If you read the whole article, the author of your UAE government-owned newspaper is at pains to downplay the Al Nusra/Al Qaeda fear-factor (in this and other articles) since the funding for such jihadis comes from Sunni-Salifist supporting (US military allies) countries such as Turkey Qatar and Saudi Arabia or the UAE,
And when your author speaks of "moderate religion" you might want to look up the role of Sharia law in UAE when it comes to the the freedom of women and homosexuals.
In turn, the arming of the better equipped and motivated Al Nusra/Al Qaeda and foreign jihadists by these countries is largely, at the very least, tacitly sanctioned by the CIA.
However, despite the claims of some conspiracy theorists, elements in US government would indeed prefer to keep the radical jihadist factor to a confined function ( present enough to justify to the home populace the obscene massive military spending and generate sufficient fear to accept ever greater homeland repression) but the cat cannot be put back in the bag.
The US use of jihadists is largely a blinkered, fragmented one--focused on the job at hand: destroying the Soviet Union, destroying Libya, causing chaos in Iran, Syria etc, with little concern for the very real long term consequences.
Additionally, continued direct assaults on Muslim populations by the US/allies generates ever more radicalized anti-western fighters which, in the larger picture, becomes a threat to future imperial control of target countries.
