IRANIAN AIR DEFENSE SYSTEM VULNERABLE TO U.S.

"... from the way Damascus described the episode... the electronic systems and radar of the Pantsyr-S1 air defense missiles were a letdown because they failed to down the intruders and therefore leave Syria and Iranian airspace vulnerable to hostile intrusion. Such information on the Russian weapons systems sold to Syria and Iran is essential to any US calculations of whether to attack Iran."
