Israeli Flyover of Syria Theory

The plot thickens.

Via Hot Air:

Debka floats a not-unlikely theory about that strange Israeli flyover of Syria a few days ago. Apparently, the IAF was able to jam the Russian-made Syrian anti-aircraft system; it so happens that Iran has the same system. You do the math.

Was it a dry run, so the Israelis could practice a pending attack on Iran, or just a veiled threat - a shot across Iran's bow to coax Ahmadinejad to rethink his nuclear ambitions?

The problem with an Israeli strike is that although they may be able to jam Syria and Iran's anti-missile systems, how will they defend a possible retaliatory rocket attack by Iran?
