Israel does not have any ICBMs (if it does it never tested them) and I don't think the Israeli would threaten Russia like that knowing the Russians can retaliate very easily - in any case such a threat did not happen - nor would it happen.
Putin is shocked SHOCKED to find Russian scientist helping Iran build a nuclear weapon.
Internet does say Israel has some ICBMs
Anyways one or two Iranian nukes could destroy Israel beyond repair but not beyond retaliation. This is where Israel nukes Moscow in vengeance. I would if I ran Israel
