Israel's insistence to both the USA and Russia that any Syrian peace agreement cannot include a permanent Iranian presence anywhere in Syria is no different than John F. Kennedy's giving Russia an ultimatum to withdraw their troops and missiles from Cuba. In 1962, after threats and warnings from the USA, Russian leader Nikita Khrushchev agreed to dismantle all Russian nuclear missiles based in Cuba and ship them back to the Soviet Union. Israel is correct to insist that Iran, a country that has repeatedly threatened Israel with annihilation, remove all their troops, as well as Hezbollah - and all other associated armed tribes fighting on their behalf in Syria.
The war drums are beating with Saudi Arabia and her Sunni allies lining up against Iran and her allies in what looks like a repeat of the Iran/Iraq war which was also Sunni VS. Shiite. The UN is totally ineffective and unable/unwilling to bring the parties to the table, and only the USA and Russia are capable of a real peace agreement - not one that guarantees that Israel will have a threat on their Northern border, which will push Israel to join Saudi Arabia in defeating Iran. Once that war gets rolling, there will be tens of thousands dead, hundreds of thousands of refugees flooding Europe, and Lebanon will also become entwined in this regional quagmire.
Both the USA and Russia, as anchor powers supporting opposite sides of this upcoming conflict, need to resolve this conflict peacefully by forcing Iran to leave Syria - or dig in for the long haul supporting their respective allies/surrogates with arms, weapons and ammunition for the foreseeable future. That area of the world does not need another conflagration, and Israel especially does not want to be drawn into a war between the Sunni and Shiites Muslims. With that said, Israel will not have a choice in the matter once missiles start falling in Tel Aviv.
