The Russia-Iran-Assad axis and its useful idiots in the West claim that the United States created ISIS. Some of the loonier conspiracy sites that gleefully repost Russian propaganda allege that the Caliph of ISIS is a Jewish Mossad agent named Elliot Shimon or a CIA agent named Simon Elliot.
Elliot doesn’t exist, but ISIS’ Deputy Caliph Abu Ali al-Anbari, who was Saddam’s major general and a Baathist member, does. The Caliph’s right hand man, Abu Muslim al Turkmani, was also a Baathist and a lieutenant colonel in Saddam’s military intelligence organization before being killed by a drone strike.
Considering the history between Saddam and the USSR, it is likely that one or both of the Caliph’s deputies received training from Russian intelligence advisers during their careers. Turkmani’s DGMI in particular was closely entangled with the KGB. One of the reasons ISIS is much better than its Sunni Islamist opponents is that its top people had been trained by Soviet experts.
The ISIS blowback doesn’t lead to America, but in a completely different direction.
