It’s muslin on muslin. Nasrallah has been the enemy if Israel for as long as I can remember, but now he’s against the US created ‘ITHIL’. Strange bedfellows.
Nasrallah is a Shiite, ISIS is Sunni - they hate each other - Nasrallah is fighting with Iran and Russia in Syria against all of the Sunni groups of which ISIS is the largest.
Nasrallah and ISIS both are ememies of Israel and both are on or near the Golan.
