Zionist writers on Wahhabism post 9/11 went much further than the US State Department in associating it with terrorism. If you want to know where Assadists get their version of Wahhabism, it’s from Zionists with the addition of the head-chopping stuff.
In one sweeping smear, they malign Islam & add nothing to an understanding of terrorism, extremism, war, occupation. The obfuscation lends itself to supporting Assad’s dictatorship.
In reality, Islam has as little to do with ISIS as Judaism has to the state of Israel.
