On the Oryx blog context and detail for this not so quiet war:http://spioenkop.blogspot.co.uk/2014...ia-and-is.html

It starts with:
Israeli airstrikes on targets in Syria remain shrouded in secrecy, and are often subject to speculation about what has been hit this time. For instance, the recent raids on Syrian territory, during which just one Popeye air-to-surface missile was intercepted by a Syrian Pantsir-S1 SAM system, saw depots near Damascus being hit by Israeli jets, although the content of these is unknown. The actual locations and targets reported to have been hit do often not correspond with the truth. This post will try to make clear why Israel is bombing Syria and why it is getting away with it.

(Concludes) Essentially, both parties are waging a covert war spanning a large period of time. Syria (as well as Iran for that matter) use Hizbullah and other anti-Israel groups in the Middle East as a proxy to fight the war on their own terms, whereas Israel manages to strike at its enemies without any retaliation.
