Civil war began in Saudi Arabia.

It's difficult to fight an asymmetric war regardless.  Notice, however, that as soon as ISIS began using conventional equipment and tactics they got squashed.  That's because they turned themselves into exactly the kind of enemy conventional forces are designed to fight.  Other conventional forces. 

The whole "ISIS is a CIA front" thing is an issue of swallowing too much RT flavored koolaid, comrade.  

https://en.wikipedia.org/wiki/Operation_Cyclone

Operation Cyclone was the code name for the United States Central Intelligence Agency (CIA) program to arm and finance the mujahideen, in Afghanistan from 1979 to 1989, prior to and during the military intervention by the USSR in support of its client, the Democratic Republic of Afghanistan.

The CIA manufactured terrorism to defeat the USSR. Because of the CIA and U.S army, the grandfathers of ISIS got training and support.
The U.S "owns" Islamic insurgunts. This is history, not "conspiracy theory"
