I just can't see Israel ever in an open conflict with Russia or even Iran for that matter. Its just too dangerous for such a small nation . A situation like that is basically ww3 in my opinion because the US and EU would have to get involved .
The fact is (or at least I hope) the days of state vs. state direct conflict seem to be behind us. And although these proxy wars and guerilla warfare are still dangerous and brutal. I don't see and Israel-Russia or even an Israel-Iran conflict ever occurring . All sides realize that it would just be too catastrophic
