Israel has nothing to fear from russia, they are not enemies and you will never find them in a situation where israel needs to fear that they are in range of russian missiles. Plus, israel is made of stern stuff, if russia was swinging its long shiny missile stick around to try and scare them, im pretty sure the israelis would just tell them to piss off. I dont get why you think this had anything to do with it.
Yup both of them are not hostile to each other but they have their differences unlike US and Israel. Well Russia can annihilate them not the latter ( a simple fact and their Missile defense system aren't capable against Russian arsenal. Let it be Barak-8 , David Sling, Arrow-2 is still a cagey product with no success and Iron Dome .
