I don't think Farhan is saying controlled by, but I would say Daesh is the product of a western 'figment' in that the idea was to fund an insurgency against those states that don't fall in line with American economic policy. Then, when the situation changes, the insurgents turn round and bite their founders in the arse.I personally do not think ISIS, etc. is as controlled as farhan states.
The Muhajideen, for example, were funded and trained by the US and Brits against the Russians. The Taliban were – some say – were funded by Pakistan to control access routes in Afghanistan.
Whilst I don't think anyone controls Daesh, it was and for all I know continues to be funded by certain Arab states.
As is becoming increasingly obvious in their rhetoric, Daesh is not so much pro-Islam and anti-Western.
