Following the September 11, 2001 (9/11) attacks, several “prophecies” circulated on the internet claiming the 16th century French seer Nostradamus predicted the crisis, leading to “Nostradamus” being the top search on Google and other search engines in 2001. Considering Nostradamus prophecies as popular eschatology, a dimension of political conspiracism, it is observed that while the hoaxes have never been attributed to a specific actor(s), the provenance of the prophecies which circulated on 9/11 are connected to a legacy of Russian Cold War-era propaganda. Additionally, several other conspiracy theories which circulated following 9/11 can be connected to Russia and its military proxy Syria. Considering conspiracy theories as a “populist theory of power,” leveraged by Russia in order to diminish American global dominance, a case is made that Russia is likely responsible for the Nostradamus hoax of 9/11 and similar “active measures” in Poland in 2010, Ukraine in 2014, and Hungary in 2015.
