Then why would ISIS attack American troops, if America was funding them?
Your “theory” makes no sense
ISIS was a new strain of terrorism that got out of control sort of like Qatari-funded with Israeli blessing Hamas did in Gaza.
ISIS bled right into Iraq forcing US military intervention and conflict with ISIS since then but at the beginning ISIS was a new strain unleashed to counter Russan-Iranian-Hezbollah help for Assad.
In those US backed Kurdish staffed ISIS prison camps in Syria I suspect recruitment in recent years to do MI6-CIA dirty work where needed.
Your noise and garbage make no sense.
