Four distinct elements are involved - though possibly taking place unconnectedly with each other, in reality - in the course leading to the anthrax letter attack: the AS supplier; the basic powder technology supplier; the origination of the subsequent powdery bacillus modeling; and the SSP producer. The first three might be completely innocent, according to the following clustering. Namely, the AS supplier (to either Basson, el-Hibri, or another “legitimate” intermediary) was a U.S./British laboratory; the basic powder technology supplier was Denmark’s Niro; the origination of the powdery bacillus modeling was USSR/Russia, which preferred BT rather than BG, because the former is a much better simulant for BA spore powder; and the SSP producer - the fourth and cardinal element - was plausibly Iraq, thanks to having obtained and employed the first three elements together, thereby forming a superb integral in Iraq. Alternatively, Soviet or formerly Soviet institutions could constitute the first three elements altogether (or two of them), and al-Qaeda itself could be the intermediary (and the perpetrator, but not the SSP producer). Notably, and in spite of continuing claims that no solid connections - including the contexts of CBW at-large, as well as the 2001 Twin Towers attack - existed between al-Qaeda and Iraq, the opposite has increasingly and firmly been emerging since the 2003 invasion of Iraq.52
