cure of 2 Americans suggests that Ebola is not the killer that is of the greatest concern. I am more worried about airborne viruses like SARS and the 1917 Spanish Flu. SARS burned itself out via quarantine, otherwise it could have been a pandemic.
