Some reality to counter the hype.
The Bottom Line
While there has been much consternation and alarm-raising over the potential for widespread proliferation of biological weapons and the possible use of such weapons on a massive scale, there are significant constraints on such designs. The current dearth of substantial biological weapons programs and arsenals by governments worldwide, and the even smaller number of cases in which systems were actually used, seems to belie -- or at least bring into question -- the intense concern about such programs.
While we would like to believe that countries such as the United States, the United Kingdom and Russia have halted their biological warfare programs for some noble ideological or humanitarian reason, we simply can´t. If biological weapons were in practice as effective as some would lead us to believe, these states would surely maintain stockpiles of them, just as they have maintained their nuclear weapons programs. Biological weapons programs were abandoned because they proved to be not as effective as advertised and because conventional munitions proved to provide more bang for the buck.
