Unlike the NPT, which had exceptionally designated two classes of designated contracting parties to have nuclear weapons or not, the BTWC has at least enshrined the same basic prohibitions and obligations on all States parties, including the obligation not to “develop, produce, stockpile or retain” such weapons, “take all necessary measures to prohibit and prevent development, the production, storage, acquisition or preservation of pathogens, toxins, weapons, equipment and media” and to destroy existing stockpiles. The BTWC`s aim to describe its military use as “repugnant to the conscience of humanity” was to “completely exclude the possibility of using bacteriological (biological) active substances and toxins as weapons”. It was adopted without any revision provisions.
