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
By ICBMs were talking about missiles only not nukes - the delivery system. Israel has not test fired any ICBMs and you really need to test fire those rockets to see if they are working, etc. You can't just build a missile and know it will work without test firing.
The rest of your comments are irrational fantasy land type scenarios.
