The developments indicate Russian Federation may have turned its back on protecting Iranians, who were the targets of the Israeli airstrikes on Wednesday night.
Israeli strikes on targets in Syria last week took out several Russian missile defense systems and raised questions about the viability of Moscow's military equipment.
Russian Federation is Syria's ally.
Vladimir Kozhin, an aide to Russian President Vladimir Putin who oversees military assistance to other countries, told the Russian Izvestia daily that the systems are now not needed in Syria. "Such a ceasefire would have to guarantee Israel that Iran will cease its attempts to establish itself in Syria, at least for a few months, as well as cease its attacks against Israel". That same night, Israeli airstrikes reportedly wiped out the majority of Syrian air defenses in the southern part of the country.
Possibly seeking to de-escalate tensions in Syria, Russia will not provide Syria with the S-300 air defense systems.
Hassan Nasrallah claimed the recent strikes on the Golan Heights mean the Syrian war has entered a'new phase
Israel has long wanted Russian Federation to withhold its more powerful defenses from Syria.
The S-300 is one of the most advanced air defense systems in the world.
Israel said the targets the strikes, its largest in Syria since the 1973 war, included weapons storage, logistics sites and intelligence centres used by elite Iranian forces in Syria. But Israel's military released videos of the strikes showing the Russian-made defense systems getting hit by the Israeli missiles. In retaliation, Israel scrambled over two dozen jets to strike Iranian-affiliated targets in Syria. By all accounts, the attacks succeeded in taking out command posts, infrastructure, and munitions.
"On the other hand, it was clear to Israeli policymakers that if Israel showed restraint in the face of Iranian Quds Force's aggressions, it would erode Israeli deterrence power vis-á-vis Iran".
"The war in Syria is over". Still, Russia and the US have avoided coming to blows in Syria, even when Washington hit the targets of the Russian-backed Syrian government. But Russia, by denying Syria air defenses, looks to have turned its back on supporting the regional ambitions of Ayatollah Khamenei.
