A bit misleading. Political Islam is largely an invention of Moscow itself, which used Islamo-Marxism is a tool to turn the Muslim world against the United States and its allies. Many known Muslim terrorist leaders have had ties with the Russian KGB/FSB. In fact, Alexander Lintvenenko, the fellow who was poisoned by Polonium 210, had alleged that Russia had recruited and trained Al-Qaeda’s former number two man (now number one).
In fact both political islam and islamist terrorism are British invention. British intelligence is all the way behind Hizb-ut-Hahrir a first of it’s kind terrorist organization designed to deter Israel back to late 40s. Brits viewed Israel a threat and an American tool to take an upper hand over the British influence in the Middle East.
Soviets took a bit advantage from this crap in 70s, true but it was alive and well earlier.
If you really want to look into a Russian-designed regimes and Islamo-Marxism learn about Baathism and look at Saddam’s Iraq, Assad’s Syria, pre-Muslim Brotherhood Egypt and Lybia.
All of the above were secular lower middle class societies to some extent. Islamic extremism was brutally controlled and non-muslims were protected via KGB-style institutions.
This bears repeating (and remembering)!
