I wonder how much of this story had been deliberately falsified? It might have not been aircraft, other weapons could have been smuggled into Syria via the Iraqi border. It does freak out the mullahs and the chinless optometrist, so that’s good. It just might be disinformation.
Israel flew deep into Syria with impunity despite a bunch of new Russian anti-aircraft defense systems. I don’t see the disinformation angle here.
A poster on another thread said he thought that the air defense systems were ineffective because they had no targets. He thought that the Syrian facilities were destroyed by an American airborne laser system operating from far outside the Syrian borders. The "discarded" Israeli fighter auxiliary jet fuel tanks were in fact humped in by Israeli SPECOPS as a red herring, just to keep our advanced laser capabilities secret. It's an entertaining theory at least, although I don't know why we'd jeopardize a top-secret program when conventional means would work just fine.
Stop spilling the beans on the new flying saucers. :)
