Safer from what?

Israeli neighbors that are at peace with Israel are safe as well, e.g., Egypt and Jordan.

And what about Iraq, Syria, and Lebanon? And, in this latest case, Iran?

As far as I know they do not have peace treaties with Israel, so they are less safe by definition, no?

Also, Iraq and Iran are not neighbors of Israel, only Lebanon, Syria, Jordan, and Egypt are.

They're less safe on as demonstrated by the casualties they've sustained in repeated wars, inter-state and civil wars.

Iraq and Iran are both in the region, if not directly sharing borders with Israel.

So to answer the question I originally responded do, "did nuclear weapons make Israel safer", the answer is evidently yes.
