 In fact, it appears to be going well enough that the Iranians are covering the success by Assad's forces, supported by Hezbollah.

And this piece from Mehr explains why the Syrian successes are important.

"Al-Qusayr is a strategic region and for its mountainous terrain, it overlooks other surrounding regions, covering all connecting roads. As said before, Al-Qusayr was providing the route for arms and forces entry to Syria, and functioned as headquarters for terrorists to manage the affairs from and sent troops to different regions.

Having putting full siege on Al-Qusayr, Syrian army managed a great victory by overtaking large part of the city. Currently, whole south, west and east of Al-Qusayr are controlled by Syrian army, with northern part being only in terrorists’ control. During overtake, hundreds of terrorists were captured, destroying their spirit, and inflicting heavy costs to opposition forces."

And note this claim that the Israelis have special forces units operating in Syria helping the Al-Nusra Front. 

"Khabar Press news website reported Israeli Special Forces have entered Al-Qusayr to help Al-Nusra Front. Intelligence agents entered Syria from Lebanon to prevent Syrian army progress towards Al-Qusayr."

I find it hard to believe that the IDF would help Al Nusra itself. But what better way to de-legitimize Al Nusra than by connecting it to the Jews.
