(JNS.org) Israel has sent a warning to Russia over the transfer of advanced S-300 anti-aircraft missiles to Syria. Israel fears that the weapons could be a regional game changer, especially if it falls into the hands of terrorist groups like Hezbollah. Nevertheless, Russia’s Deputy Foreign Minister Sergey Ryabko defended Russia’s right to deliver the S-300s to Syria. “We consider this delivery a factor of stabilization [in the Middle East],” Ryabko said, Russia Today reported. Israeli Defense Minister Moshe Ya’alon told reporters when asked about the S-300s, “The shipments have not been sent on their way yet. And I hope that they will not be sent.” But if “God forbid [the S-300s] do reach Syria, [Israel] will know what to do.”
