One can argue that they might but this is a hypothetical scenario that we all know that it is never going to happen.

But I think the reality that the only time it was used, it was used against civilian targets not military targets. And of course there is a justification here, it was for the greater good!

The other reality is isreal killed thousands of people before Oct 7th and did and will do. But of course there is a justification too, self-defense ..etc.

No, it can easily be argued that the reason is nuclear fallout that will affect isreal itself and other states will lead to regional war and disaster for isreal. This does no refute anything.
