Brit. look for the beneficiary and you'll know who is behind it(and I can assure your Islam/Arabs/and even ISIS aren't benefiting from this). you can call anything conspiracy just to discreet it really.
the reason I believe (I had really long talks with my western co workers about this) in what the western people consider as a "conspiracy" . Is because we live closer to it. I am Syrian and I've never met/seen/heard anyone who joined/knew someone who joined ISIS. this magical groups who overtook (or was handed) heavy weaponry from Iraqi/US military bases and controlled almost all the oil resources in Syria/Iraq, challenged the entire world and let's remember they grouped in 2013. that's only 3 years ago.
