This means that [GASP!] fellow Moose-limbs were collaborating with JOOOooozzz!

The Muslims have proven themselves to be liars of the first order.
They're manipulating for their own purposes. I doubt there's any Israeli involvement favoring either side: it just doesn't profit Israel to get involved, it would only inflame them if they were.
From what I can tell, they're staying assiduously neutral. In fact, it would likely be better for Israel to lean toward the Known Enemy, Assad, as he kept a lid on things...of a sort.
My $0.02. YMMV. The Mideast is a messed up place.
