Pitting muslims against other muslims is indeed a good idea.
My favourite. Chechen (pro-Russian) president Kadirov is muslim bastard, hug and criminal, former Chechen rebell and terrorist. And he hates Chechen rebells guts!
Russia captured him in 90es and amde him most faithfull dog, he showed to be brutal and sneaky bastard in clashes with rebells/terrorists.
Actually, Litvinenko before being shot, was investigating “warcrimes against Chechens” commited by Kadirov
Iraq-Iran war in 80es? Man, that was best of all! Wish it lasted for couple of decades...
