S-300s didn’t help last time the Israelis raided Syria...
I don't believe that the S300s were there when that raid occurred. And the S300s are under Russian, not Syrian, control.
.....probably because there were no S-300s deployed. The Tor-M1 is an okay short-range SAM, but it is no S-300.
I still believe the Israelis can find an effective solution against the S-300 (and similar) based IADS, and they have practiced against Greek S-300s, but it is an oft repeated error on FR that the Israelis hit Syrian S-300s. Syria simply didn't have them, and the system they had was a mix of S-125s and Tors, with the short range Tors being the most sophisticated SAM at play.
